It's important: Please note that the YONGNUO 40mm 1: 2.8 (YN40mm F2.8N) lens at the time of writing of this review (spring 2018) exists only in the modification for the Nikon CZK. Usually third-party lenses such as tokina, Tamron, Sigma, Carl Zeiss Present simultaneously for several systems. Whether YONGNUO 40mm 1: 2.8 will be released for the Canon system or some other system is still unknown.

In short

Yongnuo 40 / 2.8 is a compact and cheap fast prime lens for full frame Nikon FX cameras. Has a built-in focusing motor, and therefore should work on all amateur cameras in the series Nikon DX. Optically not bad, but there are features with focus and metering.

At the time of this writing (Spring 2018) Yongnuo 40 / 2.8 - the smallest и the easiest autofocus fixed lens with built-in focus motor among all Nikon SLR lenses.

About 'pancakes'

Small lenses with a small body thickness are commonly referred to as 'pancake lenses' or simply 'pancakes'. As an example, classic modern pancakes can be considered Canon Lens EF 40mm 1: 2.8 STM (thickness 22 mm) or SMC Pentax-DA 1: 2.8 40mm Limited (thickness 15 mm).

Nikon, at the time of this writing, has no auto-focus pancake lens. Therefore, one of the main features and advantages, compared to the original lenses, the Yongnuo 40 / 2.8 is considered its compact size and light weight.

The maximum length of Yongnuo 40 / 2.8 (without covers) is 45 mm, the length of the protruding part of the lens mounted on the camera is 35 mm. The weight of the lens is only 130 gram.

But as it turned out, many original Nikon Nikkor lenses are still thinner:

As a result, Yongnuo 40 / 2.8 is noticeably more than Nikon AF Nikkor 50mm 1: 1.8D and only a little lighter than him (130 против 155 gram). Thus Yongnuo 40 / 2.8 is not a pancake lens.

Due to the fact that the Yongnuo 40 / 2.8 has a fairly wide body diameter, which is 74 mm, and the length is much shorter - 45 mm, its proportions still resemble pancake lenses.

Video review Here

The closest to the value of the focal length and aperture to Yongnuo 40 / 2.8 is the original Nikon DX AF-S Micro Nikkor 40mm 1: 2.8G SWM. But, in fact, these are completely different lenses:

YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)

YONGNUO 40mm 1: 2.8 (YN40 mm F2.8N)


The lens came to the review completely new. The front and rear lenses were protected by some special thin film of blue color, which was inconvenient to remove from the front lens.

In a small box is a coupon with a release date, instructions in Chinese and English, a bag of desiccant and the lens itself with a front (YN-58) and a back cover.

The box is made in the color typical of the golden boxes from under the Nikon Nikkor lenses. In the box, the lens is in enough lasting special cardboard container.

The lens is built well (but not good). Yongnuo 40 / 2.8 has metal mount mount. The focus ring is rubberized. It is stated that the contacts of the microcircuits are gold-plated to improve the passage of current and avoid corrosion. Focus ring has a small backlash - this is the only thing that really betrays its cheap / inexpensive Chinese origin in the lens.

Among the drawbacks of the assembly, I want to highlight the fact that not all Yongnuo 40 / 2.8 lenses come with a hood and a case for transportation. Also, it is not known which particular blend will fit Yongnuo 40 / 2.8 and will not give vignetting. Yongnuo 40 / 2.8 has special grooves for installing a bayonet type hood. It is good that the front lens is deeply recessed in the frame of the body (especially when focusing on infinity), which allows you to use the lens without a hood and problems in side light.

Case design reminds Yongnuo 50mm 1: 1.8Yongnuo 35mm 1: 2 / Nikon 50 / 1.8G.

It is a pity, but the number of aperture blades is 6 pieces. Yongnuo 50mm 1: 1.8Yongnuo 35mm 1: 2 / Canon EF 40mm 1: 2.8 STM have 7 petals

Firmware Upgrade

On the front of the lens, the Yongnuo 40 / 2.8 has a USB port that allows you to update the software (firmware / firmware) of the lens. This feature first appeared in Yongnuo 40 / 2.8 and Yongnuo 100mm 1: 2that were presented at the same time.

Unfortunately, the functionality of the YNLensTool Updater Version 1.00 program, which is responsible for working with the lens, is very meager. Can just see the current firmware version and update it to a new one. Firmware versions can be found on the official website. I found the firmware for my Yongnuo 40 / 2.8 here.

A widespread USB 2.0 MICRO-B port is used to connect to the lens (most mobile phones use just that). A USB cable is not included. To connect, I used the USB cable for my Android phone and without any problems updated the firmware from V1.01 (2017.09.28) to V1.02 (2017.12.26). The procedure took less than 10 seconds.

A firmware update, most likely, allows you to improve the compatibility of the lens with new cameras, improve the autofocus, eliminates some other errors. It is very bad that there is no way to roll back (restore) an older version of the firmware.

To upgrade the firmware (software) of the lens:

  1. Turn off the camera, detach the lens
  2. Open YNLens Updater to Update
  3. Attach the lens to the computer using a USB cable. If everything went well, the program will automatically detect the connected lens
  4. Click [Browse] and select the file with the desired firmware
  5. Click [Start] to start the update. Wait for the update to complete.
  6. Disconnect the cable and enjoy.

