It's important: Please note that the models of the Yongnuo YN50mm F1.8 lens, in versions for Nikon and Canon, look very different from each other. Typically, third-party lenses, such as Tokina, Tamron, Sigma, Carl Zeiss, etc., have a very similar housing design for versions for different systems.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

In short

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N) - very cheap fast half a ruble from the Chinese manufacturer Yongnuo Digital. The lens copied the original housing design Nikon 50 / 1.8G and optical properties Yongnuo Lens EF 50mm 1: 1.8. In general, he is not bad... First of all, Yongnuo YN50mm F1.8N is interesting to owners motorless Nikon cameras... For those who have a Nikon camera with a built-in focus motor, there is a wonderful and inexpensive Nikon 50 / 1.8D (as well as a million of its subversions).

The creative and practical potential of such a fifty dollars is difficult to overestimate. It is suitable for a wide range of photo tasks. Photo enthusiasts often use it as a portrait lens. Many just want a fast fix, in addition to their whale lens. So, f / 1.8 aperture more than three feet wider aperture of f / 5.6, which is used in 'dark' kit lenses at the long end. In numerical terms, this means that Yongnuo 50mm 1: 1.8 (YN50mm F1.8N) is approximately 10 times brighterthan, for example, whale Nikon 18-55 / 3.5-5.6which uses a maximum relative aperture of only 50: 1 over a 5.6 mm focal length. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: 5.6 * 5.6: 1.8: 1.8 = 9.679, which is rounded to the value '10'.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

History

The first lens from Yongnuo Digital is fifty dollars for Canon EOS cameras - Yongnuo Lens EF 50mm 1: 1.8 (YN50mm F1.8) introduced December 27, 2014.

July 10, 2015 in Shanghai was represented version Yongnuo AF-S 50mm 1: 1.8 (AF-S 50mm 1.8, for Nikon cameras). The lens was labeled 'AF-S' and the depth of field was F / 22. Near the thread for the light filter was the inscription 'YONGNUO AF-S 50mm 1.8', near the depth of field scale was the inscription 'AF-S 50mm 1: 1.8'.

On May 7, 2016, the 'YONGNUO Ø58mm YN50mm F1.8' lens went on sale (without the 'AF-S' lettering, without the 'N' lettering and with the depth of field scale for f / 16). Most likely Yongnuo AF-S 50mm 1: 1.8 was just a prototype, its optical design and type of focusing motor will remain unknown.

Some time later, the letter 'N' was added to the lens name - YONGNUO Ø58mm YN50mm F1.8N... 'N' is short for 'Nikon ', after which the lens took the form shown in this review.

On May 14, 2018, an updated version for Canon cameras was presented - Yongnuo Lens 50mm 1: 1.8 II (model YN50mm F1.8II). After 2 weeks, on May 30, 2018, a faster version for Canon cameras was announced - Yongnuo Lens 50mm 1: 1.4 (model YN50mm F1.4). August 18, 2018 was introduced YONGNUO YN50mm F1.4N E.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

Main technical characteristics of YONGNUO 50mm 1: 1.8 (YN50mm F1.8N):

For some reason, on the network, I met very little information directly about the fifty dollars from Yongnuo for Nikon cameras, because in this review I tried to add as much useful information as possible on the YN50mm F1.8N.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

Assembly

The lens came to me for review almost new. Before sending it for review, the owner used it for only a few days.

In a small box is a warranty card, instructions in Chinese and English, and the lens itself with a front (YN-58) and a back cover. The box is made in the colors typical of the golden boxes of Nikon Nikkor lenses. What the copy from this review did not have was a protective film on the front and rear lenses, which originally comes with the lens.

The lens is well assembled. It's nice that, unlike the version Yongnuo Lens EF 50mm 1: 1.8The Yongnuo YN50mm F1.8N version has a 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.

Of the shortcomings I want to highlight:

• The focus ring has a slight backlash.
• If you press the diaphragm lead (the tab for controlling the diaphragm) from the bayonet side, it will be noticeable that the aperture blades not only close / open but also move back and forth towards the front or rear lens. In other lenses, I did not observe such a looseness of the aperture mechanism. I can’t tell how critical this behavior of the diaphragm mechanism is. During real photography, I did not have any problems with the aperture. True, there are rumors in the network that the diaphragm mechanism is a weak link in this lens.
• Yongnuo YN50mm F1.8N weighs 20 grams heavier than the original Nikon 50 / 1.8G, from which the case design was copied (185 vs 203 grams). However, in my hands I got another new Yongnuo YN50mm F1.8N, made at the end of 2018 and its weight is 177 grams.
• Also, it's a pity that I didn't find a hood in the package. At the same time, some Yongnuo YN50mm F1.8N lenses come with a plastic bayonet type hood. It is not known why not all YN50mm F1.8N lenses are equipped with a hood.
• Several times during high-speed continuous shooting, the camera lost contact with the lens. To restore performance, it was necessary to disconnect the lens and reinstall it on the camera. This situation occurred several times on different cameras, which indicates a problem with the lens, not the camera.
• Unlike Nikon 50 / 1.8GThe Yongnuo YN50mm F1.8N is not dust- and waterproof rubber lens mount seal.
• There is no inscription about the country of manufacture on the lens case. Of course, we all know very well that the lens is made in China, but still the lack of information on the product itself only adds to the alarm.

