On Radozhiv already have my review YONGNUO LENS 100mm 1: 2 (YN100mm F2) for Canon EOS cameras, but due to some significant differences, I decided to make a separate review on the Yongnuo 100/2 version for Nikon cameras.

In short

Yongnuo 100/2 - copy of the original full-frame lens Canon Lens EF 100mm 1: 2 Ultrasonicreleased by Yongnuo Digital for Nikon cameras.

The Yongnuo 100/2, as indicated on the box and corresponding to reality, acts as a fast aperture telephoto lens with a fixed focal length.

Yongnuo 100/2 attracts with its low cost and features similar to the original Canon Lens EF 100mm 1: 2 Ultrasonic. Nikon does not have a complete analogue for the Yongnuo 100/2, but an old man who looks like him Nikon AF DC-Nikkor 105mm 1: 2 D Defocus Image Control still very different from Yongnuo 100/2. The closest in functionality to the Yongnuo 100/2 is the original Nikon AF-S Nikkor 85mm 1: 1.8G IF SWMI will often compare Yongnuo 100/2 with in this review.

Generally Yongnuo 100/2 relatively good and is a very attractive lens for amateur photographers as an inexpensive creative lens, primarily intended for portraiture.

Spoiler: Yongnuo 100/2 for Nikon cameras turned out much better than its predecessor YONGNUO LENS 100mm 1: 2 (YN100mm F2) for Canon cameras. It does not have serious problems with focusing and is optically noticeably better. Maybe in a review YONGNUO LENS 100mm 1: 2 (YN100mm F2) for Canon cameras I have not been the best copy. Also, the version for Nikon received a USB port for updating the firmware, it became heavier, with a longer stroke of the focus ring and a slightly modified body design (no corrugation at the bottom of the lens) and a couple more minor changes appeared.

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon


Yongnuo 100/2 for Canon EOS cameras first appeared on the official website on October 31, 2016. One year later, August 1 2017 the Yongnuo 100mm 1: 2 lens (YN100mm F2N model, as in this review) for Nikon cameras appeared on the site and at the end of September 2017 was already on sale. In fact, the version for Nikon cameras is much newer than the version for Canon.

The Yongnuo 100/2 is the first lens of the company, which has almost the same body design for the versions for Nikon and Canon (in fact, there are several serious differences).

Let me remind you that the first lens from Yongnuo Digital was a fifty dollars for Canon EOS cameras - Yongnuo Lens EF 50mm 1: 1.8 (YN50mm F1.8) submitted on December 27, 2014. And the first Yongnuo Digital lens for Nikon cameras was YONGNUO 50mm 1: 1.8 (YN50mm F1.8N, prototype shown July 10, 2015).

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon


The lens came to the review completely new.

In a small box is a warranty card, instructions in Chinese and English, a desiccant 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. The front and rear lenses of the lens are initially covered by special transport films.

In general, the lens is assembled well. Yongnuo 100/2 has metal mount mount. The focus ring is rubberized. Front of the lens housing (from the focus ring to the front lens) made of metal. Metal thread for the filter (suddenly!). The back of the lens (from the focus ring to the bayonet mount) is made of plastic. It is stated that the contacts of the microcircuits are gold plated to improve the passage of current. The weight of the Yongnuo 100/2 is approximately 450 grams (the same Nikon 85 / 1.8G weighs 100 grams less).

Of the serious flaws in the assembly, I want to highlight the tangible backlash of the focus ring, as well as metal knock associated with this backlash (when you touch the ring, you can hear metal gently hitting metal, tapping). If not for this backlash, then by touch distinguish Yongnuo 100/2 from Canon EF 100 / 2 USM it would be very difficult.

Diaphragm consists of 9 petals and form a hole in the shape of an irregular hexagon, while in the photos in the blur zone rather round discs of blur appear in the range F / 2-F / 8.