I did not notice any noticeable difference before and after updating the firmware.

YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)

YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)


The lens has built-in focus motor DC-type (DDirectly Current Motor- ordinary DC motor). To be precise, the Yongnuo 40/2.8 is an analog of the Nikon series lenses AF-I. Unlike lenses Nikon AF-Sthat use ultrasonic focusing motors Nikon SWMold lenses Nikon AF-I use a built-in buzzing micro focus motor similar to the Yongnuo DC.

The lens will automatically focus on all Nikon DSLR cameraseven on amateur series models Nikon DXthat do not have a built-in focus motor: D40, D40x, D60, D3000, D3100, D3200, D3300, D3400, D3500, D5000, D5100, D5200, D5300, D5500, D5600as well as mirrorless cameras Nikon Z with adapter FTZ / FTZ II.

When focusing, the motor is noisy. The noise is small. Yongnuo 40/2.8 makes less noise than motorless Nikon AF Nikkor 50mm 1: 1.8D or Nikon AF Nikkor 35mm 1: 2D. At the same time, the Yongnuo 40/2.8 is not much more noisy than compact ultrasonic motor у Nikon DX AF-S Nikkor 35mm 1: 1.8G.

Auto focus on the lens medium (closer to slow). Focusing time from infinity to MDF and vice versa is significantly longer than the original Nikon DX Series Lenses. Focusing time from MDF to infinity is slightly longer than in the opposite direction.

When used on cameras Nikon D90 (with unpretentious Multi-CAM 1000 focusing system) and D100 (with very simple Multi-CAM 900 focusing system) The lens sometimes makes focus errors. Errors are not systematic. About 10-15% of shots have obvious problems with focus accuracy. On camera Nikon D700 (with advanced focusing system Multi-CAM 3500FX) the lens is often mistaken with focus. About 40% of shots have clear focus accuracy issues. During real shooting, such a number of errors annoyed me very much, I had to duplicate all the key moments of photography with an extra pair of frames.

On camera Nikon D90 и Nikon D700 I checked the presence of the back and focus front at different focusing distances (infinity and MDF as well). Pictures taken using the Live View mode (which does not suffer from back / front focus) were used as a measure. Focusing accuracy using phase sensors completely coincided with the Live View mode.

When focusing, the front lens group moves in the middle of the frame of the housing. When focusing the lens does not change its size, and the filter is wound on a fixed outer part of the frame of the housing (watch animation) This type of focusing can also be found in Nikon 50 / 1.8G or YONGNUO 35mm 1: 2. You can easily use all sorts of filters.

The focus ring is rubberized and rotates approximately 135 degrees in manual focus mode. When extreme positions are reached, the ring abuts.

The focus distance scale rotates in the opposite direction to the rotation of the focus ring. Manual focus is quite convenient. The ring rotates smoothly and quite pleasantly. The direction of rotation of the focus ring is opposite to the original Nikon Nikkor lenses.

There is a 'AF-MF' (auto focus / manual focus) mode switch on the lens body. Switch positions are swapped compared to the original Nikon DX 35 / 1.8G ('AF-MF' <-> 'M-M / A'). During auto focus focus ring remains stationarywhile it can be freely rotated 360 degrees without any effect on focusing. Unfortunately, unlike many original Nikon lenses, the Yongnuo 40/2.8 does not support continuous manual focus control Nikon M / A.

The lens has a window with a focus distance scale in meters and feet. The number of values ​​on the scale is small, the scale itself is not very useful.

The minimum focusing distance is 30 cm and the maximum magnification ratio is 1: 5.6 (0.18 X magnification).

YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)

Focus Features:

  1. Yongnuo 40 / 2.8 has no focus problems in Live View (tested on Nikon D90 и Nikon D700), but it focuses very slowly (the problem of focusing by contrast is more a problem).
  2. Yongnuo 40 / 2.8 has a slightly pronounced 'Focus Breathing' effect (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.
  3. Focusing is performed by simultaneously moving the entire lens block (all lenses) relative to the focal plane.
  4. Yongnuo 40 / 2.8 does not have a hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens to infinity under any external temperature conditions. For accurate aiming at infinity, you cannot just bring the focus ring to its extreme position.
  5. Focus shift (shift-focus) is missing.
  6. Important: Yongnuo 40 / 2.8 is a third-party lens. It may happen that it will not work correctly with the new Nikon cameras, which will be presented after the announcement of this lens. Details on this issue are considered by me. here... Also the lens may behave strangely with some other cameras. Some users have noticed various features of autofocus behavior on a particular camera. It is not known whether the possibility of updating the firmware will help.
  7. Unknown compatibility with teleconverters.
  8. Unknown compatibility with FT-1 adapter for system cameras Nikon 1.

Exposure Issues

Important: some cameras have a problem with automatic metering exposure. On camera Nikon D90 with any metering settings exposure the built-in exposure meter lies about -2 steps (i.e., you need to make a correction exposure +2 EV). A problem with such a large deviation from normal exposure I meet for the first time.

On camera Nikon D100 with any metering settings exposure the built-in exposure meter lies about -1 step (i.e. you need to make a correction exposure +1 EV).

On camera Nikon D700 metering problems exposure did not have.

Yongnuo 40 / 2.8 incorrectly indicates / transmits focusing distance to the subject. The camera always receives only distance values ​​equal to 38 cm. Most likely, the problem with correct exposure metering is due to incorrect lens flashing or poor compatibility with some cameras.

