In this review, I will call the lens YONGNUO YN35mm F1.4 abbreviated Yongnuo 35 / 1.4.

YONGNUO YN35mm F1.4

YONGNUO YN35mm F1.4

In short

Yongnuo 35 / 1.4 is a fast wide-angle lens from Yongnuo for Canon cameras. Heavy, well-built, and most importantly, with decent image quality. It has a low price tag and is a very attractive solution for amateur photographers.

Main review spoiler: yes, at F / 1.4 the lens can be used. For undemanding tasks, Yongnuo 35 / 1.4 is generally a godsend.

Yongnuo 35 / 1.4 is the cheapest autofocus 35-bit with f / 1.4 for full-frame DSLR cameras (at the time of this review). Usually all lenses with a 35mm focal length with an aperture ratio of 1: 1.4 are professional solutions. Making a fast wide-angle lens for DSLR cameras is never easy.

On full-frame cameras, the Yongnuo 35 / 1.4 is a wide-angle lens with a very wide range of applications. On cropped cameras, the Yongnuo 35 / 1.4 acts as a standard lens (in terms of focal length) and its scope is also very wide.

Assembly

The lens came to the review completely new.

In a small box is a warranty card, instructions in Chinese and English, a card with a manufacturing date of 15-10-2018, a desiccant and the lens itself with a front (Yongnuo LC-67) and a back cover. The covers are made of thick plastic. The front and rear lenses of the lens are initially covered with special transport films of blue color.

In general, the lens is well assembled. Yongnuo 35 / 1.4 has metal mount mount. The focus ring is very wide and rubberized, tactilely pleasant. The main body is made of metal. The thread for the filters is also metal. It is stated that the contacts of the microprocessor are gold-plated.

The weight of the Yongnuo 35 / 1.4 lens itself is 810 grams and more than 900 grams with protective caps and hood. In the hands, the lens feels like a solid thing. The lens weighs more than the TOP original Canon 35 / 1.4L II.

The design of the Yongnuo 35 / 1.4 is reminiscent of other similar modern lenses such as Canon 35 / 1.4L II or Sigma 35 / 1.4 ART. The red ring looks and feels - metal, shimmers with light as if it is chromed. In photographs, the ring seems to be just a colored strip, but in a lively visual perception of the ring has a slightly different effect. Perhaps this ring should refer to Canon L-series professional lenses, for example Canon 35 / 1.4L II.

Diaphragm consists of 7 petals and form a hole in the shape of a regular heptagon, while in the photographs in the blur zone rather round discs of blur appear in the range F / 1.4-F / 2.2.

The lens has a USB port in the lower rear of the lens (in the bayonet area). The port serves to update the firmware (described in detail about this in the relevant chapter) The USB port does not have a rubber plug.

The package comes with excellent metal hood labeled LH-73T. The hood is made of thick metal, very pleasant to the touch. The hood fits into special slots near the front lens of the objective (bayonet type hood), it can also be installed in the opposite direction for transportation. There are white dots for installation. The hood fits nicely and very securely. I was surprised that the manufacturer spared no expense in creating such a hood and included it in the package, especially considering the fact that all other Yongnuo lenses that I reviewed before the Yongnuo 35 / 1.4 came without a hood initially.

Due to the fact that the hood and part of the body are metal, during shooting in cold weather in the open air, the fingers of my left hand constantly froze, with which I usually support the lens from below, mainly behind the hood.

The Yongnuo 35 / 1.4 does not have a rubber mount and is not an all-weather lens.

Focusing

For focusing, Yongnuo 35 / 1.4 uses micro motor and is an analog of Canon MM (Micro Motor). Auto focus will work with any SLR camera Canon EOS. Most likely, mirrorless cameras with an appropriate adapter should not have any special problems.

Focus speed average (closer to low), significantly lower than the original lens Canon 35 / 1.4L II.

At a photo shoot with a moving child in the open air, 2/3 of the pictures were with focusing errors due to insufficient focusing speed. UPDATED: this problem was cured in a modernized model Yongnuo 35mm 1: 1.4C DF UWM

Auto focus noisybut the noise level is much lower than that of Yongnuo 50 / 1.4. When shooting a video using auto focus and a microphone built into the camera, noise will be heard on the video. UPDATED: the noise was healed in the modernized model Yongnuo 35mm 1: 1.4C DF UWM

I worked with the lens on the camera Canon EOS 5D с simple 9-point focusing system. Focusing tenacity is low. Focusing errors are unsystematic and are often associated with low depth of field at F / 1.4.

At leisurely street and studio photo shoots using Canon EOS 5D about a third of the shots had obvious focus errors. On unhurried reports from the baptism of a child, weddings and weddings, more than a third of the images were with obvious focus errors. When shooting stationary objects (architecture, landscape), there were practically no focusing errors.

UPDATED

On camera Canon EOS 750D (aka Canon Digital Rebel T6i, aka Canon Kiss Digital X8i) from 19-point advanced focusing system and the Hybrid CMOS AF III system for focusing in Live View, the tenacity of the focus is significantly better than that of Canon EOS 5Dbut still there are more focus errors than you might expect. Focusing errors are unsystematic, but spoil the impression of the lens.

