In this review, I will refer to the Yongnuo YnLens YN35mm F2R DF DSM for short. YN 35 / 2R... Firmware version of lens used V1.06 for 29.07.2021.

Here on the site there is already a review of the lens Yongnuo 35mm 1: 2 DF DSM S for cameras with mount Sony E... This review will largely repeat review of the lens for Sony E / FE mount... Main differences between versions ''S'and' R ':

  1. different date of announcement, version 'R' is one year newer
  2. the 'R' version has an 'O' shaped rubber protective seal for bayonetthat didn’t have 'S'versions
  3. version 'S' It has programmable button 'Fn', this button has been removed from the 'R' version
  4. the 'R' version has a slightly different design body, there is a dark brown strip on the side of the bayonet, imitating the design Genuine Canon RF Lenses
  5. the 'R' version has a problem with an awkward lens hood. The hood is now fixed very smoothly and nicely
  6. in the 'R' version, the diaphragm works quietly and without lag
  7. version 'R' has certain features focus / control rings
  8. the 'R' version focuses a little faster
  9. the 'R' version is slightly more expensive

In short

The YN 35 / 2R is the second lens from Yongnuo (Ynlens) for Canon mirrorless cameras with a full-frame sensor and RF mount (the first was Yongnuo Ynlens YN85mm F1.8R DF DSMreleased a couple of months earlier).

The YN 35 / 2R is a medium wide angle lens for full frame mirrorless cameras. It has fast internal autofocus and is very quiet thanks to the focusing motor. Optically good enough, in the center of the frame is sharp already from F / 2 (without any reservations), only perceptible chromatic aberration make themselves felt.

YN 35 / 2R is lightweight and compact enough. The YN 35 / 2R is designed to compete with the original lens Canon LENS RF 35mm F1.8 MACRO IS STM.

All autofocus 35mm full-frame prime lenses for Canon RF

YN 35 / 2R can be used as a replacement for other similar lenses. Below I have prepared list of all autofocus full-frame lenses with Canon RF mount and 35mm focal length:

  1. Canon LENS RF 35mm F1.8 MACRO IS STM, about 500 USD
  2. Yongnuo YnLens YN35mm F2R DF DSM (from this review), about 400 USD

The list is made up of two models. Canon's RF mount system is still quite new and very few exist for it. autofocus solutions (for 2021). But Canon RF system cameras will also work well with Canon EF mount lenses mounted through the appropriate adapter Canon EF -> Canon RF.

Below is a list of all autofocus lenses for Canon EF mount 35mm full frame DSLR cameras.

  1. Canon LENS EF 35mm 1: 2, about 170 USD
  2. Canon LENS EF 35mm 1: 2 IS USM, about 550 USD

Yongnuo YnLens YN35mm F2R DF DSM


The lens was officially announced in July 2021.

YN 35 / 2R is second lens from Yongnuo for Canon full-frame mirrorless system with Canon RF mount. The first was Yongnuo Ynlens YN85mm F1.8R DF DSMpresented in May of the same year.

YN 35 / 2R is built on the basis of YN 35 / 2S, which was announced October 23 2020.

Very important: YN 35 / 2R has nothing to do with lenses Yongnuo 35mm 1: 2 (for Nikon F mount SLR cameras) and Yongnuo 35mm 1: 2 for DSLR cameras for Canon EF mount. YN 35 / 2R belongs to the new line of Yongnuo lenses Ynlens and is built on a completely different optical scheme.

In general, YN 35 / 2R is an alternative to the original Canon LENS RF 35mm F1.8 MACRO IS STM... True, the latter has much broader functionality. That only is the built-in image stabilizer and the possibility of macro shooting.

Yongnuo YnLens YN35mm F2R DF DSM

Yongnuo YnLens YN35mm F2R DF DSM


The lens came to the review completely new.