At the same time aperture the lens expressed in T-stops corresponds to similar lenses with F / 2.8. I compared the indicators bar charts for Yongnuo 40 / 2.8 s lenses Sigma Zoom 24-60mm 1: 2.8 EX DG, Tamron Di II SP 17-50mm F / 2.8 VC и Sigma DC 18-50mm 1: 2.8 EX MACRO HSM with the same settings. The exposure was the same.

UPDATE: In the case of YN 100/2, a firmware update was able to cure the lens from a similar ailment, therefore, most likely, sometime a new firmware should come out that way, which will cure the lens from exposure problems.

Image quality

In general, the Yongnuo 40 / 2.8 is optically good and even good. In terms of image quality, it does not lag behind the original Canon Lens EF 40mm 1: 2.8 STM. Actually, the optical circuit of Yongnuo 40 / 2.8 was most likely copied or taken as a basis from Canon Lens EF 40mm 1: 2.8 STM. Built-in profile for Canon Lens EF 40mm 1: 2.8 STM in most popular RAW converters, Yongnuo 40 / 2.8 removes some optical flaws well.

The Yongnuo 40 / 2.8 is the first lens from Yongnuo to use aspherical elements.

  • at the edges of the frame, sharpness becomes acceptable after f / 4.0
  • good / excellent resolution in the center of the frame on covered apertures (after F / 4)


  • the overall level of distortion is at a level typical for such lenses
  • the nature of distortion is unified, easily corrected in the editor



  • on F / 2.8 there is a small amount of spherical aberrations that go away already with F / 3.5
  • the strongest chromatic aberration visible at the edges and corners of the image
  • when closing to F / 4-F / 10 HA are slightly reduced
  • general level HA is at the level typical for such lenses


  • color rendering is neutral, pleasant
  • pronounced effect of 6 ray star on heavily covered diaphragms
  • a small amount of glare in the backlight, a slight drop in contrast in the side light. Immunity is at the level characteristic of such lenses (example)
  • bulbous bokeh (concentric circles on blur discs) due to an aspherical element (example)

F / 2.8 - pretty low aperture as for a fixed lens. The F / 2.8 value is only 60% higher (2/3 steps) than the F / 3.5, which is used in the vast majority of standard zoom lenses.

My experience

Yongnuo in just a couple of years got to aspherical elements in its lenses and the ability to update the lens firmware. At such a pace, you can make a joke, in a couple of years Yongnuo will produce TOP 70-200 / 2.8 with a stabilizer.

Unfortunately, problems with exposure metering and uncertain focus do not make the Yongnuo 40 / 2.8 attractive for everyday use. But still I decided to leave it as a lens for all occasions, which I do not mind.

Price tags on Yongnuo 40 / 2.8 and Yongnuo 35mm 1: 2 very close. I would choose exactly Yongnuo 35mm 1: 2. The latter is a more balanced solution. One of the main advantages of Yongnuo 40 / 2.8, due to the fact that it should be a pancake lens, turned out to be false (Nikon 50mm 1: 1.8D AF far less than the hero from this review).

Those who are looking for an original pancake lens can look at the manual oldies:

If you need a small auto focus lens, then Nikon 50mm 1: 1.8D AF Nikkor will be just right (only for cameras with a focus motor).

YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)


The Yongnuo 40 / 2.8 is a nice little lens. Cheap, lightweight, optically good. But, depending on the model of the camera, there are serious features with autofocus and exposure metering.


  1. very light weight (Yongnuo 40 / 2.8 even lighter Nikon 50mm 1: 1.8D AF Nikkor)
  2. compact size (the smallest lens for Nikon cameras with a focus motor)
  3. good build: nice-to-touch plastic, metal bayonet mount, rubberized focus ring, bayonet type hood
  4. low cost (similar Canon Lens EF 40mm 1: 2.8 STM costs 2 times more expensive)
  5. USB port with firmware upgrade option. The function should help solve the compatibility problem with different cameras (especially with new models), and also improve the overall performance of the lens
  6. aspherical element in the optical circuit
  7. built-in focus motorcompatible with the youngest line of cameras Nikon DX without focus motor
  8. virtually internal focus
  9. lack of rotation of the focus ring during auto focus
  10. focus ring rotates approximately 135 degrees
  11. presence of a window with a focus distance scale
  12. depth of field scale
  13. no focus shift
  14. small MDF, only 30 cm (magnification ratio for macro photography is better than Nikon 50mm 1: 1.8D AF [1: 5.6 vs 1: 6.6])
  15. good optical performance, including confident sharpness at F / 2.8 in the center of the frame


