In this review, I will call the YONGNUO YN42.5mm F1.7M II lens for short. Yongnuo 42.5 / 1.7 II.

Important: Radozhiv already has a review of the first version of this lens - YONGNUO 42.5mm 1: 1.7... Due to the fact that the lenses are very similar, in many ways this review will repeat the review. YONGNUO 42.5mm 1: 1.7.

In short

Yongnuo 42.5 / 1.7 II is a short telephoto lens for the Micro 4/3 system. Primarily aimed at portrait and creative photography. It is suitable for Panasonic and Olympus Micro 4/3 system cameras, as well as other brands that create their photo and video cameras based on the Micro 4/3 (Kodak, Xiaoyi etc.)

In general, the lens is not bad. Of the obvious advantages: confident operation at F / 1.7, a stepping motor for focusing, lightness and compactness, as well as a very low cost of the lens.

Of the obvious shortcomings, I can only highlight the incompatibility with some cameras.

Important: reliably knownthat Yongnuo 42.5 / 1.7 II will work correctly with Panasonic G100, GH5, G9, G95, G85, GX9, GX85, GF10, GF9, GF8, Olympus E-M5 Mark II, E-M10 mark III, E-M10 IV cameras , E-PL9, E-PL10, PEN-F. How he will behave with other models is unknown. For example, on an old camera Panasonic GF2 it works perfectly, but on Panasonic G2 not recognized at all.

YONGNUO YN42.5mm F1.7M II (42.5 F1.7 STM)


October 14 2019 year was officially announced YONGNUO 42.5mm 1: 1.7... It was the first lens from Yongnuo for the Micro 4/3 system.

At the end of summer 2020, the Yongnuo 42.5 / 1.7 II lens was officially presented (version from this review). It is an improved, modified version of the previous YONGNUO 42.5mm 1: 1.7.

The Yongnuo 42.5 / 1.7 II is the second lens for the Micro 4/3 system from Yongnuo. Recently, all Yongnuo lenses only carry the 'YnLens' lettering on their bodies, but the Yongnuo 42.5 / 1.7 II still uses the classic 'Yongnuo' spelling.

Differences between versions I and II

The main differences that I could find between Yongnuo 42.5 / 1.7 and Yongnuo 42.5 / 1.7 II:

  1. The first version is older, released in autumn 2019. The second version is released a year later and is newer.
  2. Versions have different case design.
  3. II version has small focus mode switch, placed on a special platform, which is fixed with two screws. The first version had a huge focus mode switch without this pad. Many users did not like the design of the first version precisely because of this huge focus mode switch. Although I must admit that the huge switch was handy enough.
  4. II version has another frame near the front lens, which looks more harmonious than the first version.
  5. Different versions have text and additional marks are applied in different places and in different colors... The second version has additional designations 'STM', 'II' and 'M' (F1.7M).
  6. II version better optimized to work with modern cameras.
  7. II version has no lateral backlash focus rings.
  8. II version has tighter focus ringbut still handy enough for comfortable manual focusing.
  9. II version focuses much quieter.
  10. The II version is a little more expensive, but most likely the price for the II version will stabilize and will not differ much from the price for the previous version.

Lenses use the same optical design and generally very similar to each other.

Y0ngnuo classifies the Yongnuo 42.5/1.7 II as a standard (in terms of focal length) lens. In terms of full frame EGF the lens is 85 mm, and the equivalent aperture in terms of depth of field is F / 3.4, as a result, in terms of viewing angle and depth of field, this is a class 85 / 3.4 lens.

On select Olympus models, an in-camera stabilization system will work, making the Yongnuo 42.5 / 1.7 II even easier to use.

YONGNUO YN42.5mm F1.7M II (42.5 F1.7 STM)


The lens came to the review completely new.

In a small box was a warranty card, instructions in Chinese and English, a certificate of quality control, a desiccant and the lens itself with a front and rear cover. The covers are made of thick plastic. In the box, the lens is mounted with two cardboard holders.

Yongnuo 42.5 / 1.7 II has metal mount... The focusing ring is very wide, plastic.

The Yongnuo 42.5 / 1.7 II lens weighs just 135 grams. It weighs almost the same and Panasonic 42.5 / 1.7.

Diaphragm consists of 7 blades; on heavily covered diaphragms, the aperture has the shape of an irregular heptagon. During the closing / opening of the blades, the diaphragm makes a little noise and has a slight lag. Noise and lag are small and do not interfere with comfortable work.

The hood is not a bayonet type and must be screwed into the thread of the front filter. The instructions do not indicate the marking of the original hood. It is not known which hood will fit this lens. The Yongnuo 42.5 / 1.7 II works well in backlighting, and therefore the use of a hood is optional.