On camera Canon EOS 750D I checked the presence of the back and focus front at different focusing distances (infinity and MDF as well). The shots taken using the Live View mode (which theoretically does not suffer from back / front focus) were used as a measure. Focusing accuracy using phase focusing sensors, both central and side, completely coincided with the Live View mode (several series of shots were taken, the best result was chosen). On camera Canon EOS 750D all focus modes in Live View work well, including focus with automatic face detection.

Focusing ring rubberized, wide, in manual focus mode rotates approximately 135 degrees (3/8 of a full 360 degree revolution). When the extreme positions are reached, the ring does not rest, but continues to rotate slowly. It is convenient to aim manually. During manual focusing, a small annoying sound is heard as 'plastic rubbing against plastic or metal', while the ring rotates smoothly and quite pleasantly. During focus direction change, there is small lag (delay), but it does not cause much discomfort.

There is a 'AF-MF' (auto focus / manual focus) mode switch on the lens body. During auto focus focus ring remains stationarywhile it can be freely rotated 360 degrees without any effect on focusing. Unfortunately, unlike many original Canon lenses, Yongnuo 35 / 1.4 does not support Canon FTM (or similar) manual focus control.

Lens has internal focus, the front lens remains stationary during focusing. Focusing occurs due to the movement of the rear lens group, the effect of dust suction by this movement is minimal. You can use different kinds of filters without any problems.

The minimum focusing distance is 35 cm, while the maximum magnification for macro photography of 1: 6.67 can be obtained.

The lens has a window with a distance scale with marks in meters and feet. The scale is small, on it there are marks for 2, 1, 0.6, 0.4, 0.35 meters and a label of 'infinity'. There is also a label with the depth of field scale, but only for the value of F / 22. There is no tag for working in the infrared spectrum.

Other focusing features:

  1. on the distance scale, the focus ring has a slight 'overrun for infinity'. Yongnuo 35 / 1.4 does not have a hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens at infinity under any external temperature conditions. For accurate aiming at infinity, you cannot just bring the focus ring to its extreme position.
  2. Focus shift (shift-focus) is missing.
  3. Yongnuo 35 / 1.4 has a small 'Focus Breathing' effect (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.
  4. The lens sometimes continues to focus for a short time after the focus activation button has been depressed (usually by half-pressing the shutter button). This happens if the lens is not focused accurately enough (the lens somehow continues to focus when the focus button has already been released). Not everyone will notice this feature and it does not particularly interfere with comfortable work with the lens.
  5. Teleconverter compatibility unknown
  6. Adapter compatibility unknown Canon mount adapter EF-EOS M for using optics with a bayonet mount Canon EF/Ef-s on cameras with a bayonet mount Canon EOS M
  7. Unknown compatibility with Canon Mount Adapters EF-EOS R for use with mount optics Canon EF/Ef-s on cameras with a bayonet mount Canon EOS RF
  8. Most likely, some cameras will have to fine tune the focus to avoid back / front focus

Important: Yongnuo 35 / 1.4 - a lens from a third-party manufacturer. It may happen that it will not work correctly with some Canon cameras.

USB firmware update

On the lens housing Yongnuo 35 / 1.4 there is a USB port with which you can update the lens software (firmware / firmware). Unfortunately, the functionality of the YNLensTool Updater Version 1.00 program, which is responsible for working with the lens, is very meager. You can only see the current firmware version and update it to a new one. Firmware versions can usually be found on the official website, but firmware for Yongnuo 35 / 1.4 has not yet been released (at the time of creation of the review).

A widespread USB 2.0 MICRO-B port (regular Micro-USB, like many mobile phones) is used for connecting to the lens. A USB cable is not included. To connect, I used a USB cable for my old android phone. My lens had basic firmware V1.01.

Yongnuo 35 / 1.4 firmware version and YNLensTool Updater Version 1.00 program window view

Yongnuo 35 / 1.4 firmware version and YNLensTool Updater Version 1.00 program window view

A firmware update, most likely, allows you to improve the compatibility of the lens with new cameras, improve the autofocus, eliminates some other errors. I appreciated the usefulness of this function when working with the lens Yongnuo 100mm 1: 2  for Nikon cameras. But still it’s very bad that there is no way to roll back (restore) the original firmware that came out of the box.

To upgrade the firmware (software) of the lens:

  1. Turn off the camera, detach the lens
  2. Open program YNLens Updater for updating (program for Window or MacOs can be downloaded on the official website here)
  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 finish
  6. Disconnect the cable, attach the lens to the camera and start shooting

Image quality

As for an inexpensive lens, the Yongnuo 35 / 1.4 shows quite acceptable image quality.

Sharpness

  1. in the center of the frame at F / 1.4, the lens shows acceptable sharpness
  2. there is a noticeable drop in sharpness to the edges of the frame at f / 1.4
  3. great resolution in the center of the frame on covered apertures after F / 2
  4.  resolution at the edges of the frame returns to normal on covered apertures after F / 4
  5. high contrast

It is difficult for the lens to show a high-quality result at F / 1.4 on a 24MP cropped camera, but after F / 1.8 everything gets much better.