  1. limited options for adjusting the lens via the USB port. You can only upgrade the lens firmware. Cannot roll back firmware to previous version
  2. unsuccessful, in terms of design, location for the USB port. The model Yongnuo 100mm 1: 2 this port is located on the side of the chassis
  3. backlash of the focus ring, because of this backlash, the lens feels like a cheap plastic product, and manual focusing is not as smooth and comfortable as we would like
  4. periodic or frequent auto focus errors (depending on the camera)
  5. medium (closer to low) focus speed
  6. lack of constant manual focus control
  7. incorrect indication of the focusing distance (the lens always reports to the camera only one value about the distance to the subject being shot, similar to Nikon NON-D)
  8. focus ring and distance scale have different directions of rotation (psychological discomfort)
  9. slight noise from the focus motor
  10. the direction of rotation of the focus ring is opposite to the original Nikon 40 / 2.8G. The 'AF / MF' switch directions are opposite to the original Nikon Nikkor lenses
  11. problems with metering on some cameras (e.g. Nikon D90 exposure compensation required + 2 EV)
  12. F / 2.8 is a fairly low rate of a fixed lens with a similar focal length (Yongnuo 40 / 2.8 a step darker Yongnuo 35 / 2 )
  13. no hood included, unknown hood type, unknown compatibility with original hoods
  14. relatively large diameter of the filters (58 mm for Yongnuo 40 / 2.8 and, as an example, 52 mm for Nikon 50mm 1: 1.8D AF)
  15. lack of basic dust and moisture protection (in Nikon 35mm f / 1.8G DX, for example, there is rubber lens mount seal)
  16. small effect of 'Focus Breathing' (changes in viewing angle during focusing)
  17. there is no tag for working in the infrared spectrum, the depth of field and focus distances are very small
  18. six aperture blades (original Canon 40mm 1: 2.8 STM seven blades), insufficiently round discs of blur on the F / 5.6-F / 22 apertures
  19. there may be incompatibility with some cameras and / or teleconverters (no exact data)
  20. lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of distortion (distortion, vignetting etc.)
  21. lack of lens profile in popular RAW converters (perhaps this is only a temporary drawback)
  22. the survivability of this lens and the variation in quality are unknown. Little information on Yongnuo Certified Lens Service Centers

Please ask all questions regarding the lens in the comments, I will definitely try to answer. Comments do not require any registration or any personal data.

Comments: 97, on the topic: Review YONGNUO 40mm 1: 2.8 (YN40mm F2.8N)

  • DmitryK

    Waiting for a review on this glass.
    Arkady, thanks!
    Damn, it would be better if Yaga did not put her motor, but made her glasses under the screwdriver carcass motor.
    I understand that the owners of carcasses with motors are unlikely to look at yagi, but still ... focusing with a screwdriver is more reliable.
    PS> If Sigma ART could be so easily and easily updated via USB. The beauty :-)
    I took the cable from the old phone, stuck it into the lens with one end, and into the laptop / pc with the other and updated it as needed ....

    • DmitryK

      And even without a motor, this glass would be even lighter and more reliable ...

      • Arkady Shapoval

        There is Yaga 35/2, there are fewer jambs.

        • DmitryK

          I have Nikkor 35 / 2D, because I don't need such a yaga :-)
          But an inexpensive analogue of Canon 40 / 2.8 would be interesting.
          It is hoped that Yaga will finish this glass.

          • Arkady Shapoval

            I think they added usb for a reason, and they still have to fix the firmware. The network has data that on some cameras the problem with exposure after the firmware disappeared.

          • Vyacheslav

            I also have a Nikkor 35 f2 screwdriver on a d610 carcass. Focuses slowly and uncertainly.
            Although the screwdriver zoom tamron is also much faster, it means the matter is not in the carcass.

            Will youngnuo with its motor be worse?

            • Pokemon

              Vyacheslav, this is strange. Try 35 / 2D on the D750 or D810.
              I focused very quickly on the D700, and almost instantly on D3s, D4.
              On D4, no complaints at all. Only on a completely open are there mistakes, alas. Starting from 2.8 there are no problems at all under any lighting conditions.

        • Andrey Vernnicno

          Arkady, used to use 35mm f2 youngnyo nikon before, it was enough for six months of normal work, then he began to wash in the left corner of the frame. And in general he could use it calmly, without fear for an exchange, only from f2,8. Plastic colors. Deshka 35f2 is not sugar, but it is much better than youngny, after all in terms of reliability, for a reportage, for sure.

  • Peter Sh.

    Maybe the lenses from Baba Yaga work through a stump deck, but they have a whole division of free field testers like you and me. They will check everything and put it in detail on the Internet. Matyuki can be ignored, production costs.

    • Arkady Shapoval

      I personally like Yongnow. The decision to make cheap, really cheap light fixes is very healthy. Even this Yaga I still give a good drive to d100.

      • Peter Sh.

        I completely agree. They are smart guys, I’m sure that they will make Nikon and Kenon sweat.
        Yes, and Sigmu too.

      • NE

        It is still cheap and light. As soon as the quality is brought to the level (in 5-6 years) they will come up with a new brand and this "Yaga" will cost like Sigma & Tamron ... (see BBK -> OPPO) By the way, it's not a fact that the lens is made in China. There are examples when China, in turn, “takes” production somewhere, for example, to Vietnam, where the labor force will be cheaper. And soon, probably, in the Russian Federation ...

        • Cryptor

          Yes, that's the same auto-focus Yong 14mm 2.8 for some $ 485.55

        • Denis

          they will transfer all production to Mars, infa 100%

          • NE

            Mars still needs to get off its knees to start

        • Peter Sh.

          Yeah ... The freshest Samyang 14mm f / 2.4 Premium already costs 800 bucks. Manual. Nightmare.

  • lynx

    In general - “for loving 40 mm”.
    for crop 35 / 1,8 is still more practical and faster, for ff ... well, you can laugh

    • DmitryK

      For evening and night walkers, fast fixes at 28-40 mm, IMHO, it is.
      PS> Lynx is back :-)

  • Peter Sh.