The lens has a USB port in the lower rear of the lens (in the bayonet area).

Unfortunately, the bundle does not include a hood, a bag for transportation, a USB cable and a software disk (software can only be downloaded from the official website).

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon


The lens has built-in focus motor DC-type (DDirectly Current Motor- ordinary DC motor). To be precise, the Yongnuo 100/2 is an analog of the Nikon series lenses AF-I. Unlike lenses Nikon AF-Sthat use ultrasonic focusing motors Nikon SWMold lenses Nikon AF-I use a built-in buzzing micro focus motor similar to the Yongnuo DC.

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

When focusing, the motor is noisy. The noise is small. Yongnuo 100/2 makes less noise than motorless Nikon AF DC-Nikkor 105mm 1: 2 D Defocus Image Control. At the same time, the Yongnuo 100/2 is not much more noisy than compact ultrasonic motor у Nikon 85 / 1.8G.

Auto Focus Speed average. Focusing speed is enough for comfortable work in most photo tasks. Autofocus speed similar to lens Nikon 85 / 1.8G.

When used on cameras Nikon D90, D5000, D5100 (with unpretentious Multi-CAM 1000 focusing system), Nikon D40 (with the simplest Multi-CAM 530 focusing system) and with Nikon D700 (with advanced Multi-CAM 3500FX Focusing System) I did not have any particular problems. The quality of work varies slightly from camera to camera. But I must note that the tenacity of focus is low and much worse than that of the original lenses.

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.

The focus ring is rubberized and in manual focus mode rotates approximately 120 degrees. When extreme positions are reached, the ring does not abut, but continues to rotate. The focus distance scale rotates in the opposite direction of the focus ring rotation. Manual focus is quite convenient. Focus ring can easy to rotate with one finger. During manual focusing, one can hear 'plastic rubbing against plastic or metal', while the ring rotates smoothly and is quite pleasant.

There is an 'AF-MF' (auto focus / manual focus) focus mode switch on the lens barrel. Switch positions are reversed compared to original lenses ('AF-MF' <-> 'M-M / A'). During auto focus focus ring remains stationarywhile it can be freely rotated 360 degrees without any effect on focusing. Unfortunately, unlike many original Nikon lenses, the Yongnuo 100/2 does not support continuous manual focus control Nikon M / A (or similar).

Lens has internal focus, the front and rear lenses remain stationary during focusing. It is possible to use various filters without any problems. I easily used a Yongnuo 100 / 2 with a polarizing filter HOYA 58mm PL-CIR.

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

The minimum focusing distance is 90 cm and the maximum magnification ratio is 1: 7.2 (0.14 X magnification, slightly better than Nikon AF-S Nikkor 85mm 1: 1.8G IF SWM).

Focus Features:

  1. Important: the quality of the focus of the Yongnuo 100/2 in Live View is highly dependent on the firmware and the camera used. It is authentically known that Yongnuo 100/2 with firmware 1.05 does not have special focus problems in Live View with Nikon D90, but still focuses very slowly (more of a problem is the focus method in contrast). And here, as an example, on the camera Nikon D600 и Nikon D700 the Yongnuo 100/2 lens with firmware 1.01 has obvious problems in Live View.
  2. Yongnuo 100 / 2 has a very pronounced 'Focus Breathing' effect (changing the viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases (usually with internal focusing lenses, the angle increases).
  3. Focus Shift (focus shift, changing focus distance due to iris)
  4. Yongnuo 100 / 2 does not have a hard stop (hard infinity mechanical stop) which allows you to accurately and quickly focus the lens to infinity under any external temperature conditions. For accurate aiming at infinity, you cannot just bring the focus ring to its extreme position.
  5. The lens transmits the distance to the subject in the camera and is Nikon D-lens equivalent... How exactly this function works is unknown, but I noticed the following distances: 6, 2.1, 0.94, 1.2 meters. Most likely, there shouldn't be any special problems with the flash, but it was not possible to check the lens in detail. Nikon flash for simple situations SB-910 in i-TTL modes with this lens worked correctly.
  6. With the lid closed, the automatic focusing of the lens does not run the lens over the full focusing distance, as the vast majority of Nikon Nikkor lenses do. With the lid closed, the lens runs from two meters to infinity and back, or from MDF to 1.2 meters and back. If you remove the cover, the lens focuses using the entire available range of focusing distances. Inexplicable but the fact.
  7. Important: Yongnuo 100 / 2 is a third-party lens. It may happen that it will not work correctly with some cameras. Details on this issue are considered by me. here... It is not known whether the possibility of updating the firmware will help. As an example - on camera Nikon D40 the lens sometimes freezes / falls asleep for 2-3 seconds, after which it begins to focus again without obvious problems.
  8. Some users report problems with focusing during use. external flash with some cameras. No exact data.
  9. Unknown compatibility with teleconverters.
  10. Unknown compatibility with FT-1 adapter for system cameras Nikon 1.