The design of the case is laconic, simple, and pleasant to look at.

YONGNUO YN42.5mm F1.7M II (42.5 F1.7 STM)


For focusing, the Yongnuo 42.5 / 1.7 II uses Yongnuo STM focusing stepper motor (in the 'SMT' manual). Auto focus should work with all Micro 4/3 cameras.

Focus speed average (closer to high), quite comfortable for work. On camera PANASONIC LUMIX DMC-GF2 I didn't have much focusing problems.

Auto focus is enough quiet, but still there is a slight noise, characteristic of stepper motors, reminiscent of the hum of a transformer. The noise from the motor is much lower than that of the previous version of this lens. The noise level during photo and video shooting is the same.

Lens uses electronic focus ring. The focus ring is plastic, wide, in manual focus mode it rotates approximately three full turns. When extreme positions are reached, the ring does not abut, but continues to rotate. Manual focus very comfortably... The focus ring rotates with little effort. I did not observe a delay when changing the direction of rotation. The focus ring makes a faint sound of two plastic parts rubbing during manual focusing.

There is a 'AF-MF' (auto focus / manual focus) mode switch on the lens body. During auto focus focus ring remains stationaryMoreover, it can be freely rotated 360 degrees without any effect on focus (if the corresponding function is enabled in the camera menu). Lens supports continuous manual focus controlbut only if allowed by the camera settings.

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 minimum focusing distance is 30 cm, while the maximum magnification for macro photography of 1: 6.67 can be obtained.

The Yongnuo 42.5 / 1.7 II has a 'Focus Breathing' effect (changing the angle of view while focusing). When focusing towards the MDF, the angle of view decreases.

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

Important: this is a third party lens. It may happen that it will not work on some cameras. For example, Yongnuo 42.5 / 1.7 II is not recognized by the camera PANASONIC LUMIX DMC-G2on camera PANASONIC LUMIX DMC-GF2 AF / MF switch does not work (lens always uses auto focus, even in 'MF' mode).

Image quality

Yongnuo 42.5 / 1.7 II easily handles 12MP CMOS sensors PANASONIC LUMIX DMC-G2 и PANASONIC LUMIX DMC-GF2. Optically, this is a good middling without obvious serious flaws.


  • good sharpness at the open aperture in the center of the frame
  • in the corners of the frame, sharpness becomes acceptable after f / 2.8-4
  • good resolution in the center of the frame on covered apertures in the area of ​​F / 2.8


  • weak distortion
  • 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 / 1.7 and focusing on infinity
  • vignetting decreases with focus towards MDF
  • vignetting almost disappears at f / 2.8-4
  • vignetting is easily fixable in the editor


  • chromatic aberration fixed well enough
  • general level HA is on a par with similar quality lenses
  • there is friging (color of contrast zones of blur in green and purple)
  • Blur discs have pronounced color fringing


  • the effect of the rays of the star is not pronounced (14 rays)
  • Blur disks are uneven on tightly covered diaphragms
  • the lens works well in backlighting, only in the most difficult conditions can you get a slight 'rainbow' or flare
  • at the edges and corners of the frame, the discs of confusion at F / 1.7 turn into lemons, the bokeh is slightly twisted
  • the lens does not use aspherical elements, only ED elements, which helps to avoid concentric 'onion' circles on the discs of confusion

There is still no profile for this lens for popular RAW converters.

My experience

The Yongnuo 42.5 / 1.7 II had some bug fixes for the first version of the lens. The result is a fairly high-quality and balanced lens.

I can safely recommend the Yongnuo 42.5 / 1.7 II to anyone who wants to try a 'real' Micro 4/3 portrait lens.

First of all, Yongnuo 42.5 / 1.7 is a competitor to cheap XIAOYI XIAOMI 42.5 / 1.8Which You can find 80 dollars each.

To create this review, I specifically acquired a classic 'beautiful' camera Panasonic G2 and it's a pity that Yongnuo 42.5 / 1.7 II didn't want to work with it. But this is rather my personal mistake, since I have not read the list of supported cameras on the official website. Previous lens version I worked wonderfully on Panasonic G5.

Video review


The Yongnuo 42.5 / 1.7 II is a decent creative lens. A find for the amateur photographer. Better in detail than the previous version YONGNUO 42.5mm 1: 1.7.

    thanks for the review!
    It's a pity that m4 \ 3 is a dead system (IMHO)

      Dead / not dead, why be sorry?

      Until Panas refuses, she cannot be called "dead".