    By the way, a couple of months ago I shot competitions and unexpectedly noticed Yongnuo flashes from colleagues. I learned from radio synchronizers, I have the same one. Colleagues were not at all embarrassed and ran from morning to night.

    So I don't know, I don't know ...

    • Nicholas

      Why is it shy then? : D

      • 123

        Well, like a non-kosher Chinese technique.
        I’m still waiting for someone to attach any yagu to D4 / D4s / D5 or 1Dh / 1DhMk2.
        Just a photo of any of the above carcasses with yagu already breaks consciousness and explodes the brain)

        • Arkady Shapoval

          Here и here I have it on a Canon 5Dsr, and nothing, 50 megapixels is easy.

    • anonym

      Unlike optics, the Chinese troika Yongnuo, Godox, Jinbei in strobing equipment strongly steps on the heels of eminent competitors, and overtakes some characteristics. In the optics market, nothing of the kind is expected in the coming years.

      • Foreign land

        Well, all the fuf at the boot with Nikon relieved….

      • Sultan

        partly yes. the above brands make good outbreaks, at about SB-700 level it can even. But the Nkion has an SB-910, just out of competition.

  • Valentine

    Thanks to Arkady for the thorough review. Concerns about this glass were confirmed. It seems to me that the best for YN for Nikon is still 50mm. In size, it has the same diameter, in length only + 20mm (for me it is not important to have a camera depth of 100 or 120 mm). At the same time, fifty dollars is deprived of these shortcomings with focusing and metering, has a large aperture of F1.8, sufficient sharpness and costs less than that. There is a difference in the focal length, but again it’s more familiar than 50mm or 35mm.

    • Arkady Shapoval

      To me personally Yongnuo 35mm 1: 2 liked more.

      • Valentine

        Me first too. Then I realized that a fifty dollars is more predictable in the open: there are no misses in focus, fast in different conditions, sharp enough, fewer problems with color reproduction. Given the price, I would take it to the crop in addition to the regular whale. 35 doesn’t give such an advantage in aperture ratio and more often misses in focus, and even costs 10-15% more.

  • Peter Sh.

    About the wrong metering. I had the same thing on the YN 100mm f / 2 until I updated the firmware.

    With AF, sharpness, color reproduction, and so on, the YN100mm was fine, by the way. No complaints at all. Even worked on D3s without any problems. But I had to return it because of the wild cushion-like distortion. Maybe I got a defective one, I don’t know.

    • Arkady Shapoval

      The firmware did not help me. But it’s good news that weaving under Nikon is working fine.

      • Peter Sh.

        I finally made up my mind and took another copy of the Yongnuo 100mm f / 2 instead of the first one that I returned back.
        Distortion is already much better, it seems that he really was defective. But still it is, at about the same level as Kenon. AF in speed and accuracy is somewhere the same as the Nikon 85mm f / 1.8D. Yaga really does not like back and side light. definitely need a hood. I forgot to mention this last time.

        The other day there was an opportunity to check it a bit in extreme conditions. The task was to find out the noise level, contrast and so on, hence the low quality of the picture.

        Filmed at night, with hands. Shutter speed 1/80, f / 2 aperture. Neutral profile, all by zeros (including sharpness). Shumodav is disconnected. Distance to the waterfall about 500 meters:

    sooner or later, this company will begin to produce really good lenses, yet they are gaining practice now. Although really top-end lenses in China cost a lot of money, such as, for example, the parting Laowa 105/2 SFT (600 dollars) and Zhongyi 85 / 1.2 (620 USD).

    • Arkady Shapoval

      У Yongnuo Lens 14mm 1: 2.8 the price tag is already 500 dollars. The network already has information that it is optically no worse than Canon EF 14mm f / 2.8L II USM

        • Arkady Shapoval

          Only for Sony E and over $ 600 price tag.

          • NE

            So I took myself such a non-autofocus in my time in less than 400USD. 4 years ago there was no yongnuo 14mm, and now I would have taken samyang anyway. It is interesting to hear the opinion of those who intensively used yongnuo optics for 3 4 years

            • Valentine

              Actually, it’s not so important how reliable this 14mm yongnuo is. It would be better to understand what quality the picture is. After all, non-autofocus samyang can simultaneously be both a cheaper and better solution. Yes, the best even in the absence of autofocus. On super-wide and fisheye autofocus may not be important at all. It all depends on the use of this lens. Due to their small focal length and covering of the diaphragm, the hyperfocal comes very close, therefore for a huge number of frames it is enough to simply set the infinity and shoot without touching the focus ring at all.

              • NE

                Therefore, he spat at the time on autofocus. And why is reliability not important?

              • Valentine

                That is why: even if it is more reliable than the native Nikon, the ratio of picture quality and price will still be decisive. The price is already clear - not small. If in quality it is more problematic than Samyang, then autofocus and reliability in most cases will already have little to do with it. Samyang is simply preferable. And only in those cases for whom autofocus is important at ultra-wide, they will delve into its parameters and evaluate its reliability.