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon

Exposure Issues

Important: some cameras have a problem with automatic metering exposure. On camera Nikon D90 with any metering settings exposure the built-in exposure meter lies about -2 steps (i.e., you need to make a correction exposure +2 EV). I already saw a similar problem with the lens Yongnuo 40 / 2.8.

Perhaps, on some cameras, this problem is only available during focusing using a single focus point. No exact data.

Important: Yongnuo 100/2 firmware update eliminated metering problems exposure in the chamber Nikon D90... This error is indicated in the firmware as “Fix automatic exposure anomalies”.

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon

Firmware Upgrade

There is a USB port on the lens housing of the Yongnuo 100/2 with which you can update the lens software (firmware / firmware). This function first appeared just at Yongnuo 100mm 1: 2 and Yongnuo 40 / 2.8that were presented at the same time. Unlike Yongnuo 40 / 2.8The Yongnuo 100/2 USB port is in an inconspicuous place.

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 be found on the official website. I found firmware for my Yongnuo 100/2 here.

A widespread USB 2.0 MICRO-B port is used to connect to the lens (most mobile phones use just that). A USB cable is not included. To connect, I used the USB cable for my Android phone and without any problems updated the firmware from V1.03 (2017.12.20) to V1.05 (2018.01.17). The procedure took less than 10 seconds.

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

To upgrade the firmware (software) of the lens:

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

Image quality

With the image quality, the Yongnuo 100/2 is not bad, or even normal / good.


  • in the center of the frame on F / 2.0 the resolution does not shine, but still it is enough for many photo tasks
  • there is a noticeable drop in sharpness to the edges of the frame at f / 2.0
  • at the edges of the frame, sharpness becomes acceptable after f / 4.0
  • good / excellent resolution in the center of the frame on covered apertures after F / 2.8


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



  • open diaphragms have a noticeable amount of spherical and chromatic aberrations
  • the strongest chromatic aberration visible at the edges and corners of the image
  • general level HA is at the level typical for such lenses
  • there is strong friging (HA in the blur zone) and blooming (HA on very contrasting small details)


  • it's important: On covered apertures in the center of the frame, a whitish veil may appear in slightly contrasting subjects. This property has many old lenses, especially macro-weaving.
  • color rendering is neutral, pleasant. The lens uses front lens enlightenment, which casts green shades. Many modern lenses have enlightenment that shimmers like the Yongnuo 100/2.
  • in some situations, the lens is very afraid of side and back light. May be tangible drop in contrast in side light. Most likely, this behavior is due to the fact that the front lens is located immediately behind the filter, and the use of the lens welcomes the installation of a lens hood.
  • in many scenes, the lens can create a pleasant / neutral / cream bokeh

Video review

A brief video review can be viewed on my Youtube channeleither here:

My experience

In my opinion, the YONGNUO 100/2 is the best cheap 'true' portrait lens. 'Real' in terms of focal length, aperture ratio and picture. Such a powerful Holy Grail for the amateur photographer. The professional will pass by YONGNUO 100/2, but the amateur photographer can get a lot of positive from the picture from 100/2.