The small box contained a warranty card, instructions in Chinese and English, a quality control card, a desiccant, bags, a hood and the lens itself with front and back covers. The covers are made of dense plastic. In the box, the lens is secured with two durable foam clips. The box itself is initially sealed in a protective film.

'YnLens 35mm' lettering on lens barrel engraved.

YN 35 / 2R has metal mount. Stated that microprocessor contacts gilded... The focusing ring is wide, rubberized. The lens feels good in the hands. On the side of the rear lens there is a light-cutting hood that prevents excess flare and light scattering.

On the side of the bayonet there is an 'O'-shaped protective rubber mount seal.

The YN 35 / 2R weighs just under 300 grams.

On heavily covered apertures, the aperture has the shape of an irregular heptagon. The diaphragm consists of 7 blades.

There is a bayonet mount mark on the body and a mark for quick installation of the hood. The lens uses a plastic hood LH-54T, which must be fixed in special grooves located near the front lens of the lens. The hood can be set in transport mode with the reverse side, but in this position, access to the focusing ring is almost completely lost.

The lens has a connector on its body USB TYPE C for connection to a computer (see the corresponding section below in the text). The port is closed with a tight rubber plug.

The focus ring can be programmed through the camera menu.

It's important: during intense reportage shooting on a completely new Canon EOS RP the YnLens 35mm lens went into 'MF' mode (according to the camera) several times on its own and did not respond to the control / focus ring and did not respond to the AF / MF switch. In this case, it was possible to control the aperture from the camera. Turning off the camera, removing and reinstalling the lens solved the problem. On the same camera, there was no such problem with the YnLens 85 / 1.8R. Perhaps new firmware will correct the situation. UPDATE: The same thing happens on the Canon EOS RP and Canon EOS R6.

For focusing, the YN 35 / 2R uses stepper focus motor DSM (Digital Stepping Motor). Auto focus should work with all Canon RF mount cameras.

The focusing speed is high (closer to very high), quite comfortable for work. On camera Canon EOS RP I didn't have much focusing problems. After the lens has lost precise focusing, refocusing is performed very quickly. Focusing on the face and eyes on Canon EOS RP works very well. In general, a bunch Canon EOS RP + YN 35 / 2R works almost perfectly. Only a few times the lens did not want to focus on objects located in the 'infinity' region.

It's important: In difficult shooting conditions, as well as when shooting dynamic scenes, the focusing quality with the YN 35 / 2R can be noticeably worse than with similar original lenses, such as Canon RF 35 / 1.8 MACRO IS STM... Most likely, even in simple shooting conditions, the autofocus tenacity with the YN 35 / 2R will very much depend on the camera used. Perhaps over time, new lens firmware will improve the behavior of the YN 35 / 2R.

Auto focus very quiet... When shooting a video using autofocus and the built-in microphone in the camera, the resulting video noise from the built-in focusing motor is not audible at all.

Lens uses electronic focus ring... The focusing ring is rubberized, wide. Manual aiming is enough conveniently... The focus ring rotates easily. I did not observe any lag (lag) when changing the direction of rotation. The focus ring makes a faint sound of two plastic parts rubbing during manual focusing.

It's important: in the camera menu Canon EOS RP  you can set the parameter “MF focusing ring sensitivity of RF lenses"

  1. Depends on rotation speed
  2. Depends on the angle of rotation

The function is in the section: 'C. Fn III: Advanced -> 4 Feel. focus. ring. MF vol. RF '. This feature is very useful and I'm glad the Canon RF system has introduced it.

It's important: You can change the direction of rotation of the focusing ring. The function is in the 'C. Fn III: Advanced -> 3 Focus Focus Rotation rings'. It will be useful for those users who are accustomed to different directions of rotation of the focusing ring (for example, when using other systems, such as Nikon F / Z).

On the case there is a focus mode switch MF / AF.