              • NE

                Let's try to collect and structure your thoughts (in my opinion, really ingenious) in order to understand the semantic load of your last post (I still can't do this on my own): 1. About autofocus at small focal lengths, and so everything is obvious, let's forget this ... The allusion to a goblin is understandable, but I was just surprised by the appearance of autofocus in samyang, in principle, in fact. 2. The fact that additional pribludy are useless with an unsatisfactory picture (the main task of the lens) is also obvious. 3. "reliability is not so important - the main quality of the picture" - I almost quote you. And here is the last most interesting thing, and therefore I would like to receive your motivated judgment in detail.

              • Valentine

                SV, do not dig too deep. The thought was simple. Yongnuo 14mm niches prof. lenses, equipped with autofocus and is quite expensive. When I solve a problem whether this lens is interesting to me or not, I first of all want to know about the picture that it gives. If the picture is better than the manual and cheap Samyang, then I will think about it and watch the rest of the characteristics. And if the picture is not better, then I won’t even think about it. Just stay on the manual modification of Samyang, the benefit of 14mm autofocus is not always needed.

  • Alexey de Paris

    Thank you for the review, good optics and sharpness and drawing, but nothing can be said about durability. I never used Yong and once again made sure that the good old nikkor af 50 mm 1.8 is better.

    • Foreign land

      Our reviewer hero didn’t confuse anything with the good old?

  • Dmitriy

    Arkady, is it planned to review yongnuo 100 / 2.0 for nikon?

    • Arkady Shapoval

      Yes, I plan. I think a little later I will buy it for review. 100 mm in the studio is inconvenient, you need to drive good weather outside, but we still have snow.

  • Sergei

    Where did so much advertising come from, 7 banners per article, are things really bad? Impossible to read

    • Arkady Shapoval

      Ads from Google. The site requires maintenance, and it’s not for nothing that I write “Recently, my blog 'Radojuva' has been demanding huge costs for maintenance and filling with new materials.” The same hosting costs about a piece of bucks a year, and I had to move to another one, since the previous one was simply bent from the number of visitors.

      As for the number of ads, it is quite normal, this review of 40.000 characters (which is 10 pages of plain text in WORD or 25 pages of text in the same place with pictures) accounts for 5 ad inserts (+ left and right sidebars and + advertising 1 insert in the comment).

      If you want to calculate the money invested, then 90 bucks went to the lens for this review and 15 bucks each for 2 studio rents (shooting on TPF terms at my expense) + 10 bucks for D700 rent for a couple of days.

      • Н

        Really 25 pages. I never thought about the scope of the reviews. Yes, and the text seems to be without water and advertising snot, concisely like. But advertising is certainly not very good.

        • Valentine

          Friends, we either watch ads or pay real money. Someone else's work must be paid by those who consume its results. This is about at least recouping the costs of preparing a review. And it seems to me that viewing ads is so trifling for us that it wasn’t worth readers to raise such a question at all.

          • Peter Sh.

            Someone will always be dissatisfied with something.

  • toniwahid

    In our area, summers are short and cool, so for many years now we have been growing potatoes under film. In order to accelerate the process of tubers ripening, we necessarily germinate them. As a result, already at the end of May young potatoes flaunt on our table. Those who are going to grow potatoes for the first time under a film shelter need to remember that it is important to observe the temperature regime. On sunny days, the temperature under the shelter rises to + 45 ° C, which means that it must be opened for ventilation. If you use agrofibre instead of a film, then it is not necessary to open it, since it passes air.

    • Arkady Shapoval

      It seems coffee is better.
      Seriously, show me where in my text is there such a canvas with water that I have to read?

      • Denis

        maybe contextual advertising crawled out

        • Arkady Shapoval

          No, there are only banners and teasers, the site does not show text paintings.

  • anonym

    China has only cool prices, I'm waiting for "defiramb" when this China starts to break. one acquaintance filmed the floor of the wedding with a Chinese puff, the second one took off after half a year. I do not believe that it is good quality. in photography such economy is questionable

    • Denis

      Chinese flashes are good, only TTL does not work for everyone :)

    • Valentine

      Instead of using simple amateur equipment in conditions where professional is required. You really counted for 2,5 thousand rubles. to get everything the same as what the flashes give for 20-30 thousand? Really? This is a budget (again - budget) amateur equipment for appropriate use.

      • NE

        IMHO, you need to take normal equipment for any purpose (prof. And amateur). If you seek some compromises, then weigh the risks. And then take the consequences of your choice or reserve yourself somehow. But there are good compromises in the subject of outbreaks, but this is not yongnuo, of course, and the difference in price is not many times.

        • Valentine

          To each his own. For example, I consider it a normal decision for a younger carcass with a whale to buy a fast Yongnuo 50mm F1.8 and a Yongnuo 586 flash or an even cheaper copy of Triopo 586. For family shooting (which is what millions of users of such cameras actually do) this is a very budgetary and universal solution: here are portraits with blurring the background, here is the solution to the issue of insufficient light and low working ISO, etc. Those. a decent improvement in image quality at very high costs. The price of this kit will be 7-9 thousand rubles. and at home use it will last for a very long time. In this case, it is not necessary to spend 30-40 thousand rubles. Yongnuo, it seems to me, has guessed with a niche. You just need to adequately evaluate this product and your needs.

          • Arkady Shapoval

            If you know how to work with technology, then Yongnuo make very tasty suggestions.

            • NE

              I agree to whom the mare’s bride is. But seriously, a couple of questions: a) how the attractiveness of the proposal in this case depends on the user's qualifications? b) what kind of additional skills (skills, qualifications, etc.) are needed to work with youngnuo regarding SB-700/910?