Somehow it turns out at Yongnuo that the lens versions for Nikon and Canon are significantly different. Typically, versions for Nikon are more functional with better builds.

On Nikon DX cameras EGF lens YONGNUO LENS 100mm 1:2 YN100mm F2N will fit 150mm due to crop factor. On the crop, this is something in between 135/2 and 180/2.8, such EGF convenient enough for portrait shooting in open locations.

Personally, I liked the Yongnuo 100/2, minor flaws in it practically do not bother me. It is not easy to get a high-aperture `` weaving '' with F / 2.8 (like Nikon Lens Series E 100mm 1: 2.8) or F / 2.5 (like Nikon 105mm 1: 2.5 Nikkor), and with F / 2.0, and even for $ 170 and completely new, it's very cool. As a result, I shot about 100 frames on Yongnuo 2/10.000.

New Yongnuo 100 / 2 costs less than the cheapest portrait original lens Nikon 85mm 1: 1.8 AF Nikkor in a condition B. at.

  1. Information on choosing a portrait lens can be found in the 'Portrait Fixed Lenses for Nikon Cameras'
  2. A list of cheap portrait lenses for Nikon can be found under 'Budget portraits under Nikon DSLRs'
  3. How to achieve maximum background blur with Yongnuo 100/2 is described in the 'Blurred background'

I repeat once again - an autofocus 'weave' with F / 2.0 is much more convenient to use than the vast majority of manual similar lenses, and the number of successful shots from it is several times higher than any manual lens of this type, including common premium class lenses 85/1.4 or 135/2.8.

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon

YONGNUO LENS 100mm 1: 2 YN100mm F2N for Nikon


Nikon has no full counterpart to the Yongnuo 100/2 (at least at the time of this writing). Original Nikon AF DC-Nikkor 105mm 1: 2 D Defocus Image Control is a completely different lens and I don’t even want to compare them (in the case of Yongnuo 100/2 for Canon EOS in the review there was a comparison with the original similar Canon Lens EF 100mm 1: 2 Ultrasonic).

Yongnuo 100/2 for Nikon cameras turned out significantly better than for Canon EOS cameras. Perhaps the option for Canon in the review turned out to be not the most revealing in terms of capabilities, but perhaps it is elementary that the version Yongnuo 100/2 for Nikon new year and it removed some of the flaws inherent in the previous version.

Yongnuo 100/2 is generally a very interesting alternative to the original Nikon AF-S Nikkor 85mm 1: 1.8G IF SWM, especially for Nikon non-motorized camera users. In fact, with Yongnuo 100/2 you can get 80-90% of the functionality from Canon Lens EF 100mm 1: 2 Ultrasonic / Nikon AF-S Nikkor 85mm 1: 1.8G IF SWM.

Despite the primary problems with exposure, the strong focus ring play and rumors of instability of quality from lens to lens, the Yongnuo 100/2 for Nikon cameras is a very attractive lens.