Very important: In 'AF' mode, the focus ring of the YN 35 / 2R lens can be additional control ring functionstypical of original lenses Canon rf. Camera Canon EOS RP allows you to set the following functions to this ring:

  1. Aperture change (while holding down the metering activation button exposure or without)
  2. Change excerpts (while holding the metering activation button exposure or without)
  3. Setting the ISO sensitivity (while holding down the metering activation button exposure or without)
  4. Compensation exposure (while holding the metering activation button exposure or without)
  5. Do not use

During auto focus focus ring remains stationary.

Critical: to use the function FTM (Full Time Manual Focusing - permanent manual focusing control), the additional control ring should be programmed to “Do not use at all”, and in the SHOOT8 menu (red menu color) for the 'Manual electr. focus 'select' Single -> on 'or' Single -> on. (enlarge) '. If you set any value other than “Do not use at all”, then while rotating the focusing ring, the focusing distance and the selected parameter (ISO, or excerpt, or aperture, or shift exposure). An unpleasant little thing, but it can be easily removed by a competent setting.

The lens has internal focusing, the front and rear lenses remain stationary during focusing. It is possible to use various filters without any problems.

The closest focusing distance is 35 cm, while the maximum magnification for close-up photography is 1: 7.7, which is the usual value for such a lens.

'Focus Breathing' effect (changes in viewing angle during focusing) small and almost invisible.

There are no useful marks on the focusing distance, depth of field, or anything else on the lens.

Focus shift (shift-focus) was not noticed during operation and testing.

Firmware Upgrade

The YN 35 / 2R lens barrel has a USB port through which you can update the software (firmware / firmware) of the lens. For YN 35 / 2R you need to use utility, which immediately carries a new firmware.

The functionality of the service utility for the YN 35 / 2R, which is responsible for working with the lens, is very scarce. You can only view the current firmware version and update it to a new one. I found this utility for YN 35 / 2R here и here. There is a utility version only for the latest Windows operating systems.

The lens uses the common USB 2.0 TYPE C port for connection (many mobile phones use this one). The package does not include a USB cable. To connect, I used a USB cable for my android phone and updated the firmware without any problems. The procedure took less than 5 seconds.

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

Important: To update the lens firmware (software):

  • Turn off the camera, remove the battery from it, detach the lens
  • Launch the program YN35mm F / 2.0R DF DSM FM UPDATER
  • Attach the lens to the computer using a USB cable. If everything went well, the program will automatically detect the connected lens
  • Click [UPDATE] to start updating. Wait until the end of the update. The [NoNeed] button also updates the firmware, but says that this is not necessary (the latest firmware is already used). What the 'EnableControl' checkbox does is still unknown
  • Disconnect cable
  • Attach the lens to the camera
  • Insert the battery into the camera
  • Turn on the camera

Image quality

YN 35 / 2R handles the sensor easily Canon EOS RP by 26 MP.

Optically, this is a fairly good lens, of the obvious shortcomings - only chromatic aberration and sagging sharpness in the far corners of the frame.


  • good sharpness at an open aperture in the center of the frame, F / 2 in the center of the frame is fully 'working'
  • very good resolution in the center of the frame is achieved at f / 2.8-f / 4
  • there is a noticeable drop in sharpness in the far corners of the frame
  • resolution in the corners of the frame reaches a good level only at closed apertures in the area of ​​f / 8
  • low coma, even at F / 2
  • the lens is optimized more for working at medium to long focusing distances. Detail sags a little at close focusing distances


  • distortion moderate, pincushion
  • the nature of distortion is unified, easily corrected in the editor
  • it is difficult to notice distortion in the pictures


  • vignetting is most pronounced on F / 2 and focusing on infinity
  • vignetting decreases with focus towards MDF
  • vignetting almost disappears at values ​​after f / 5.6


  • the lens creates a sufficiently large number of chromatic aberrations, both longitudinal and transverse
  • there is a noticeable frigging (the color of the contrasting areas of confusion is green and purple), the frigging is significantly reduced with aperture
  • most chromatic aberrations are observed at the periphery of the frame


  • the effect of the rays of the star is poorly expressed (14 rays)
  • Blur disks are uneven on tightly covered diaphragms
  • the lens works very well in backlight, only in the most difficult conditions you can get flare that spoils the picture
  • the discs of confusion have bulbous concentric circles due to the aspherical element

So far, there is no profile for this lens in popular RAW converters. Firmware Canon EOS RP does not automatically correct some types of distortion (in fact, everything except diffraction). The camera indicates that it does not have the required data for this lens.