Distortion

  1. barrel-shaped distortion
  2. the overall level of distortion is at a level typical for such lenses
  3. the nature of the distortion is complex, it will be a little difficult to correct in the editor

Vignetting

  1. noticeable vignetting is strongest at F / 1.4-F / 2
  2. vignetting decreases with focus towards the MDF. Most noticeable when focusing at infinity
  3. on APS-C cameras, vignetting practically disappears at F / 2.0-F / 2.8
  4. vignetting is easily fixable in the editor

Aberration

  1. open diaphragms have a moderate amount of chromatic aberration
  2. the strongest chromatic aberration visible at the edges and corners of the image
  3. general level HA is at the level typical for high-quality similar lenses
  4. there is moderate friging (HA in the blur zone)
  5. I did not notice blooming in any of the pictures

Rest

  1. on covered diaphragms you can achieve a beautiful effect of a 14-ray star
  2. the lens is good, and sometimes very well tolerates backlight. In rare cases, you can get a looped arc from a bright light source
  3. lateral contrast may be noticeably lost, the hood partially eliminates the problem
  4. diaphragm forms fairly smooth discs of blur only in the range of F / 1.4-F / 2.2, at values ​​of F / 2.2-F / 22 you can clearly trace the regular polygons from point light sources in the blur zone
  5. color rendering is neutral, pleasant
  6. the bokeh is fairly flat, but the discs of confusion have concentric onion circles (only from bright light sources), and the discs of confusion have roughness

Important: at the time of the creation of this review, there was no Yongnuo 35 / 1.4 profile for popular RAW converters. But I noticed that for Yongnuo 50 / 1.8 lenses under Nikon / Canon, as well as for Yongnuo 35 / 2.0 under Canon, lens profiles for the latest versions of Adobe Camera Raw and Adobe Lightroom have already appeared, therefore, most likely, the appearance of a lens profile for Yongnuo 35 /1.4 is only a matter of time.

If you use a 35 / 1.4 lens in full frame, then to achieve the same image on a camera with an APS-C sensor with Kf = 1.6x (on Canon EOS cropped cameras), you need to use a lens with a focal length of about 22 mm and a relative aperture of 1: 0.93. But, as you know, such lenses, especially with autofocus, have not yet been released. Thoughts on this subject are stated here.

Full frame sample photos

All sample photos in the gallery below were shot using a camera Canon EOS 5D and the Yongnuo 35 / 1.4 lens. Photos taken using RAW ('.CR2') file conversion with Canon original utility Digital Photo Pprofessional 4 (Canon DPP) without any changes (without treatment), or immediately in camera JPEG. All photographs were taken using a lens hood and without using filters.

'JPEG' source photos can be download from this link (more than 200 different photos, 1.4 GB). RAW source photos ('.CR2') can be downloaded at this link.

UPDATED. More photos on Canon EOS 5D.


UPDATE Sample photos on crop

All sample photos in the gallery below were shot using a camera Canon EOS 750D (aka Canon Digital Rebel T6i, aka Canon Kiss Digital X8i) and a Yongnuo 35 / 1.4 lens without a hood. Photos taken using RAW ('.CR2') file conversion with Canon original utility Digital Photo Pprofessional 4 (Canon DPP) During the shooting, I did not notice that I used everywhere white balance 'flash', and some of the photos were taken with the aspect ratio of 16: 9, so I had to tweak the RAW a little to get an acceptable picture.

Let me remind you that the pixel density of Canon EOS 750D 20% higher than fifty megapixel Canon EOS 5Dsr/Canon EOS 5DS.

Original RAW ('.CR2') photos can be download from this link.

Photos in reduced size galleries, resize up to 2048 X 1535 pixels (about 3.1 MP) were made using the free software FastStone Photo Resizer 3.1. Data was imprinted at the bottom of the photos. EXIF (excerptdiaphragm, ISO). When reducing the size of photos, I use the quality of 70-80% of the original. This percentage of quality is more than enough to transfer all the details in the photo without overweight in the 'JPEG'. With 3 MP, you can print photos up to A4 without any problems. The light weight of the photos allows you to quickly view sample photos for general acquaintance with the capabilities of the lens and allows you to save photo loading time and disk space on my site. When viewing photos on the display of different devices, the site automatically adjusts the photos to the size of the device used. To view a 1: 1 photo pixel by pixel, just open it in a new browser tab, do it as easy as clicking on the photo thumbnail with the middle mouse button (by scrolling) or using the 'open link in a new tab / window' context menu.

My experience

I shot about 35 (updated) shots on Yongnuo 1.4 / 25.000 in a wide variety of settings, from wedding photography to architecture photography. During all this time, no emergency situations with him were noticed. However, doing a little bit of reportage shooting with the Yongnuo 35 / 1.4 seemed to me a difficult task due to the insufficient focusing speed. At the same time, a lot of good material came out.

35mm at f / 1.4 is already a 'serious' lens. If autofocus performance is improved in subsequent firmware updates, it will be a very good lens. But, most likely, it will not be possible to completely heal the speed and tenacity of focusing.