        You say it is as if cameras have ceased to be made under the Olympus brand.

    It's a pity they didn't make an analogue 77, it would be interesting

  • Bukozik

    The office that will buy Olympus is already making plans to release new cameras ... So no funeral service is needed)

    • R'RёS,R ° F "RёR№

      Mikra has been buried since 2009, when she was introduced, and people who have never had cameras on this system.

      • Arkady Shapoval

        In the announcement of the new OLYMPUS M.ZUIKO DIGITAL ED 150-400mm 1: 4.5 TC 1.25X IS PRO there are whole battles on this topic. Meanwhile, Olympus apologizes that does not have time to deliver this lens to everyone.

        • Sergei

          Arkady, do you want a joke? Almost 7 years ago on your site I wrote a commentary on the review of the Olympus OM-D E-M1 with whale 12-50, and I wrote that this is all doubtful and the matrix is ​​frankly weak! But literally a year later, I sold cropped Nikons and took an E-M5 mark II with the same lens and with a similar matrix, and later, exactly like that, I settled on a microscope and overgrown with glasses. Accidentally went to read an ancient topic, it turned out funny. : D

      • Victor

        Quite a lot and a lot are “buried”, but given the permanently low market share of Olympus, it’s surprising how he lasted 10 years in this segment.

        • York

          Market share alone is not an indicator.
          Margin, form of ownership, relationship between shareholders / owners and management, company structure ... Lots of things.

          Fujas with Panas hold something around 5%, and do not hum very much.
          Nikon was a leader, he became unclear with what, and he is also quite holding on.
          Sigma, as it was alternatively gifted in the head, remained - a family office, what to take from them.
          Pentax is generally more like a sect, its market is zero point fucking tenths of a percent ...

          It is unlikely that the olik was bloody on its own, there are also shareholders who always have little money, and the long and fascinating history of na- and proipalov - apparently, the managers decided to yield to the pressure of the owners.

          As an owner of the oligarch, the absence of a new shmurdyak does not bother me much, but hypothetical problems with the service make me nervous.

        • Sergei

          It's just that Olympus, like Nikon and Canon, receives his main income not from the photo department, but from medical equipment, as far as I remember. But JIP may be directly dependent on the income of the unit entrusted to it. And besides the outcome expected by many, this can turn into a “second wind” of the system and a wave of innovations.

          Even if we assume the worst case scenario, current users will not be very stressed. The service will be available, but the loose will be available for a long time. If you look at the same Minolta, there was no end of the world for its users.

          • Michael

            How to say. Both Minolta and Pentax are very problematic systems. You can sit on them only if you have everything. Third-party vendors are quick to abandon development for such systems

            • Sergei

              Any system is problematic to one degree or another.
              Well, I have everything, almost now and for a few more years all the glasses will be available new, and on the secondary housing for another ten and a half years. I bought myself a telephoto camera from a 4/3 mirror system, although when I started photographing on Nikons back in 2013, I did not even know that there was such a system. And I bought glass this summer, used naturally. But as it turned out that glass under the mirror Oliki ceased to be produced just the other day.
              It is clear that it makes no sense for new photographers to buy Minolta today, for example, Sonya, that is, half-mirror. But those who filmed her at the time of her death had no problems with support.
              And micra is, one might say, a complete system where everything you need is already there. What will be produced there next? Hole zooms 1.8-2? Well, only a few will buy them, obviously not those who are in a hurry to celebrate the office. Otherwise, everything is OK so far, wait and see.

              • Michael

                Availability (you can get it) and the price of the same Pentax is such that it takes a shiver. It is clear that you can get a devil with horns, but there is a question of money and time. I don't want to be a collector) And while Olympus is still full in stores and on the secondary, there are no problems

            • Sergei

              Personally, I like Pentax in absentia, there is little there, but pretty good. If the price does not suit - well, do not buy, as there are other options. There are no rules by which the price of certain cameras should be determined. The price of Panasonic S is also high, well, nothing can be done about it. Until a certain moment I thought that the mikra was an expensive system, until I decided to calculate how much a similar set on Nikon Z5 / 6 would cost me. : D Yes, these are slightly different things, a lot of nuances, but still.

              • Michael

                I had it) And when “I don’t want a whale” starts, you turn into a collector. Looked at it all and gave it away.