  1. low cost (170 dollars for the new Yongnuo 100/2 against 480 dollars for Nikon 85 / 1.8G or 1200 dollars for DC-Nikkor 105 / 2D)
  2. internal focusing (front and rear lenses always remain stationary)
  3. built-in focus motor (important for owners Nikon DX cameras without focus motor)
  4. quite convenient manual focus
  5. presence of a window with a scale of focusing distances and the depth of field scale
  6. good build quality: metal bayonet mount, metal front of the lens housing with metal thread for filters, rubberized focus ring, hood (theoretically) bayonet type
  7. compact size (length and thickness of Yongnuo 100/2 comparable to a whale lens Nikon 18-55 / 3.5-5.6G VR)
  8. nine-petal diaphragmsufficiently round discs of blur in the range of F / 2-F / 8
  9. no focus shift
  10. fixed focus ring during auto focus (e.g. Nikon 85 / 1.8D the ring rotates and cannot be touched)
  11. Confident sharpness starting at f / 2.2 in the center of the frame. A moderate level of basic optical distortion (aberration, vignetting, distortion), comparable to the original Canon Lens EF 100mm 1: 2 Ultrasonic
  12. nice / neutral drawing, which can be used as a good artistic technique during portraiture
  13. relatively small diameter of filters (58 mm versus 67 mm for Nikon 85 / 1.8G or 72 mm DC-Nikkor 105 / 2D)
  14. There is no full or partial analogue among the original Nikon Nikkor lenses. Good combination of focal length and aperture
  15. USB port for updating the lens firmware


  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. backlash of the focus ring and the knock of the focus ring when it is touched (it seems that the ring is loose)
  3. average focusing speed (but still comfortable for most tasks)
  4. uncertain focus (weak 'focus tenacity')
  5. lack of the function of constant manual focus control similar to, for example, M / A mode у Nikon 85 / 1.8G
  6. possible problems while working with the flash in some TTL modes due to the specifics of transmitting the focusing distance to the camera (a large sample of data is needed for verification)
  7. focus ring and distance scale have different directions of rotation (psychological discomfort)
  8. slight noise from the focus motor
  9. metering problems exposure on some cameras (e.g. Nikon D90 amendment required exposure + 2 EV or lens flashing)
  10. focus problems in live view on some cameras
  11. no hood included, unknown hood type, unknown compatibility with original hoods
  12. lack of basic dust and moisture protection (in Nikon 85 / 1.8G, for example, there is rubber lens mount seal)
  13. tangible effect of 'Focus Breathing' (changes in viewing angle during focusing)
  14. poor instruction (jambs indicating the minimum aperture, lack of information about the type of hood, etc.)
  15. there is no tag for working in the infrared spectrum, the depth of field and focusing distances are small
  16. there may be incompatibility with some cameras and / or teleconverters (no exact data)
  17. lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of optical distortion (distortion, vignetting etc.)
  18. lack of lens profile in popular RAW converters (perhaps this is only a temporary drawback)
  19. the survivability of this lens and the variation in quality are unknown. Little information on Yongnuo Certified Lens Service Centers
  20. certain imperfections in the image (poor sharpness at F / 2.0 at the corners and edges of the image, poor resistance to lateral light, a set of optical distortions characteristic of lenses of this kind). Particularly noteworthy is the whitish veil in the center of the frame on little contrasting scenes and covered apertures

  • Alex

    will autofocus work on nikon z6?

    • Arkady Shapoval

      It should work with the appropriate adapter, but there is no reliable data.

  • Marina

    Good afternoon! I have a bunch of Nikon d40 and this lens. I can't understand when autofocusing - the camera simply does not allow pressing the shutter button, focusing well, for a very long time. I use it only in manual mode, otherwise it just takes a lot of time.
    Tell me what am I doing wrong? In manual mode, the picture is often blurry, but in cars this is such garbage ((

    • Arkady Shapoval

      Perhaps some kind of problem with the lens, still these are Chinese products. Try another AF-C focus mode.

      • Marina

        Yes, it works in this mode. But it smears, maybe the focus "runs"

  • Oleh

    Having bought a Danish ob'ktiv if koristuvavsya crop D7000.
    Cool, ale - nі.
    1. To be afraid of a backlight
    2. Subject to the norms, and only to photograph them, take people to the highest standards, and be brought to stand far away from the model.
    3. If you are far away from the model, the bokeh is not the same, as you want it
    4. Knowledge on short showcases, more minimal tremor, and even everything is irrevocably oiled.
    Immediately think about selling yogo ... docks do not switch to the D610 frame
    Now the tse of my loves is an asset for portraits on the street.