UPDATED: still cured in a modernized model Yongnuo 35mm 1: 1.4C DF UWM

If the focusing of the Yongnuo 35 / 1.4 was at least roughly the same as the old Tamron or Sigma or Tokina lenses, the Yongnuo 35 / 1.4 could become a very popular lens.

In my previous reviews of Yongnuo lenses, I have compared Yongnuo lenses to their original counterparts. In this review, I will not compare the Yongnuo 35 / 1.4 with the original Canon 35 / 1.4L II since the latter is a completely different class of optics, aimed at professional everyday activities, not allowing failures under any circumstances. With the Yongnuo 35 / 1.4, during a responsible shooting, you still have to hope that he does not refuse and does not miss with focus. At the same time, the Yongnuo 35 / 1.4 is a tasty morsel for amateur photographers who have heard about the grandiose possibilities of the 35 / 1.4 optics.

In general Sigma 35 / 1.4 ART will be better than Yongnuo 35 / 1.4. But personally, I would stick with the Yongnuo 35 / 1.4 due to its low cost and not much worse picture.

Yongnuo 35 / 1.4 was very pleased with its capabilities at F / 1.4. It's a pity, but there are still a number of questions about focusing.

The Yongnuo 35 / 1.4 will be of interest to many amateur photographers who use full-frame cameras. Optical quality and build quality are decent. And if you remember about the price tag, then the Yongnuo 35 / 1.4 can become a massive 'especially high-speed thirty-five'.

Advantages

  1. low cost (about 350 dollars for the new Yongnuo 35 / 1.4) This is the cheapest 35 / 1.4 class full-frame autofocus lens
  2. high aperture
  3. its own optical design. The optical design uses aspherical and anomalous dispersion elements
  4. USB port for firmware upgrade
  5. Convenient manual focusing, focus ring rotates 135 degrees
  6. there is a window with a scale of focusing distances
  7. internal focus
  8. fixed focus ring during auto focus
  9. good build quality: metal bayonet mount, most of the body is metal, reliable and comfortable covers, gold-plated processor contacts
  10. robust bayonet-type metal hood included in delivery
  11. depth of field scale, no focus shift
  12. seven-petal diaphragm
  13. nice / neutral drawing that can be used as a nice artistic trick during certain types of shooting
  14. good sharpness starting at f / 1.4 in the center of the frame. Moderate level of basic optical distortion (aberration, vignettingdistortion)

Disadvantages

  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. large weight (810 grams for Yongnuo 35 / 1.4 versus 580 grams for Canon 35 / 1.4L)
  3. average focusing speed, closer to slow, significantly lower than Canon 35 / 1.4L II
  4. the usual micro focus motor and, as a result, the lack of the function of constant manual focus control similar to, for example, the FTM mode Canon 35 / 1.4L II
  5. slight noise from the focus motor
  6. unsystematic focus errors
  7. rubbing sound / sensation during manual focus
  8. focus ring lag during manual focus when changing direction of rotation
  9. there is no basic dust and moisture protection (for example, Canon 35 / 1.4L II there is a rubber mount seal)
  10. slight effect of 'Focus Breathing' (decrease in viewing angle during focusing towards MDF)
  11. hole aperture at values ​​F / 2.2-F / 22 it is poorly rounded and is a regular heptagon
  12. there is no tag for working in the infrared spectrum, the depth of field and focusing distances are small
  13. there is incompatibility with some cameras and / or teleconverters (no exact data)
  14. lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of optical distortion (distortionvignetting etc.)
  15. lack of a lens profile in popular RAW converters (temporary drawback, you can create a profile yourself or wait for its release)
  16. the survivability of this lens and the variation in quality are unknown. Little information on Yongnuo Certified Lens Service Centers
  17. certain imperfections inherent in similar lenses

UPDATED

At the end of July 2019, the lens was announced on the official website YONGNUO YN35mm F1.4C DF UWM.

  • Nick

    Has anyone, except the author of the review, bought this lens? What is your opinion?

  • Alexey

    And how much better is this lens compared to the YN35 / 2? Is there any significant difference?

    • Arkady Shapoval

      Much, the difference is significant.

  • Novel

    I'd rather take my own 35/2 IS - size, weight plus stub is more interesting to me personally. You can also understand 14 / 2.8 - very specific optics for rare use, you can take some pampering. But 35mm is such a focal point that either will become a favorite, or will not be used at all. There are too many potential problems for a beloved glass, and too high a price for a very rarely used glass with many compromises.

    Although the yongs stubbornly improve product quality, they inevitably turn up the price tag. And it’s already not bad. I suspect that they will occupy the niche of Canon and Nikon on old mounts as they shift towards mirrorless ones.

  • Yumir

    Thanks for the review! It was interesting and useful to read and get acquainted with the characteristics of glass.