              • Arkady Shapoval

                a) inexperienced users who can not cope with difficulties, will not be able to properly use the problematic lenses. For example, it will not be difficult for me to amend the exposure +1 and shoot on this lens on the Nikon D100 for my pleasure (for which he actually bought, because I CCD Shy Fetish) I also do not need a slow focus for my personal (non-commercial) purposes, I do not suffer or worry that this is not a USM bullet. The same goes for tenacity. Perhaps my hands and eyes are so petrified that they make me focus any lens in any environment.
                Also, having my own experience, I know perfectly well that during the entire period of operation, not a single lens has died a natural death. Over the years, only Nikon 50 / 1.4 broke down due to a blow (automatic focus was completely lost, I had to repair it twice, the information is in the review) and there was another case when I broke the stub and autofocus switches from a blow on Tamron 17-50 VC, when the lens continued to function normally. I have never had problems either with plastic mounts or with heavy use (and some lenses, like the flimsy Tamron 17-50 of the first version), I tormented very, very, very much. As my experience and the experience of my colleagues have shown - with lenses, or rather their performance - how lucky. Therefore, I don’t care about the Chinese assembly of this YN, it will work for half a year, and then it will most likely be sold to some amateur photographer who, believe me, will take no more than 1000 frames per year, from which the lens will be able to function for many years. The quality of the image, sadly, depends more on other factors than the lens and camera (I indicated this in detail here), optically given YN is good, more is not necessary.
                So it turns out that having knowledge, he can afford a wider and more deliberate choice of photographic equipment. Less experienced users (amateur photographers, housewives, sofa photographers) will be very intimidated by “Chinese build”, “unknown brand”, “exposure problems”, “focusing problems”, “durability” and “L-lens prestige” and possibly , will continue to sit with one Nikon D3100 / Canon 550D and a whale lens.
                Of course, this in no way applies to the professional and responsible direction of photography. Once again, we are talking about amateur photography and simple / not very complex photo tasks.

                b) to work with youngnuo flashes, especially with the cheapest ones, you have to get used to full manual control. The simplest youngnuo flashes do not have the automatic TTL modes that the SB-700/900 has. In this case, you can use a very cheap flash and get in the vast majority of cases 99% of the effect of SB-700/900. This is a great opportunity for a little money to significantly improve the quality of the photo, especially indoors. At the same time, the manual flash power control mode will give some not obvious advantages compared to SB-700/900. Also, some amateur photographers use cheap youngnuo manual flashes as pulsed light with umbrellas and boxes. For these purposes, there is generally no point in taking the original expensive flash. And so on and so forth.

                Many things are not obvious at first glance. And, of course, if there are funds, then there should be no alternatives with photographic equipment. But, if there is no money, or there is experience that allows optimal (rational and balanced) use of photographic equipment, then third-party manufacturers come to the rescue.

              • Garik N.

                Oh, I love the old sissy cameras from Nikon, from D100 to D200. Well, S5(s3)pro from Fuji too, of course...
                I’m also thinking about taking this Chinese lens for the D100...

              • Vitaly N

                It is possible that over time Yagi will achieve good quality, but simply added the ability to update firmware. They overdid too cheaply. But in flashes they use stepper motors. Tokina also uses conventional commutator motors, but they also have gearboxes with a large gear ratio, control of the movement of the helicoid as in the original Nikon. If I also decide to buy Yaga again, then only with the transition to FF. The crop is full of other lenses with the best price / quality ratio.

          • Vitaly N

            But I myself saw how the 35 on the younger D5100 simply refused to focus normally. And in amateur photography (I mean those who bought a DSLR so that it was and not deal with it) it is better not to use high-aperture lenses, and even capricious in focusing - there will be a lot of disappointments when viewing. The flash to the stock zoom is better.

        • Dmitry M.

          If you do not bombard the wedding, then these flashes will live long and will delight the lover. For prof. Goals need to take a flash with a larger resource.

  • Dmitry M.

    Thanks, great review.
    I bought myself 40 mm. two months ago with Ali, in conjunction with the D700 perfectly shows itself. 35 and 50 mm. as everyday glasses I’m not very comfortable, 40 mm. just right.
    Before After updating the firmware, it felt like focusing became a little faster.
    With the factory firmware, he focused very thoughtfully.

    • Valentine

      It seems that manufacturers make 40mm not as the middle between 35 and 50 (40s are almost 35s, but not fifty rubles at all), but from a technical point of view, to ensure the minimum size of the lens. Pancakes under EGF 40mm are enough on different systems. It is clear that the main advantage of the pancake is its small size, for which you have to pay with a decrease in the picture quality. So, I still don't really understand the point of buying this particular lens: its size is not much less than 35, the characteristics of aperture, vignetting and aberrations are worse, there are problems with metering, the price is the same. What are its advantages? After all, 35 is only 20 mm longer in size, but at the same time has a wider angle (if desired, it can be easily sprinkled up to an angle of 40 mm), better aperture (F2), no problems with metering, less vignetting and aberration.

      • Arkady Shapoval

        He's on the official website sfotkan on a super-telephony lens, which visually flattened it and made it look more like a pancake. Since Nikon does not have autofocus blinchers, it is designed specifically for "small size" / "compact lens".