The diameter of the front filter is 58 mm, the same diameter uses Nikon 50 / 1.8G and many other lenses.

I want to note that the Yongnuo YN50mm F1.8N (for Nikon cameras) is better made than Yongnuo Lens EF 50mm 1: 1.8 (for Canon cameras). Unlike the version for Canon cameras, it uses a metal lens mount, virtually internal focusing, has a window with a focusing distance, the depth of field scale, a more elaborate AF / MF switch and can use a bayonet type hood.

UPDATE 1: With some cameras and some instances of the Yongnuo YN50mm F1.8N, the access to the memory card indicator blinks when turned off. Most likely the camera constantly 'disconnects / connects' the lens. The exact cause is unknown.

UPDATE 2: With some cameras, the battery power decreases when turned off.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

Focusing

The lens has built-in focus motor DC-type (DDirectly Current Motor- ordinary DC motor). To be precise, the Yongnuo YN50mm F1.8N 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. Strange, but the noise level is much lower than the lens Yongnuo Lens EF 50mm 1: 1.8. It is very good that the Yongnuo YN50mm F1.8N noise is less than non-motor Nikon 50 / 1.8D. Sorry, but low noise from the ultrasonic motor Nikon 50 / 1.8G he does not compare.

Auto focusing on the lens is enough fast. Auto focus speed comparable to Nikon 50 / 1.8G.

When used on a camera Nikon D90 (with unpretentious Multi-CAM 1000 focusing system), as well as on the camera Nikon D70 (with super-simple Multi-CAM 900 focusing system), the lens behaves well, rarely focuses incorrectly. I had no problems with focus accuracy and focus. I was pleasantly surprised by the quality of the focus. On camera Nikon D90 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.

I have a lot of experience with the lens Nikon 50 / 1.8D. I want to note that, nevertheless, the Yongnuo YN50mm F1.8N focuses in the general case not as confidently as the original lens.

When focusing, the front lens group moves in the middle of the frame of the housing. I can’t say that the lens has internal focus. But 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. This type of focusing can also be found in Nikon 50 / 1.8G и Nikon 50 / 1.4G.

The focus ring is rubberized and rotates approximately 80 degrees. When extreme positions are reached, the ring abuts. The focus distance scale rotates in the opposite direction to the rotation of the focus ring (I see this for the first time!). Manual aiming is not very convenient. During manual focusing, you can hear 'plastic rubbing against plastic'.

The lens barrel has an 'AF / MF' (auto focus / manual focus) focus mode switch. During autofocus, the focus ring remains stationary and can be freely rotated 360 degrees without affecting focus.

The lens has a window with a focus distance scale in meters and feet, as well as a depth of field scale for F / 16. The minimum focusing distance is 45 cm, and the maximum magnification ratio is 1: 6.7 (typical for similar fifty dollars).

Other features:

1. Yongnuo YN50mm F1.8N has no focus problems in Live View (tested on Nikon D90).
2. The lens transmits the focus distance to the subject in the camera (analog Nikon D, Nikon G).
3. Yongnuo YN50mm F1.8N has a slightly pronounced 'Focus Breathing' effect (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.
4. The viewing angle of the Yongnuo YN50mm F1.8N is slightly wider than that of Nikon 50 / 1.8D. It may seem that the focal length of the Yongnuo YN50mm F1.8N is closer to 45 mm.
5. Focusing is performed by simultaneously moving the entire lens block (all lenses) relative to the focal plane.
6. Yongnuo YN50mm F1.8N 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.
7. Important: YN50mm F1.8N has a small focus-shift (shift-focus). During aperture, the exact focus moves away from the lens. The level of shift is the same as that of Nikon 50 / 1.8D.
8. Important: Yongnuo YN50mm F1.8N 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.
9. Important: I have already met on the net that the Yongnuo YN50mm F1.8N does not automatically focus with some Nikon cameras. And also I met information that the Yongnuo YN50mm F1.8N may suffer from a strong twitching of focus. Obvious problems are observed with the model Nikon D300s.
10. Important: this instance suffers from front focus on the camera Nikon D40, which is used by the owner of this lens (according to the owner).
11. Unknown compatibility with teleconverters.
12. Unknown compatibility with adapter FT-1 for Nikon 1 system cameras.