  • anonym

    Thank you very much for your review! I chose Canon 35 2.0, the price is not much higher, but more reliable and with a guarantee! The price is overpriced IMHO - 2 times, I would buy for playing no more than 150-200 USD

  • Alexander

    Hello. I bought this glass a couple of weeks ago for 21300 with some kind of discounts or coupons. Before him there was yn 35 2.0 ... but through an adapter to sony a7-2. Now there is no Sonya and took it under canon 5d. The bunch is very good, the balance is excellent. No stabilizer needed. In general, I am satisfied with the glass. At 1.4 miracles should not be expected, as, for example, from 50 1.4 sigma art (sharp from 1.4), but the color and bokeh were not pleasant. A Chinese person conveys colors more correctly, but I feel that this glass needs another carcass, 5 dm2 or m3. Focusing is certainly slower than, for example, 50 1.4 usm. I can't say anything bad about the lens. Now there is also a nikon system and maybe I will take 35 1.4 or 2.0 for it. All good photos.

  • Yura

    I saw photos of a lens with an N sticker for Nikon, but they are not available for sale ... ..can tell me where to find it?

    • Arkady Shapoval

      35 / 1.4 for Nikon does not exist

      • Igor

        Not, like me, a decent lens. I liked the way he draws and F1.4 even really nothing !!!

    • Vitaly N

      You saw a photo of the prototype from the exhibition, not yet on sale.

  • Yura

    It's a pity it is written a couple of months after the exhibition will be on sale for more than 3 months

  • Igor

    Arkady, in my opinion the lens is not bad enough for that price, but you need to wait until the version for Nikon comes out!

  • koba

    Somewhere in the comments I wrote that after Viltox, all Chinese manufacturers will probably start installing ultrasonic motors in their autofocus lenses, and they immediately mastered the production of stepless motors. By the way, such motors are many times easier to manufacture, they are very simple and even primitive in design. And they have all the advantages for modern production - cheap to manufacture, efficient to operate and short-lived, in fact, you can make them break soon after the expiration of the warranty period. So they waited and today Yongnuo presented this lens (so far only for Canon) with an ultrasonic motor, and its designation exactly coincides with the motor that Viltrox installed in its 85 / 1.8 (and which was highly praised by Christopher Frost). Now, of course, the edged Chinese will not wait years, as the Japanese do, in order to rip more bobbles, and for sure soon we will see an update to all autofocus lenses with the same motors, but they will also make some technical improvements in the design and even in the optics. I also foresee the emergence of autofocus lenses from the wonderful Chinese manufacturer Laowa, maybe from others. Sony's company has made great progress, as it provides under an official license the specifications of its mount and communication with the camera, Nikon and Kenon are just sick of this option, so more and more good and cheap lenses will appear specifically for Sony, and Nikon and Kenon will wonder why their mirrorless systems constantly undersold ... Cheap and high quality Chinese lenses with ultrasonic motors are almost death for Nikon and Kenon, of course, in the future, not now. Now imagine that one fine day the same Youngnuo or Laowa buys Tamron, and then Pentax or ... This is so, for fantasy, but in China not such fantasies have come true yet ...

    • B. R. P.

      “Cheap and high quality Chinese lenses” are either one or the other. As soon as Chinese lenses take the first step towards quality, they cease to be cheap. Moreover, in terms of optics, they are still very far from the average representatives of Nikon, Canon, etc.

      • koba

        At half the price, for example, the Laowa 105 mm SFT lens, as shown by numerous tests, surpasses almost all similar and not similar lenses in the world. And they have very unique things that have no analogues. This industry is not new there, but now the process of becoming at a new level, in new economic conditions, and everything is possible along this path. The price here is always determined by the older brothers. The same Laowa is free to sell the same lens much cheaper, but does not see analogues, so it puts the price at $ 600. Production is not an abstract thing, if there are conditions, then everything can be cheapened without loss of quality, and even with the addition of quality. The myth of the high cost of all the good has been actively promoted for 200 years now, and of course it has objective reasons, only in China they approach this issue within reasonable limits, and wherever possible, they cheapen it, they started to produce optical glass, and it began exported in huge quantities, and you know which country ranks first in this export? Guess? They reduced its cost by almost 8 times, without reducing quality, but what is it, glass is glass, if produced according to recipes and technologies, it will be exactly the same even on Pluto. And the cost of glass in lenses is about 40% of the cost (in complex and large - and even 60%). It remains to produce special grades of glass, which China has also mastered literally in the last few years. So, by reducing the cost of components, you can maintain quality at a low cost. The monopolists of the market (and the photo market is essentially monopolized by 3-5 companies) also constantly reduce the cost of their products, but only to increase their profits, the reduction in cost does not affect the retail prices of products, here Chinese and other Japanese see and find their niches manufacturers. There is also such an effect - some users always stand on the side of manufacturers, as if they are getting some kind of income from them, usually such people are almost always snobs, the main thing for them is to hold branded products in their hands, this is like a Mercedes to emphasize their importance, superiority before others, not so rich. And also sometimes, here and on other forums, representatives of the manufacturers themselves, or their dealers "work very intensively" ... If you filter out such commentators, then the part that will always be interested in getting quality products for a normal fee will remain, by the way, this is the lens , I even consider it a little overpriced, if it costs around $ 250 (new with an ultrasonic motor), then it would become available to many ordinary users, not just commercial ones, who should essentially share their income with Kenon or Nikon for such super expensive goods. Again: for example, the Nikon 24-70 / 2.8G (an excellent lens that even had technical flaws and broke, here you have super expensive things!), Was released in a circulation of about 900000 copies. Stand there, and now you can buy a new one, about $ 1400. If it were produced in large quantities, not with a draconian wrap for the pros, and assembled in China, with the technical modifications that Nikon introduced in it in the last 2 years of its production, then it could well cost around $ 700, and in In that case, many advanced amateurs could buy it, and its shooting galleries would amount to several million ... Is that bad? But, of course, the manufacturing company would not have made huge profits, for which, in fact, they all produce.