My experience

Acknowledgements: I want to express my special gratitude to the photographer Alexander Bozhkevich (Instagram) who provided a brand new camera Canon EOS RP (zero mileage) to create this overview.

The YN 35 / 2R is no different from modern high-quality similar lenses.

I am glad that the YN 35 / 2R uses a modern optical design with internal focusing and a large number of special optical elements.

Price YN 35 / 2R not very lowThis is most likely due to the fact that there are very, very few different lens models for Canon RF. If the price tag for YN 35 / 2R is comparable to the version Yongnuo 35 / 2S for Sony E / FE, then I can safely recommend YN 35 / 2R for purchase.

I shot two shots with the YN 35 / 2R with a total volume of about 3000 frames and was completely satisfied with the capabilities of the lens.

Important: YN 35 / 2R has several times fewer minor and not particularly minor problems than Yongnuo 35mm 1: 2 for DSLR cameras with Nikon F mount and Yongnuo 35mm 1: 2 for DSLR cameras with Canon EF mount. I filmed practical for all lens models from Yongnuo (more than 20 models at the time of this review) and I can say with confidence that new mirrorless solutions from Yongnuo head and shoulders above their older mirror counterparts.

You can watch the video on my channel by this linkor below:


The YN 35 / 2R is a high-quality modern lens for Canon EOS R full-frame mirrorless cameras (RF mount). May serve as an alternative to other similar lenses. The image quality is generally quite high. Most likely, the price of a lens will eventually drop to a similar solution from Yongnuo for a bayonet mount Sony E... If this happens, the YN 35 / 2R will have a very good price-performance ratio.

10 main advantages:

  1. light weight, compact dimensions (filter diameter only 52 mm)
  2. good build, metal bayonet, bayonet seal, bayonet hood included
  3. focusing stepping motor, fast and quiet
  4. internal focusing, fixed focus ring during auto focus
  5. electronic focus ring, continuous manual focus control, AF / MF switch, very weak Focus Breathing effect
  6. focus ring can take over the functions of an additional control ring
  7. USB port for firmware upgrade
  8. four special elements in the optical scheme (low dispersion, aspherical and 2 high refractive index)
  9. good sharpness in the center of the frame already with F / 2
  10. the lens handles shooting well against bright light sources

10 main disadvantages:

  1. aperture 24% lower than the original Canon RF 35 / 1.8 MACRO IS STM
  2. on heavily covered apertures, the aperture has the shape of an irregular heptagon
  3. no built-in image stabilizer (for example, it has Canon RF 35 / 1.8 MACRO IS STM и Canon EF 35/2 IS USM)
  4. there is no additional control ring (for example, there is Canon RF 35 / 1.8 MACRO IS STM)
  5. in a very rare case, the focus ring can cause a conflict (see the overview section 'focusing' -> block 'critical')
  6. in rare cases, the lens will forcibly switch to 'MF' mode (buggy)
  7. software options for working with the lens via the USB port are very limited
  8. lack of data about the lens in modern cameras and converters, which makes it difficult to automatically correct some types of distortion
  9. YN 35 / 2S version for Sony E / FE had an additional programmable button, which was removed from the Canon RF version
  10. strong vignetting at open apertures, palpable chromatic aberration

Comments: 24, on the topic: Review of Yongnuo YnLens YN35mm F2R DF DSM (for Canon RF)

  • B. R. P.

    Thanks for your review. Yes, the difference in price with the native 35 is not yet in favor of the Chinese. Excuse me for the trivial question, can you expect a review / impression on the Canon RP?