To summarize, then the lens is focused with focusand the clever design of the housing and 'AF / MF' switch make the YN50mm F1.8N more convenient to use than Nikon 50 / 1.8D.

Yongnuo 50mm 1: 1.8 (YN50mm F1.8N)

Image quality

The color rendering is pleasant, in some ways even better than the original Nikon 50 / 1.8D. Also, I want to note that enlightenment in versions Yongnuo Lens EF 50mm 1: 1.8 and Yongnuo 50mm 1: 1.8 (YN50mm F1.8N) visually very different. Most likely the version for Nikon uses updated enlightenment.

Chromatic aberration was not without. Friging (green and purple contours of contrasting objects in the blur zone, example).

In the center of the frame, the lens is sharp enough already at F / 1.8. Confident sharpness in the center of the frame comes with F / 2.2-F / 2.5. At f / 2.8 aperture, the lens in the center of the frame is very good. On full-format cameras, there will most likely be a noticeable subsidence of sharpness at the corners and edges of the image.

The vignetting level on APS-C cameras is low even at F / 1.8. I did not have a 58 mm filter on hand to check how much it could affect vignetting.

The level of distortion is small.

The lens well tolerates back and side light. The deep-set front lens contributes to this. The frame of the case works like a small hood. In rare cases, you can get a slight rainbow stratification of the rays and small glare. With an optional bayonet hood installed, backlit and side-light operation should improve. From bright objects to achieve the effect of a 14-ray star pretty hard. Due to the rounded petals, the effect occurs only on strongly covered diaphragms (example), while the formed star is not very beautiful and poorly expressed.

I want to separately highlight in bold, which is optically YN50mm F1.8N no worse than the original Nikon 50 / 1.8D. Laboratory tests may even show the superiority of the YN50mm F1.8N. True, modern Nikon cameras can automatically correct some flaws. Nikon 50 / 1.8Dsuch as vignetting, distortion, chromatic aberration etc., in the case of the YN50mm F1.8N, third-party software (or not) must be used to remove distortion.

On open apertures, the bokeh of the lens is no different Nikon 50 / 1.8D и Canon 50 / 1.8 II. The reason for this the same similar optical design. Below is a GIF animation of the optical circuit for six of these lenses:

Optical schemes of lenses: YONGNUO LENS EF 50mm 1: 1.8, Yongnuo YN50mm F1.8N (from review), Canon Lens EF 50mm 1: 1.8, Canon Lens EF 50mm 1: 1.8 II, Canon Lens EF 50mm 1: 18 STM, Nikon 50mm 1: 1.8D AF Nikkor

Enlightenment of the front lens of the Yongnuo 50mm 1: 1.8 lens (YN50mm F1.8N)

My experience

A cheap fifty for Nikon non-motorized cameras is very good. Motorized camera owners could always afford to buy a pretty one Nikon 50 / 1.8D for only 90-110 dollars. But for owners of non-motorized cameras had to buy a more expensive Nikon 50 / 1.8G (170-200 dollars). With the advent of Yongnuo 50mm 1: 1.8, you can afford a brand new fifty dollars with an integrated focus motor for $ 80.

I relate to the YN50mm F1.8N quite warmly and am glad that amateurs have the opportunity to cheaply buy a high-aperture fifty. I'm also glad that the YN50mm F1.8N turned out to be better overall than Yongnuo Lens EF 50mm 1: 1.8. It’s only a pity that the Nikon version costs half the price of the Canon version.

Important: This lens is primarily intended for amateur photographers (not professionals or advanced amateurs!) who will be careful about their photo equipment and not use it in conditions with a heavy load (weddings, reports, extreme conditions, etc.). I saw with my own eyes how my colleague, during a lens change, dropped Nikon 50 / 1.8D from a meter height onto a concrete floor. The lens received only a tiny scratch on the body, but this did not affect its functionality. I don't think the Yongnuo 50mm 1: 1.8 will stand up to this test.

Of course, the stress resistance of Yongnuo 50mm 1: 1.8 is not comparable to the old manual lenses Nippon Kogaku Japan Nikkor-S Auto 1: 2 f = 5cm or Nikon Nikkor-SC Auto 1: 1.4 f = 50mm, or MS Helios-81H 2/50... However, for most tasks, I would have preferred the presence of autofocus in front of a sturdy, quality body. Users who are looking towards the YN50mm F1.8N are often strapped for funds and faced with a choice: 'This Chinese' or 'Japanese manual'? In personal messages I am very often asked this question. Usually I give the answer that for photography in general it is better to "Chinese", and for video shooting (where automatic focus is not so important) - any "Japanese manual".