        • B. R. P.

          A very correct, interesting and versatile analysis of the situation. Unfortunately, world-class brands are deeply addicted to superprofits and are unlikely to want (and cannot) get off of it. We can only hope that this cup will bypass the Chinese manufacturers ...

        • Ruslan

          I completely agree that people have become too obsessed with brands that actively use it, releasing second-rate products at inflated prices. If there is active technical progress in society, as they say about it at every corner, then the development of technologies should lead to a decrease in the cost of one or another technical process and, as a result, to reduce the cost of products and make them more accessible to the end consumer - in practice, everything happens the other way around ... At the same time, the products are becoming less and less quality (no one wants to stop the conveyor). But oh well, it's offtopic.
          As regards the lens, judging by the test photos and the fact that Arkady has already shot 25000 frames for them, the lens is quite worthy even for such a price. Over time, it will become cheaper when the yongs make a replacement for ultrasonic motors. We are waiting for the version on Nikon, it usually comes out a little better with them than on Canon.

        • Alexey

          Laughing at night looking with cheap and high-quality Chinese lenses🤣
          It's okay that Chinese smartphones are already more expensive than an iPhone and a google pixel, and with each new firmware they become more and more buggy. Look at the dxOmark rating paid by the Chinese, where xiomi with a crazy distortion in the main camera module leads by a large margin, even Huawei with optics from a watering can overtook it.
          The price of 1400 $ will not confuse you in a smartphone with such photo capabilities? And this is a brand that did not take above $ 500 for a top smartphone before !!! The Huavey had the same beads. Doesn't the word marketing tell you anything? As soon as the Chinese earn a name, the price will skyrocket!

          • Dmitry Kostin

            "It's okay that Chinese smartphones are already more expensive than iPhones."
            Which absolutely does not mean that they are really taken for such grandmother in the rest of the normal world. For people who earn several thousand $ a month, I have not seen other phones except the Samsung S series or iPhones (these same people used to go with Nokia when she was Finnish and on Symbian). Any Huawei Mate RS Porsche Design is a product for the Chinese market, because there are a lot of rich people (just ask how many Ferrari, Rolls-Royce, Bentley, Tesla, Lamborghini are sold there). These same Chinese comrades are also among the main consumers of Leica cameras. It's just that the dudes have a lot of money, and they don't hold on (hello to Dima Medvedev), and they no longer work there for a cup of tea.
            How DxOMark began to churn out reviews of kitaphones (many even before the official release on sale on raw firmware) 5 years ago already aroused certain suspicions. Then, many times they changed their rating, or rather the method of calculating it, on their website.

          • Victor

            "It's okay that Chinese smartphones are already more expensive than an iPhone and a Google pixel, and with each new firmware they become more and more buggy."

            I have been using rn7 for the third year already, nothing is buggy, everything is still flying, despite the difficult life of a smartphone, a competitor from Samsung (not to mention a stub) nervously smokes on the sidelines for a price, chyadnt? By the way, the sales of the starred couple are gradually falling, what would it be for?)

            The Chinese have to finish the AF in the lenses, and the quality of the optics has already become almost equal to the masters.

            • Aleksey68

              The Chinese, and not only they, will never finish AF in optics for obvious reasons.

              • Victor

                So far, the most controversial AF is with the Chinese, so I think they have something to work on.

            • Aleksey68

              but they cannot do it. and sigma / tamron will not be able to either. “The protocols of the Elders of Zion” are to blame :)

          • Novel

            Since this is so unloved by fans of communist China and old scoops of markets, he habitually decides, and instead of snickering Chinese will come out not snickering, with a phone price of less than $ 500.

            And you habitually confuse cause and effect. You should not be offended by the Chinese, who raise the prices of their products as their quality grows, but by those thanks to whom $ 1000 for a top-end smartphone is an unaffordable price for you. Well, for yourself. In the end, you always have an alternative - not to use expensive items. And cheap smartphones in five years will provide you with the same features of five years ago for the same price.

            • Alexey

              For Roman: And you habitually confuse cause and effect. You should not be offended by the Chinese, who raise the prices of their products as their quality grows, but by those thanks to whom $ 1000 for a top-end smartphone is an unaffordable price for you. Well, for yourself.