    But one thing - shvidko viyshov in the fret change between the focusing modes, and that at a time even more rarely, ale, if you don't want to focus, as long as you don't move the pump.

    • B. R. P.

      Three quarters of another point - the price of obvious speech is not only about the object, but about the other in focus.

    • Alexander

      On the second and third point, alas, but at such focal lengths (85-100-135mm) people are not photographed at full height. It is customary to use focal data when shooting face and shoulder portraits, 50mm with waist portraits, 35mm can already be shot in full height. Looking ahead, I’ll say that in amateur photography there are no strict rules, of course, shoot what you want and how you want. But if you want to get the expected result, you should still follow some rules. Your case is a great example.

      • Vyacheslav

        Are these focal lengths for a crop or full frame?

        • B. R. P.

          For a full frame.

      • Andrei

        You will excuse me, of course, but I could not pass by. How is it that they do not shoot full-length portraits at focal lengths larger than 35mm !?
        I just think that the ideal for a height is 135mm .. (if there is somewhere to go with it), but as categorically as you write - I was already speechless.

        • Eugene

          And where will you go at the same time? Over 20 meters? Very convenient for the growth. It is especially convenient to communicate with the model ...

  • Taras

    The Canon ET-65 III Hood fits perfectly, but it still doesn't help much from backlight! I did not test it in the field, the picture does not shine with contrast in not sunny weather ...

  • Distribute

    Good afternoon, I have a Nikon d7500 35mm 1.8 50 1.8 sigma 17-50 2.8, after reviewing and watching a video on your YouTube channel I can't decide which one to sell and replace with this
    yongnuo 100mm f / 2 and will it open on my camera?

    • B. R. P.

      Are you sure that you need to replace something? How are you going to use 100mm, what is the problem with the existing lenses?

  • Distribute

    17-50 on trips and as a staff member
    as a rule, I take it for walks outside the street and 35.
    50 specialized when we are planning something staged (this summer% 70 used it and 17-50).
    And I seem to be using everything, but something is missing or something is superfluous.
    Having this 100mm, judging by the review, you can try to feel something a little more artistic and beautifully soapy-boxy than 50mm

    • Oleg

      1. Do not sell anything, buy 100 mm, think after use whether you need to sell something.
      2. Before buying 100 mm, refuse to use one of the two lenses and see if the other replaces it sufficiently: Take only 35 mm and shoot with it what was usually shot at 17-50, then take 17-50 and shoot something that you filmed earlier at 35. Then look at the photo and evaluate, think: are you ready to give up one of the lenses.

      Because all the clear advice on what to leave will be based on individual preferences. And the taste, as you know, as well as the color of the comrades.

    • Natalia

      Bought 100mm in the end? I also have Nikon d7500, sigma 17-50 and Nikon 35 mm. I'm looking at 85 and 100mm now. Do you like this lens?

  • Distribute

    Well, I decided to buy this miracle, but it is not on sale (under nikon), only canon, but I don’t really want to wait from China ...

  • Oleksandr

    Є on OLH, you can take a look at the following:


  • Arkady Shapoval

    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

  • Ilya

    On the d780 in live view mode, the focus starts to drive back and forth, but it cannot catch on. The firmware was updated to the latest current one, but it did not help ... unfortunately.
    There are no problems through the viewfinder.

  • Maria

    May I ask your advice? Thank you in advance.
    I am considering a budget lens 85-100 mm.
    which lens would you choose (outdoor portrait photography with the Nikon 610)
    meike 85 mm 1/8 or Yongnuo 100 mm F2 F2N ?

    • Arkady Shapoval

      boo. 85/1.8D, then 100/2, then Mnik

  • Vadim

    I'm waiting for the delivery of this lens the other day. For amateur and semi-professional use, I'm going to use it with the D700. I hope that there will be no problems with autofocus.
