Fotodiox Pro Announces Nikon to Sony FUSION Adapter for Full Function Control

Fotodiox Pro, creator and distributor of several lines of specialty solutions for videography, cinematography and photography, has announced their new Nikon to Sony FUSION Lens Adapter. Available now on, the Nikon to Sony FUSION Adapter allows photographers to mount Nikon lenses onto Sony cameras and maintain electronic communication between the two, delivering decades of legendary Nikon imaging expertise to the hands of full frame or APS-C Sony E-Mount camera users.

“The Nikon to Sony FUSION Adapter is truly the first of its kind, and we couldn’t be more excited to share it with our customers,” said Bohus Blahut, marketing director for Fotodiox Pro. “What makes it such a breakthrough is the presence of FUSION Drive – a built-in motor that physically moves the lens’ internal aperture control lever. Nikon lenses are notorious for maintaining mechanical aperture control while many other functions are electronic, but FUSION Drive, which we built for the very first time for this Nikon to Sony FUSION Adapter, solves that issue.”

By installing the Nikon to Sony FUSION Adapter on a full frame or APS-C Sony E-Mount camera, Nikon AF-I and AF-S lenses gain auto-focus, full aperture control for Auto / Aperture Priority / Program AE modes, EXIF data transmission (on compatible models) and image stabilization (on compatible models). The Nikon to Sony FUSION Adapter is also compatible with fully manual vintage Nikon F lenses as a manual adapter.

Photographers are advised that the FUSION Adapter is designed to work best with newer Sony cameras that have “Phase Detection Auto Focus”, such as Sony a7, a7II, a7rII, a6000, a6300 and a6500 cameras. The Nikon to Sony FUSION Adapter’s performance will be significantly slower with older Sony cameras that rely solely on “Contrast Detection Auto Focus”.

    Sounds exciting
    The one unanswered question I have is will this work with teleconverters, both Nikon and 3rd party ????

  • Mike

    This is cool. Say bye bye to your already short lived Sony batteries though. With Nikon’s move to E lenses, this makes sense for easier adaptability for mirrorless cameras too.

  • Elvin Tan

    looks like its an oem-ed commlite (see video comments)

    • animalsbybarry

      This does not appear to be the same Comlite/Vello adapter
      That one does not work too good

      • Yes, this appears to be a brand new adapter/model.

      • Elvin Tan

        The comment by fotodiox in the video says “Hi Brian, we partnered with Commlite to create our FUSION adapter. Ours includes the most current firmware.” (Which essentially means they oem it, and have the most current v4 firmware)

              “Hi Programmer Qn, the Nikon to Sony FUSION ships with the most up-to-date firmware. While its currently not possible for customers to update the adapter’s firmware, we’re exploring ways to do this in the near future.”

              At least the commlite ones were upgradable

      • ninpou_kobanashi

        “That one does not work too good”
        That’s an understatement. I returned two; they suck so bad.

        • Sharpest Light Limited

          What camera did you use with? All comes with latest adapter firmware?

          • ninpou_kobanashi

            Yes, latest firmware on everything (body, lenses, commlite unit). using a Sony A7RII when I tested it. The last time I tried was August of this year.

            I totally wanted it to work, but in the end I was afraid it was going to damage my camera or lens. Sometimes, the aperture would close and open continuously, rapidly and the unit would lock up.

            I’d read the reviews on the BHPhoto site and judge for yourself. Also, the initial version was so bad, and go so many bad reviews, that BHPhoto discontinued the product and created a new product entry in the catalog (for the updated firmware version).

            It’s possible that the newest collaboration firmware is better, but I’ll be waiting for more feedback this time around.