              As if radically disagree with you. Before the birth of the child, a photo from a smart was enough, after birth I bought the Xiaomi Mi 10 Pro, vaunted at that time by the dxOmark rating,
              looking at the twisted faces in the photo, I realized that it was from the evil one.
              After shooting a night landscape in cloudy weather on manual settings with a resolution of 108MP and a shutter speed of 20 seconds. I discovered a strikingly starry sky, and after a month of using the phone, I returned it to the store through the service center, having managed to prove that the photo matrix is ​​all in dead pixels, on the machine all this is retouched programmatically.
              Having spat on the search for the perfect camera in the mobile, I bought a Canon M50 and a used Sigma 18-35mm f / 1.8 via an adapter. Just in the amount of a smartphone :) Now a frequenter of sites for the selection of optics. I am looking for an “ideal” option for me for walks and travel, light high-aperture, with a large supply of focal lengths.
              But I realized that one glass cannot do with my requests.

              • Victor

                Awesome.
                The man discovered that the shirik on the smartphone is not quite suitable for shooting faces, and the fact that the smartphone, in principle, is not intended for shooting night landscapes, none, but of course the Chinese are to blame for everything (and who else) :-D

                L - logic

              • Alexey

                For Victor nouname.
                Of course, no one shoots landscapes and full-length portraits at 28mm, and the camera was installed in the smartphone in vain, it is unnecessary there, you probably have a Nokia 1100?

              • Victor

                For Alexey nouname.
                Of course, because 28mm on the camera does not distort the picture in portraits at all, and the instructions for each top-end smartphone necessarily indicate the possibility of silent night photography at a 20-second exposure. And of course, the Chinese are to blame for everything))) That's right, I didn't mess anything up?
                The head has to be not only for eating.

              • Alexey

                You are of course right, the Chinese are not to blame for this, Samsung sells rejected matrices to them, the Chinese are not yet so developed technologies to produce their own photo matrices ... Or can you name a Chinese manufacturer of photo matrices?
                And at the expense of distortion in optics, so Huawei with the help of the "Chinese" Leica means Xiomi in full.

              • Alexey

                If you have a head not only for what to eat, then name the Chinese manufacturer of photo matrices, and if you cannot, then you should not carry your fingers across the screen of Redmi note 7. First, save money for instructions for this phone. And find there a point where it is forbidden to take portraits and night landscapes.

              • Victor

                Well, of course, the Chinese only buy rejection, but how could it be otherwise?

                I bet your keyboard manual doesn't say anything about not pounding yourself over the head with it either. Actually, why not, check it out somehow in practice.

              • Victor

                If the keyboard is damaged, you can also try to hand it over to the store through the service center. Fortunately, there is experience.

              • Alexey

                Judging by the lack of a logical chain in your comments, you have a head. And looking at the resentment, the spitting-out shop assistant was returning the money for Hlaomi. Do you still pay for the phone I used? Go sell doors, maybe it will work out better, the photo technique is not for you🤣🤣🤣

              • Novel

                And I recently installed new doors for myself, just in the amount of a smartphone. So this new children did not appear, otherwise I would uh ...

              • Alexey

                The main thing is not to use Chinese condoms, otherwise you will have to sell the last doors.

              • Andrei

                Roman, are the doors not Chinese at least?

              • Novel

                The film under the concrete on them is Korean. It seems to be.

              • Victor

                Roman, until a month has passed, try to do one thing - go to the door and, in turn, tell each of them the magic phrase: “Sim-sim, open up!”. It did not work for me, in the end I handed the doors back through the service center, having managed to prove that the doors did not work as indicated in the instructions.
                Any surprises can be expected from Korean film.

              • Victor

                Your extreme comment speaks for itself)

                There is nothing to add.

              • Victor

                You, Alexey, perhaps start by learning the basics of the language in which you are trying to express yourself. Once you've mastered this, move on to the basics of photography, capturing the basics of logic along the way. As soon as your level at least slightly rises above the zero level that is currently taking place, come and talk on more complex topics.

              • Novel

                Victor, I tried to use the interroom as an entrance and balcony, but it didn't work out, so I have to complain to the manufacturer and return it, yes. But I'm still in search of that one - one door to close them all.

              • Maks

                My dear fellow made the wrong door? A section of cheap Chinese peepholes in door hardware. On this site, the photo technique is discussed!

  • Alexander

    Hello everyone. A few examples from this glass:https://flic.kr/s/aHsmHRaoYP

    • Arkady Shapoval

      and how is it for you on 7d?

      • Alexander

        On 7d it is super after 5d. Misses certainly happen, but not a lot. for dynamics, it generally fits my surprise. You don’t even need a tracking mode. clicked and immediately shot. I am satisfied. And I would not say that this glass is directly very much inferior to sigma art. Sigma of course is less sharp misses less, but the background washes better .. sigma bokeh is not at all :)

        • Aiman

          Hi, I am interested in buying the new Yongnuo 35mm 1: 1.4C DF UWM. How did you find this lens?? Is the focusing fast and accurate? Post some pics if you have this new lens.

    • Denis

      what is it all so yellow? well i understand that leaves but anyway

      • Alexander

        Yellow :) I still don’t really know how to handle equalizer .. do the right exposure ... and the colors in the kenon are not the best .. I’m waiting for an adapter from a young man to test Sony FF :)

        • Denis

          it is believed that canon has the best colors
          Have you tried branded fixes?
          immediately want to take 85 Chinese. but canon has a good 85mm 1.8, and is cheap

          • Alexander

            I will not argue about the color. There were different systems. Brand fixes kenon were, 50 1.4,85 1.8. 85 is a very good glass. But for the price of a new 85 Chinese, it is fashionable to find only strongly used ones. native. In general, the taste and color ...