    • Arkady Shapoval

      I'll do it. I still need to finish the review for 85 / 1.8. Overall, I find RP to be one of the best budget full frame options.

      • B. R. P.

        Thanks, Arkady.

  • Dmitriy

    The review on the lens is good, but it would be much more interesting to read the review on the camera.

  • in

    For 200 bucks you need to take, but for 400 it makes no sense. Add another hundred and take a native macro with a stub

  • Gregor_S

    Finally the sources with RP

  • Seladir

    Doubt between RP and 90D - prices are similar. That is, the full frame is against a more advanced camera in all respects: video capabilities, matrix autofocus, battery, focus stacking. It seems that the latter is better for macro and landscapes.

    • Victor

      Everything is exactly the opposite.

      Exactly the same sensor-type autofocus is available in the RP. Video (4k) at 90d no, solid soap. And you will not find sharp optics capable of resolving all 32.5MP (zooms, for sure), otherwise, according to the picture, the rp will certainly skip 90d in no time. Except what to take only for macro, but why exactly 90d in macro?

      • Seladir

        Matrix autofocus is not quite the same there. For example, the RP lacks eye tracking AF. The RP has very limited 4K video - strong crop, only contrast AF.
        This matrix is ​​valuable for me, first of all, DD, improved tolerance to pulling out shadows or underexposed images. I also use the modern EF-S 18-135 USM, which should be designed for 24MP matrix, and with 32.5MP the difference is already small when viewed from the side. In general, the resolution of optics is not something discrete and with a clear ceiling. Rather, the profit from additional megapixels will decrease the further, the stronger. It can be represented as a kind of function that starts as a linear f (x) = x, and then turns into a characteristic logarithmic curve. And I still do not think that this is already the matrix resolution where the profit is near zero.
        Also, I don't think RP will have any advantage at low ISOs. It is possible that up to a certain threshold, more megapixels from a smaller sensor will produce more detail.
        I now use 60D - I really like it, but I still want a modern camera in terms of the matrix, AF sensor, video capabilities.
        There is a set of EF-S / EF lenses, so I gravitate towards the same system.

        • Victor

          I have already dropped a picture here with 18-135usm and 90d, I can drop it again - look, what kind of porridge is there https://live.staticflickr.com/65535/50241167266_83bc6339fe_o.jpg

          This is a nightmare, not a resolution, IMHO. Full porridge and loud noise even at basic ISO.
          Such matrices do not pull budget optics from Canon, this is a fact.

          How is it that RP has no eye-tracker? And this is what (quote from the site): "Eye AF works on the Canon EOS RP in single-frame AF modes, as well as in still and video modes with AF tracking, which allows you to create clear frames when shooting both static and moving objects"

          For a normal 4k video, frankly speaking, both options are poorly suited, with Canon, normal 4k began only with the EOS R5 and R6.

          And at low ISO, RP of course will also have an advantage in the form of an increased resolution of the final picture, why exactly - see above - the picture will be more detailed and cleaner. Much.

          • Maksim

            What do you expect from budget optics? Uncompromising quality at 200% magnification)))

            • Victor

              What 200?))) There and at 50% unreadable porridge))

              Well, the lens under 40k is not so budgetary, rather average.

              We are talking about the fact that there is practically no adequate modern optics (and after all, the 18-135 nano usm was designed as a modern lens) canon practically does not have for new crop matrices, you can resize, yes, but IMHO this is a useless load on memory cards and a PC))

              And note that none (!) Of the progressive companies currently uses 30 + mp on the crop sensor, they probably understand something))

              • Oleg

                Yes, he framed the kenon with its 30 megapixels. The previous 80d in terms of the photo is even more balanced

              • Arkady Shapoval

                24MP on a Canon EOS EFS / EFM crop, used on many cameras, gives the same pixel density as 61MP on a full frame. Few optics will allow this at an open aperture, especially at the corners and edges of the frame. But resolution is not the only thing that makes 24-35MP good at crop. It's also potential 8k video and dynamic range. And if, nevertheless, there is a good lens and competent processing / raw conversion, then the potential of these 30+ megapixels is higher than that of the previous generation sensors of 18 megapixels.