            • Citizen Kang

              I have the Commlite and use it with my a6300 (it just hunts on my a7s and a6000), it’s a mixed bag. With my Nikon 70-200 f/2.8 VRII, it works very well. With my Sigma 85mm it OK; with the version 3 firmware, Sigma 35mm Art it’s pretty good. With the version 4 firmware, it doesn’t work at all as I recall. There is a clear correlation between the amount of light the sensor receives and it’s AF performance. In anything less than ideal light, I wouldn’t bother with the adapter no matter how fast the lens happens to be. Out of all the Sony cameras currently available, I hear the a6300 performs the best. The a7rII is a step down, but not a huge step (again, from what I hear since I don’t own one yet). I have slightly higher hopes that the a6500 will perform a bit better, but I’m not expecting miracles.

  • MRomine

    What about eye-AF is that maintained with this adapter?

    • Sharpest Light Limited

      Does not have eye-AF

  • MonkeySpanner

    Don’t need Nikon mirrorless now. 😉

  • Hopefully this means that an F-to-m43 ‘smart’ adaptor is in the works.

    • I emailed Fotodiox to ask if they were working on or had plans for an F-to-m43 ‘smart’ adaptor. They replied within a day to state that they had no plans for making one.


    I have discovered that if I put my Nikon AF-S lens on a Nikon DSLR camera, I have all of these advanced functions — without the need for an adapter! It works really well — and I get great image quality. I’m surprised no one else has discovered this…

    • Sawyerspadre

      And, you don’t need to buy a Sony body, or an adapter.

      • Cesar Sales

        And you get better IQ without all that extra glass and tolerances in between!

        • speedy fisher

          What extra glass?

    • longzoom

      You are not a romantic! It is so trivial to put Nikkor lens on Nikon! There will be no lettering SONY on the camera! Without it people will think you are came from wild province! Come on, why do I need to lecture you?

      • Kelly

        That’s ok. The sensor will still be Sony, lol. 🙂

        • Stormy Llama

          But the SNR firmware will be Nikon in the Nikon body, check mate. 😛

    • Spy Black

      …except there is no Nikon body like the A7S at this time. 😉

      • HD10

        … and that is why one will have to contend with poor camera controls and short battery life. But in due time, Sony will address this so Nikon would best release its mirrorless F-mount FX and DX in 2017.

      • AnotherView

        Yeah, well I get that Sony sensors are among the best available – if not THE best – but otherwise Sony bodies, mechanics and limited lens selection fall well short of Canikon. My one and only foray into the mirrorless world was with the V1, and that was enough to convince me that mirrorless has a l-o-n-g way to go before it can compete with a traditional DSLR, if ever.

        • speedy fisher

          Hah! My only time driving a car was with a Model T Ford, and that was enough to convince me that cars are not suitable modern transportation.

          • Piooof

            Well, that’s certainly true, they emit far too much fossil carbon dioxide. 😛

          • AnotherView

            I don’t understand how any serious photographers can carefully compose an image by looking an LCD screen in the bright light/sunshine — let alone focus accurately. Yeah, so I’m old school…

            • Wesley

              Eye-level viewfinders (which the V1 has), focus magnification, and focus peaking.

    • because Nikon shoots 1080p (120) in S-log and Pro Res…..
      A see the downfall in your sarcasm…

    • ninpou_kobanashi

      Yes, but try as you might, you’re not getting slog2

  • catinhat

    Looks perfect for those looking for an ergonomic challenge.

  • Tieu Ngao

    We need a review to see if it affects the IQ related factors like: sharpness, contrast, color, etc.

    • Citizen Kang

      It shouldn’t considering there is no glass in this adapter. Now, the tolerances are another issue, but that is another matter altogether.

    • ninpou_kobanashi

      It’s hollow.

  • Tieu Ngao

    If it works like native lenses then Nikon has to work harder to prevent people from switching brand. And that’s good for the industry as a whole.

    • Eric Calabros

      Canon users have full control adapter since..I don’t know exact date, but it was long time ago. Canon panicked and released a FF mirrorless? No.

      • HD10

        Canon may not have released an FF mirrorless because it was not prepared to do so. Such adapters surely added to the worry lines of a good number of Canon executives considering that the Sony A7 series has much better sensors than Canon and made it easier for the Canon faithful to try a Sony camera. Even if Canon may not have panicked to releasing a FF mirrorless, I think it is a given that with such adapters now in the market, Canon is under even more greater pressure to do so sooner rather than later.