            • Sergei

              Ah, got it. I've been looking for a super-broad on the micra and something is somehow expensive and it seems like this money is not worth it. But I looked at FF and the situation there, in general, is not better. Just for $ 1100, which costs a panaleyka 8-18, you can take a used FF with super-wide, although it will also not be very convenient to keep a separate system for only two subjects - landscape and astro-landscape. And on the main system, the landscape will be limited to 24mm EGF. And you won't be able to shoot lightning at a wide angle either ... In general, this is such a painful choice. : D Everywhere has its limitations. If only Sigma could fit into ultra-wide zooms under a micro ...

      • Pokemon

        I recommend to all well-wishers who sincerely tear their vest on themselves about the longevity of a double-crop, gather their strength, take eggs into a fist, and go and buy the following soup set:
        Olympus OM-D E-M1X
        Panasonic Lumix GH5
        Olympus OM-D E-M1 Mark III
        some of this, yeah, and glass to the heap:
        Olympus ED 12-40mm f / 2.8 Pro
        Panasonic 12-35mm f / 2.8 II ASPH. OIS Lumix GX Vario
        It's very hard to worry about your favorite brand just sitting on the couch.
        We need to support her $$$.

        • Victor

          12-40 pop.

          It is imperative that a supertele from that topic and some 10-25 / 1.7 drink to the heap.
          This will be a serious approach.

          • Arkady Shapoval

            Elmarit 200 / 2.8 or Zuiko 300/4 for micra is much more expensive :)

        • Yevgeniy

          As soon as the money appears, I will definitely buy 10-25 / 1.7 and 40-150 / 2.8. And more cameras ... most likely E-M1 Mark II and G9 or GH5.
          Although, I have enough GF1 and G5, to be honest. I do not shoot any sports (although there was such a thing, and it worked quite well), and there is no cinema either in the future.

        • Sergei

          You have a strange set of components duplicating each other.
          Well, I just went and bought an e-m1 mark III not so long ago, soon I'll go buy the missing glasses. : D
          And judging from the context, it is not clear why buy Hashik and 12-35? You need to buy what you need, and not to “give money” to someone there ...

          • Pokemon

            So I wrote about something.
            God help, invest further.

    • B. R. P.

      Ricoh Pentax already bought once, yeah.

  • Paul

    Judging by the review, with the first version, there is no point in buying this lens: optically they are the same, and with a little addition, you can buy a used Olympus 45 / 1.8, which will be even better optically. In the first version, at short focusing distances, I noticed a slight shift to the front focus (which is noteworthy, the Yi 45 / 1.8 has a slight shift to the back focus), naturally, as the distance to the subject of photography increases, the depth of field increases and there is no big problem in this, and more the first version has some "oddities" in the focusing system when installed on Olympus OM-D devices of the younger line (10, 10ll in electronic shutter mode): return to a certain point after each shot. I wonder how this is the case with this lens. About the hood: in terms of thread and size, the hood from Jupiter-37a is perfect for this lens, it is deep enough and does not create vignetting.

    • Arkady Shapoval

      Thanks. Here are just the original hood from the Yu-37, metal and heavy

      • Paul

        Included with Jupiter-37a were 2 types of blends (perhaps there were some other options, I have 3 of the same out of 2): a plastic “one-sided” (attached only in the working position) and a metal “two-sided” (screwed not only in working, but also in the "transport" position). And the weight of the metal hood is not very large.

        • Arkady Shapoval

          Thank you, I didn’t know that there were plastic hoods under the Ju-37

          • Paul

            Here are both options:

          • Oleg

            Mine is 84 with plastic one-sided. They suspect that the “younger” ones are all with this.

    • Yevgeniy

      There are enough blends with such a thread for aliexpress. Metallic. Lungs. I took it, but I'm not using it. Stopped at the transition ring 52-30.

    • Neo

      Native Panas has never seen cheaper than $ 200-250, the same 70 bucks were on Black Friday, 3-4 times cheaper

  • Yevgeniy

    Thanks. The switch looks human, but not as convenient as it seems to me :)
    I am glad that the huge Yongnuo inscription around the front lens was not painted over with white, but it flares very reliably, although it is unlikely to be as noticeable as in the first version (I put the adapter ring 52-30 and calmed down, it looks very extravagant). As for the rest, it seems to me that nothing has changed. Engine noise doesn't bother me at all, although it's clear what could be done better. The picture on the open one in the center was very sharp and remained. In general, anyone who has not bought can choose anyone who looks more like it, I think. And the owners of the first version don't need to worry at all.

  • Sergei

    Personally, I would refrain from buying such glasses. Well, unless you bought a secondary camera there for $ 40, but you didn't find the same lens for some reason. For those who can afford modern carcasses, I think it is better to take a native cheap portrait, well, or by paying a little extra Sigma 56mm f1.4, on a secondary or new one.