        • Roman

          What a loud statement about the best colors :) If you mess with the white balance, the colors everywhere will be “not the best”.

          • Michael

            I would not say that there bb is badly mowed

  • Alexander

    if they make 85 1.4, then most likely I’ll take it :) The Chinese amateur photographer fully met his expectations :)

  • Alexander

    Arkady,
    I don’t hear anything about the glasses from Yungi under FE SONY?

    • Arkady Shapoval

      Nothing at all, but the other day here on Radozhiv there will be a review of Yongnuo 42.5 / 1.7 under Mikru.

      • Alexander

        very interesting :) There are still rumors that they are doing their camera with the EF buttonhole :)

        • Arkady Shapoval

          They made it and are already selling it in China, but only at their Chinese sites. EF mount, and the sensor is from Micra, and the camera itself is on Android

        • Roman

          YN450. We wait. I hope she also knows how to use EF-S, because if not, it doesn't make much sense.

        • Roman

          https://zhuanlan.zhihu.com/p/84345523 - this is not a bad review. In Chinese, but the translation into English is very clear.

  • Alexander

    Hello everyone. I added three photos from this glass from the canon 1D mark II camera to the same album:https://flic.kr/s/aHsmHRaoYP
    About the work of this bundle ... the grip is comfortable, works quickly, but not always accurately in burst mode and with tracking focus. There is a lot of soap at long distances, but apparently it is necessary to adjust the focus somehow, if it is, of course, in 1D m2. The pattern and color of course differ from 5D and 7D, but the volume is closer to 5D, apparently due to crop 1.3. In general, the picture is pleasant at open f1.4. On the sony a7r, nothing good came out. through its own yongnuo EF-E II adapter, this glass worked very slowly and did not want to twist the handles after the nimble 7D.

  • Alexander

    Well, I threw one with canon 5d. suddenly who will be interested to compare the result from different cameras.

  • Alexander

    Hello.
    I tried yn 35 1.4 on canon 5d mark 3. This is a scribe ... the focusing speed seems to be the same, but with a hit even at the central point, everything is sad. When adjusting +20, FF still remains. If you clamp down to 4-5.6, then it is already tolerable. Through life view, everything is perfectly sharp at f1.4. But on canon 7d, I introduced a -3 correction and hits right on target :) These are the pies ..

  • Evgeny Petruchok

    Hello Arkady and readers! Share your opinion! I have a fotik Kenon 5d first, I look at him 17-40mm f4. After reading the reviews I became at a crossroads: take this El zoom or yongnou 35 1.4, then dig up and buy over and above from Samyang or yongnou?
    I use photo equipment as an amateur, for leisurely filming. In this or that case I understand about the sacrifice of universality and aperture, it is the picture quality that interests me. Thanks!

    • Oleg

      I will only say about focal lengths - 35 mm and 17 mm - a very big difference. These lenses will not replace one another. You need to think and understand which subjects are your priority now - those for which you need 35 mm precisely at a well-open aperture, or a wide angle. If 35 mm by 1,4, 1,8 scenes are not that priority, take 17-40, and you will have the same 35 mm only with f4. In extreme cases, you can buy a more affordable 35-ku from Yongnuo with f2.

        Thanks for the answer! Now I’m thinking of taking 17-40 f16 + Yongnou 28 2.8 instead of 35-2.0 Tokin. There must be a good kit) Have you encountered Tokinamt?

          Personally, I would take 17-40. If these are two options.

          For the super-wide, and even at the full frame, 2.8 is not particularly significant - when focusing on close objects, you can play with blurring the background at 4.0, and anyway, such as 1.8, for example, there will be no effect.

          Plus, this is one lens. Native. Workhorse. And not two, of which one is not bad, and the second is very mediocre. Better by 17-40 buy later the same yongu, but 50 / 1.8. 17-40 will be a universal landscape-architectural-marching-group portrait (especially with a tripod, if landscape is important, and with a polar). Plus a street photo, there you will push up to 4 anyway. And 50 - universal aperture with entry into the portrait area.

            Thanks for the detailed answer! I will do so!

    At kenon itself, 70d. I switched to YN from manual samyang 35 1.4, I was satisfied. Not a professional, I rent for myself and sometimes I load something on the drains.
    With firmware version 1.0 it works with serious failures, but already firmware version 1.04 is fine. It doesn’t focus very well on the open through the viewfinder, but in liveview with focusing on the face everything is fine (I understand, maybe I didn’t figure it out).
    After the first connection to yusb, the plastic cracked (see photo). The profile for CR has already been released.
    Slightly behind image quality from my last 35s, but not critical.
    For me, as an amateur, further on the list are some pluses.

    It just so happens that I have used almost all Yongnuo lenses. Added YouTube videos for all Yongnuo lenses (generations, lineups, etc.) https://youtu.be/AfQ76sAwIac