    • Antonio

      Better not to be that optimistic about such a wonderful performance…if it is the same as the Vello it is far from such a perfection and even the manufacturer’s “compatibility list” doesn’t include some AF-S lenses like the 70-300 VR and says that the 105 2.8 VR Macro doesn’t do AF or does the slow way.

  • HD10

    The acid test of such adapters will be how well it will enable accurate AF-C operations while shooting at high frame rates as Sony does not have any FE lenses longer than 200mm . Perhaps accurate AF-C operation of a Nikkor F-mount on an A7 body is a bridge too far but most I suspect will settle for a bit less than this.

    The ability to adapt the Nikkor F-mount lenses can only improve as Nikon releases more E lenses. There will however still be far more Canon lenses that can be easily adapted to a Sony body while retaining most of the lens functionalities.

    I do wonder how many Canon lens owners have acquired a Sony camera and adapted their Canon lenses to this. The upside for doing this would be much improved image quality. The downside is poor camera controls, short battery life and possible issues cause by the adapter’s mount tolerance and alignment.

    Admin, please consider creating a simple poll to see how many current Nikon F-mount owners would buy a Sony A7 body if a much improved adapter is made that will enable the use of Nikkor D G and E mount lenses on a Sony A7 body? Thereafter, it would be interesting to see which particular lenses do they have an interest in using an adapter with.

    Let me start. until Nikon releases a mirrorless F-mount high-resolution FX body with an articulating touch screen with an electronic first curtain, I will consider getting the A7R II and intend to use this primarily with my PC-E and f/1.8 (less so with the much heavier f/1.4) prime lenses.

    • Eric Calabros

      – Beyond 200mm phase detection on sensor is a big challenge. No matter what lens you use.
      – Adapter can’t change the fact that AF-S mechanism is made to work best with PDAF, not CDAF that Sony still use.

      • HD10

        This will be less of an issue with the Sony A7 bodies where the sensor has OSPDAF.

        As to the suitability of the OSPDAF with long lenses, I have heard about this but do wonder whether this is accurate since the Nikon One Series which has OSPDAF does quite well up to 300mm using the native Nikkor 1 70-300mm f/4.5-5.6 VR lense despite the 2.7x crop factor. The performance review of this lens on BH Photo is quite good.

        • Eric Calabros

          DOF of 300mm at f/5.6 on a 1 inch sensor hide focus errors.

          • HD10

            I am aware of that but still raised this point because while the Nikon 1 apparent DOF may be deeper due to the small sized sensor, this also yields a 2.7x crop factor that means that the field of view of a Nikon 1 lens 300mm is 810mm. Even with such deep DOF, I see that it is possible to get blurred backgrounds when shooting near-sited objects with far-sited backgrounds. I have observed that the higher the resolution, the greater the need for accurate AF. Reliance on hyperfocal distance focusing yielded unsatisfactory results. The 20.8mp pixel density of the Nikon J5 means that AF is critical when working with long lenses as it is possible to get unsatisfactory results despite the deeper DOF if AF is not accurate. The bottom line is that I am unconvinced that OSPDAF will not work well with lenses longer than 200mm.

            • Eric Calabros

              Nikon P&S camera P900 focuses at 2000mm. Its not “Does it focus?” question. Its how it does tracking question. Google A7rii+focus hunting.

            • HD10

              Were you referring to native FE lenses? It would be unrealistic to expect the A7Rii OSPDAF AF-C to work flawlessly when using adapters and non-native longer than 200mm lenses.

            • Max

              I saw a p900 in the camera store yesterday – it’s huge! For a bridge camera

    • MB

      24-240 and 70-300 are longer than 200 …

  • Eric Calabros

    That 17-35 lens really need an upgrade

    • fanboy fagz

      doesnt need an upgrade more than it needs a reasonable price. at $2000, those fuckers are on crack there.