    • Oleg

      Native with about the same focal times 3-3.5 more expensive. Used sigma too. Not everyone is amused that they "can afford", many just love to take pictures)).

      • Sergei

        Well, I talked a lot with Chinese products and in general I can only recommend avoiding them almost always, if possible. It is also known that the miser pays twice.
        You can love taking pictures with any technique. Simply, the quality of the photographing process may depend on the quality of technology. Maybe the lens will dull or will not work for long. And maybe everything will be OK, but personally I do not want to risk it.

        • Arkady Shapoval

          I used all the lenses from Yongnuo (except the new 35/2 under bzk), with some of them I got 50.000 frames. I can say with confidence that each model is special, there are very successful ones, there are very unsuccessful ones. The breakage happened only once with the model 50 / 1.4 for Nikon, which I sold, it broke already from the new owner and was repaired for about $ 20. I ran about 5000 frames. Some lenses gave me a lot of positives (100/2 under Nikon, 35 / 1.4 under Kenon), from some lenses (85 / 1.8 under Nikon). Under the bzk there are 42.5, 45.2 ii, 50 / 1.8, 85 / 1.8 are very successful, 85 / 1.8 will be reviewed soon, just the holy grail for $ 200. For advanced hobbyists, these are very interesting solutions. The negative for Yongnuo mainly comes from the breaking 50 1.8 under Nikon and Kenon. These were their first lenses, which were mechanically not very successful. Their new solutions are head and shoulders above. For example, 50.000 shots is roughly two years of shooting for an amateur photographer. There are a lot of subtleties here, and it's not so easy to say something about modern Chinese solutions.

          • Sergei

            Yongnuo personally did not hold it in his hands, but even from the photographs one can see the cheapness and some luridness of their manufacture. I also do not presume to assert something for sure, but personally I would not contact without an urgent need. On the positive side, it can be noted that they practically do not use special elements in optical circuits, which means that there will be no “onion rings” in the circles of confusion, which seem to be associated with the presence of aspherical lenses in optics.

            So I have two Sigmas on the mic - 30mm and 16mm f1.4, so I'm thinking of buying another 56mm. On Nikon it was 10-20 sigma, I don't remember any special problems. But all ee third-party glass for Canicons with closed specifications and for an open micra is a little different. Although Yangnuo managed to achieve incompatibility and jambs on an open mount, judging by the comments.

            It is clear that now almost everything is done in China, but there are two big differences between what the Chinese do themselves and what they do under the strict control of global brands.

            • Arkady Shapoval

              Well, here are 2 units of glass, not all originals have something like that. You don't need to go far - analogues 85 1.8g Nikon, 85 1.8 Usm Canon without special elements. Panasonic 42.5 / 1.7 has one aspheric in total. Everything is very relative. I, too, was once skeptical of the yongs, especially the 42.5 of the first version, in a review in personal experience I also wrote that at first it seems like a toy. But this is exactly up to the moment of viewing photos on a computer.

        • Yevgeniy

          I can say that the Chinese Godox is vastly superior to the American PocketWizard in its main function: remotely igniting flashes. I would stay away from the American PocketWizard. And even a flash from Canon once bathed in an American store turned out to be buggy (regardless of the settings, it always hammered to maximum). So just say that Chinese is worse only because of its Chineseness ... well, you must have been in hibernation for twenty years. I have no other explanation.

          • Sergei

            Perhaps there are always some particulars. I have a Yongnuo flash and a smart synchronizer for Nikon, which can remotely twist the puff settings. I have zero questions for this set, although maybe because I have used it twice in the last five years, since Olympus bought it. Even with the flash of this retractable reflector, it is difficult to pull out, you have to use a coin, either the marriage or the quality is like that.
            I also have a Chinese tripod with an Alik and nothing like that for 50 bucks, without enthusiasm of course. I also rarely use it, only for astro, in other cases the stub saves. If I were buying a tripod now, I would not buy one.

  • Alexander

    Hello everybody. Who has not tried it on the OM-D E-M10 Mark II? Is autofocus working or not?

    • Arkady Shapoval

      Most likely no one will tell you. I suppose it should work.

      • Alexander

        Thank you. It's a pity it's over. It's just that a person has experience with the first version. Did not work.

  • Arkady Shapoval

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

  • Eugene

    It also works with G5 and GF1, although this is the first version.

  • Alexy

    Arkady, in this fragment “on the old Panasonic GF2 it works perfectly, but on the Panasonic G2 it is not recognized” both links are the same on the G2.

    • Alexy

      Someone tried the thread on the E-M1, does it work?

    • Arkady Shapoval