              • Victor

                Canon has barely mastered high-quality 4k (on the R5 and R6, it will probably be the same on the R3), I think there is no question that at least good 90k will appear on the 4D.

                Optics need good, yes, and Canon simply does not have one for a mirror crop (sigma has, but that is not always friendly with Canon)
                If you press 18-135 (and where to clamp with such a density - the diffraction limit, go, in the f / 5 region, then only deterioration) - most likely it will be better.
                In general, you need a resolution - 18-135, any for 90d is not the best choice, it is not necessary - there is no care, resize to ~ 12 ... 16mp and ok))

                But I would take 80d under the photo (if we take the Canon mirror crop). A purely personal opinion, I do not impose on anyone :)

    • Arkady Shapoval

      I think that a mirror crop, including 90D, is already a road to nowhere.

      • Victor

        Unfortunately (or fortunately), yes.

        The mirrorless can still somehow leave due to the optimal balance of dimensions / price / picture.

        • Seladir

          I almost switched to the Canon M50 II, but the ergonomics ruined everything - both the camera itself and if you screw something a little large on it, especially through an adapter. And with a native 15-45 or native fixes, it is certainly cool and convenient.

          • Victor

            It is needed for native (as an option - non-native, the same cool 16-30-56 sigma) fixes and compact zooms. The adapter is understandably a temporary option, and the convenience of a camera screwed to the lens is often questionable.

            And so from crop-mirrorless cameras, the grip of the m50 is quite convenient (for comparison, hold the canons m100-m200 in your hands, that's where the nightmarish grip is as it is, even with light lenses)

      • Seladir

        I now use 60D - I really like it, but I still want a modern camera in terms of the matrix, AF sensor, video capabilities.
        There is a set of EF-S / EF lenses, so I gravitate towards the same system.
        I understand that this is a road to nowhere and 90D is the swan song of the system. But it will be enough for me for years, I am mostly interested in amateur macro / landscape photography. That is, I will just stay with her, no matter what happens on the market.

        • Arkady Shapoval

          Then it's easier to add something from optics under 60d

        • Aleksey68

          I, among other cameras, have a 60D, there are no problems with it. restrictions - yes, there are. but you need to know them and take it easy. AF, after adjusting all points, in general, working, again, at all points. corrections for lenses are registered in it, so there is no AF accuracy with normal light and straight hands. I often shoot with it on manual optics with ML support, because its display has a higher resolution than that of the second gloom and a more sane color, in any case I managed to calibrate it. to do the same with the display of the second gloom is almost impossible, alas. I use all cameras with battery grips, only original ones, very convenient. for 60D I was looking for an original pen for a very long time, found it with great difficulty (this is not now, but in those years when it was still produced)

  • Oleg

    There are a lot of SLR cameras on hand, and mirror optics will attract with their availability for a very long time, at least on the pages of Radozhiva, the topic of the mirror will not soon disappear. At one time in Vilnius, I came across a new 80d at a price of 600 euros against an RP for 1300 dollars. The price, design and dd of the mirror crop turned out to be better, and it's a pity to take the RP for cycling with its open matrix on dusty roads. Considering that I take an average of 10000-12000 shots per year, this camera will be enough for me until the end of my days. Full frame attracts primarily with the opportunity to try the classic focal lengths 35,50, 85mm with its small depth of field. Well, yes, the time of the mirror has passed. There are rumors about the development of a full frame by kenon at a price of $ 800 and if this happens then the concept of crop may disappear soon

  • Aleksandr Bozhkevich

    Native RF 1.8 now costs from 550 dollars to 750. This one can be found for a little more than 300. And at home, not everything is so buzzing. For example, the same chromatic is also present there ...