If to summarize completely all my experience with the lens, here is my brief recommendation: YN50mm F1.8N can be safely bought for Nikon non-motorized cameras (exact list here) For cameras with built-in focus motor (exact list here) it is better to take the original Nikon 50 / 1.8D (does not matter, used or new).

All Nikon 50 / 1.8 Autofocus Lenses

1. Nikon 50mm 1: 1.8 AF Nikkor (first version, MKI) - the lens was produced only in Japan from 1986 to 1990. It is easy to distinguish by a window with a focusing distance and a narrow plastic focus ring. There are two subversions that are no different:
   • MKI first subversion. Weighing 210 grams. It is easy to distinguish by the screw under the inscription '1: 1.8'. From September 1986 to March 1987. Serial numbers start at 2
   • MKI second version. Weighing 165 grams. It is easy to distinguish by the absence of a screw under the inscription '1: 1.8'. From 1987 to 1990. Serial numbers start at 3.
2. Nikon 50mm 1: 1.8 AF Nikkor (second version, MKII, also known as the 'N', or the 'NEW' version) - the lens was produced in Japan and China. The MK II version was produced from 1990 to 2001. There are three subversions that are no different:
   
   • MIJ (MADE IN JAPAN)
   • NJ (NIKON JAPAN)
   • MIC (MADE IN CHINA)
3. Nikon 50mm 1: 1.8D AF Nikkor (third version, MKIIIbetter known as 'D'-version) - the lens is available from 2002 to this day. All lenses are made in China.
4. Nikon AF-S Nikkor 50mm 1: 1.8G SWM Aspherical (fourth version, MKIVbetter known as '1.8 G'-version or '1.8 AF-S' version) - the lens has been produced since 2011, all lenses are made in China.
5. Nikon AF-S Nikkor 50mm 1: 1.8G SWM Aspherical Special Edition (fifth version, MKVbetter known as version 'Special Edition' or 'SE' or version for the camera with a retro design of the case Nikon Df) - the lens has been available since the fall of 2013. All lenses are made in China.
6. Nikon Nikkor Z 50mm 1: 1.8 S, from summer 2018, lens for mirrorless cameras with Nikon Z mount... Diagram of 12 elements in 9 groups, 2 ED, 2 ASP.

Details on the lineup of fifty dollars from Nikon can be found in my article 'All Nikon autofocus fifty dollars'.

I want to note that the MKI, MKII, MKII versions use the same 6/5 optical circuitry, similar to the YN50mm F1.8N.

Versions MKIV, MKV use the updated optical scheme 7/6.

Differences from Nikon 50 / 1.8G

The main differences between Yongnuo 50mm 1: 1.8 (YN50mm F1.8N) and Nikon AF-S Nikkor 50mm 1: 1.8G SWM Aspherical:

• YN50mm F1.8N is a newer lens introduced 5 years after the release Nikon 50 / 1.8G.
• YN50mm F1.8N is 18 grams heavier Nikon 50 / 1.8G. The YN50mm F1.8N does not come with an integrated hood.
• У Nikon 50 / 1.8G Yes rubber lens mount sealwhich makes the mount mounts dustproof and waterproof.
• Lenses use different focus motors. YN50mm F1.8N uses a conventional micro motor, Nikon 50 / 1.8G uses a Nikon SWM ultrasonic motor. The focusing speed is practically the same.
• Nikon 50 / 1.8G has the ability to constantly manually control the focusM / A'. For manual focusing, YN50mm F1.8N must be set to the 'MF' position.
• Different optical schemes. Nikon 50 / 1.8G uses a more modern optical scheme, including one aspherical element, which allows to achieve better image, especially on open diaphragms.
• Modern Nikon cameras can automatically correct some lens distortion Nikon 50 / 1.8G. With the YN50mm F1.8N, some image enhancement functions will not be available, since this lens is not in the memory of modern cameras.
• Cost of new Nikon 50 / 1.8G about 2-3 times the cost of the new YN50mm F1.8N.

Differences from Nikon 50 / 1.8D

The main differences between Yongnuo 50mm 1: 1.8 (YN50mm F1.8N) and Nikon 50mm 1: 1.8D AF Nikkor:

• YN50mm F1.8N is a newer lens introduced 14 years after the release Nikon 50 / 1.8D.
• Lenses use a completely different body design. Visually Nikon 50 / 1.8D much smaller YN50mm F1.8N.

Results

Yongnuo 50mm 1:1.8 (YN50mm F1.8N) – cheap analog Nikon 50 / 1.8G (only about 100 dollars from this link) is optically close to Nikon 50 / 1.8D. No matter how strange it sounds, the YN50mm F1.8N is a perfectly suitable lens. Given the price / performance ratio, I recommend it to all amateur photographers who want to join the world of fast auto focus lenses.