  • HD10

    Sigma, Tamron and Tokina are better positioned to make this type of adapters than anyone else. Beyond general functionality, the lens manufacturers can ensure that its adapter will be fully tested with their lenses. Sigma has done this with Canon. The additional difficulty in doing this with non-E Nikkor lenses certainly could be one reason. But the more likely reason is likely that the market for such adapters may shrink once Nikon releases an F-mount FX and DX camera.

  • Sharpest Light Limited

    Any compatible list? If there is, that will answer the question of brand new or OEM.

  • Robbie Green

    With the interest in adaptors like these for the Sony A7 series, I have to wonder if Nikon’s eventual full-frame mirrorless offering might be a similar design to the Sony A99 series. Sony believes in it enough apparently to resurrect A mount and go after Nikon’s sports shooters.

    With all the F mount glass out there, and with the obvious interest in mirrorless, it seems like a no brainer.

  • MB

    If this Fotodiox adapter is 350$ than Nikon adapter for a new and much anticipated Nikon full frame mirrorless camera would be at least 1500$, and I am sure Nikon will (unlike Sony) do everything to make it impossible for 3rd parties to make compatible lenses or adapters … so our only hope would be for Nikon to make full frame mirrorless camera with regular F mount …

  • Matt

    If this is for real I’m going to buy a sony FF as my next camera. But I’ll wait for reviews on this adapter – that AF performance looked very promising!

  • animalsbybarry

    Fotodiox got back to
    This will not work with TC or 3rd party

    It most like will not work with teleconverters, the AF will be most likely be hunting for ever, as for third party lenses they do worse then native lenses it varies from lens to lens but performance seems to be worse with them.

  • jmb2560

    @admin: any rumor on what Nikon will announce at CES? it’s less than two months away

    • no, nothing for now – I am guessing a new Nikon 1 J6

      • jmb2560

        Thanks. Nothing on a 820 or like… and nothing on a FX mirrorless (yet) to compete against Sony. I hope Nikon has more to announce than just a J6.

    • Fly Moon

      They will RE-launch the DL cameras!!

      • jmb2560

        LOL Yesssss!

    • Max

      They’re going to announce Key Mission Gear i. It’s a pouch, lens cleaner kit and an additional mounting piece that can be attached onto the Nikon TF45 bike handlebar mount for the KeyMission cameras. It will be available in black, carbon, charcoal, silver or red. They will also announce a strap for the KM Gear pouch.
      My only concern is whether one would be able to get working third party straps for this pouch.

  • T.I.M

    For $100 more you can get a brand new D5200 (24MP DX) camera.

  • manattan

    I would prefer a Sony A7rii with a native F-mount. That way I get to use all of that great Nikon glass

  • kerryphillips

    Well, I thought it’d be fun to get my awesome collection of NIkkor Lenses working on my Sony body and I made the large mistake of thinking the Vello Adaptor V4 (same as Commlite) would work with most lenses I have, but it even locks up my Sony A7R2 using my 17-35mm 2.8 to an amazing amount of frustration, and, looking like a complete putz. Totally embarrassing waste of time. I want my D810 back

  • Lan Jay

    Any reply from the Steel Chen?
    This guy has been disappeared on the China forum since this July. I wonder if the final product will ever be released……….

  • ninpou_kobanashi

    1.5/5 stars so far on Amazon. Not looking good, looking exactly like the Commlite clone.

  • Refuz Tosay

    If this works perfectly it can basically run NIkon out of the camera business. Relegating them to a lens maker. Good enough for those fools – sticking with the same shite menu system for 30 years. All Nikon software/GUI sucks – and they wouldn’t even have a decent sensor without sourcing from Sony. And don’t forget how Nikon strips out features from mid range bodies to protect the more expensive models even though the hardware is the same. They need to open up their operating system to 3rd party developers to create and sell apps/GUI/menu systems – and replace that POS SnapBridge.