      • Oleg

        It's just that in the case of the Kenon pancake, for example, if you reduce the focal length to 35 mm and increase the aperture to 2.0, you will get the classic 35 \ 2.0 price which is almost 2.5 times higher than the forty. And in order not to create competition within the system, then in fact there would be two thirty-five made the budget forty. Of the advantages of which compactness, a lower price, covers a full frame of the minuses, a truncated aperture and is not quite convenient on the crop

        • Valentine

          If it were possible to make 35mm with F2 and a good picture, but in the pancake format, do not hesitate, they would already have done it. The price for such a lens can be safely raised up from the usual 35-ki and it will be taken (because everything is the same, but light, small and flat). Still, I do not consider 40 mm an intermediate focal length between 35-50, but I think it is no longer 35 and far from 50. Therefore, a classic 35 pancake would have looked more advantageous than a compromise 40 mm. I suppose that making a classic 35-ku pancake with good quality is not so simple. With mediocre quality, you can probably make one.

            There may be a snag with retro focus. 40mm is the limit for such working segments, if the focal length is smaller, then the optical scheme is already changing to retro-focus, which is why you can’t make the lens a pancake.

            • Valentine

              Probably so, I'm not an optician, I am not saying anything. I just see full-frame pancakes Canon 40mm F2.8, Voigtlander ultron 40mm F2 and the like. Only on the basis of this, I believe that 40mm is more a technical limitation than the desire to give universal glass. For crop and mirrorless situations, the situation is slightly different, but there is also quite a lot of blunting from standard 35 and 50 towards about 40, and with a very large spread in picture quality.

                Konica 40 / 1.8 is still there - as a standard one was conceived for full-frame SLR film cameras. Both light and wide. But the modern ff does not get up because of the segment of the back small.

              It seems like canon has a 28mm pancake. True, not very.

              • Arkady Shapoval

                28mm there is no pancake, there is only a pancake under the crop Canon EF-S 24 / 2.8 STM

              • Valentine

                Yes, 24mm, which, taking into account the crop factor, is close to 40mm, but judging by the reviews and tests, it is not very successful. Very thin pancake Pentax SMC DA 40mm f / 2.8. Crop also has a lot of pancakes around 40mm, for example, Panasonic 20mm F1.7 (crop factor 2, F1.7 is impressive when most pancakes are F2.8). Pancakes with EGF 28 or 35, judging by the images, are compromising, apparently they are technically more difficult to make. There is vignetting, distortions, and aberrations, and the picture itself often loses to the forties.

              • Arkady Shapoval

                Panasonic 20mm F1.7 for mirrorless, with them a completely different story.

              • Valentine

                With aperture, yes, but the same 40mm equivalent with a minimum of distortion and vignetting is selected as the focal length. An accident? By the way (there is such a 2nd version), a fairly even picture, including edges, sharpness at a height. Those. from a technical point of view is good. The focal point itself is not very convenient, the artistic zest is also somehow lacking.

    A full-frame picture looks more voluminous. But distortions in the geometry of the face are more noticeable.

    thank you, very interesting review on this fruit ...

  • ashley

    Thanks Len!

  • Olga

    Hobby friends! Maybe someone has an electronic version of 4-hour video tutorials or a tutorial for the photographer, etc. If someone shares, thank you in advance! My email post office

    • Foreign land

      Rather, unfortunately here friends. And 4 hour lectures can really teach something?)

  • parent

    Respect Arkady for the photo with the Nikon D90 is wonderful! I have it, I don’t remember, about 7-10 years, and now I’ve taken it and am surprised at how good the machine is. Above 400 iso I do not get on it. Apparently gained experience. Well, not without your participation. Thanks.

  • ro

    Forgive me of course, but but you have the model ((

    • Valentine

      Discussing people in the pictures is not ethical. This blog is not about models.

    My lens did not focus on the 7000 series in live view, after the firmware it focuses and subjectively focusing became a little faster.
    I compare with 35 mm there are not so many differences in sharpness, it seems and sharper from the minuses, the aperture ratio is less for that big plus weight and dimensions

  • 300s

    I have been using Nikon D300s for about a week - the first couple of days without any complaints, exposure compensation + 1 ... + 1,3, with flash + 2,3 ... + 2,7. I updated the firmware, found no changes. After a couple of days, SUDDENLY it stupid constantly, in AF modes C or S it is almost impossible to focus on sharpness (I tried it at apertures up to 5,6). At all typical focusing distances (from 2-3 meters to infinity) in the viewfinder, I observe how the lens with a frequency of about 5 times / second crawls back and forth, skipping the plane of sharpness and not finding it (not from MDF to infinity, namely, crawling + / - as if 5-10 cm depending on the distance to the subject). Shooting - static: nature, parks. The descent can be kept pressed for at least 5 or 10 seconds - it crawls and that's it. Refocusing does not help, rarely, but the image shift is literally 1/10 of the frame, but this is not shooting, but the Kamasutra. Rare shots when you get there, 90% misses and soap. True, if you hit it, then to the sharpness and color rendition without any complaints. Immediately I put any other lens (35 1,8G for example and not only) - everything is clear and the first time. I am corresponding with an aliexpress seller, I want to return the money. Here's a Chinese lottery.

    It so happened that I had the opportunity to use all Yongnuo lenses. Added YouTube videos for all Yongnuo lenses (generations, lineups, etc.)
