Description

Mirrorless cameras aren't only revolutionary because of their compact size; they're even more versatile for mounting lenses than their full-sized counterparts! Fotodiox offers strong support for mirrorless camera platforms with hundreds of options for mounting both modern and vintage lenses. Our adapters deliver infinity focus, manual aperture control, and a sturdy build for lasting quality. Compatible Fuji X-Mount Cameras - Popular models include: FUJI X-A1, X-A2, X-A3, X-A5, X-A10, X-E1, X-E2, X-E2s, X-E3, X-H1, X-M1, X-Pro1, X-Pro2, X-T1, X-T2, X-T3, X-T10, X-T20, X-T100 Note: • This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. • If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop. All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.

    • It works great and the larger section has plate for Arca mount.
Size: Pentax 6x7 Style: PRO
All three mounts on this 2 section adapter have the right fit. Most importantly, the sensor depth offset works correctly. The distance marks on the lens still work. I used a Haoge macro focusing rail for a lens handle attached to the larger adapter. It is a sturdy handle with the right balance. The long Arca rail allows me to offset the nearly 1Kg imbalance between the camera (Fuji XT-5) and lens on the tripod. ... show more

    • The rest is on you
Size: Nikon F G-Type Style: PRO
I've never really manually focused a camera. Sure I have an 8mm fisheye that lacks AF, but at 8mm, just about everything is in focus. That being said, I had that same 8mm lens, a 85mm/1.8 D, a 10-20mm/3.5 and a 18-300VR beast for my Nikon, and so little glass for my new X-E2. While I didn't plan on using my 18-300VR at on with this, and I don't plan on using my 10-20mm/3.5 much on my Fuji, the other two lenses seemed ripe for experimentation. The mount attaches firmly and without and grittiness of scraping. Likewise the lens attach to it without an issues, and everything is secure. The overall fit and finish inspires confidence. There's not much to it, as it's basically a machined alumninum tube, albeit with a few tricks up its sleeve. For one, it supports "G" lenses (those without aperture rings). The two lenses I wanted to experiment with do have old school aperture rings, and they work well. Either you can let this adapter control things (as it would for a G lens), or use the ring on the lens. Either way, it worked well, though the aperture adjustments on this adapter are very basic, so you won't have as much control as you would with an aperture ring of the controls on a modern Nikon camera. Just to be clear what work means, there's no data going to the camera, so it never knows the aperture, there's no lens correction, and focusing is manual. It was relatively easy, even for a novice like me, to manually focus even the 85mm/1.8 D at f/1.8 on the X-E2. I enabled focus peaking, and I also used the distance scale. The latter got me in the ballpark, and the former helped me fine tune things. Honestly, I think I could get rather proficient with practice, but for now there is no muscle memory, and it's best for deliberate moments, rather than on the fly shooting, which is nice for a change anyway. I'd set your expectations based on your previous experience, though in the end, I think most if not all users can have great results, with the right lenses. I'll try to post sample images shortly. ... show more

    • Great product at a great price
Size: Nikon F Style: Standard
Bought this lens mount converter as a low cost way to test how my old Nikon AIS lenses would work on my new Fuji X-T1 camera. I figured if it worked, I would spring for one of the more expensive Metabones adaptors. After testing it for about a week, I have am so pleased with the results, that I find that I'm using it much more than expected. Using the focus peaking with this adaptor and a verity of my old Nikon glass allowed me to focus very quickly while achieving amazingly sharp images. Oh, and what happened to buying the Metaboans? Well, there is no need. This adaptor is very well made with fill metal construction. The fit is tight with no light leak and the lenses feel solidly mounted, even upto my 70-200mm. The adaptor looks good on the camera and is not to tall to push the lens out too far. I did borough the Metaboans from a friend shortly after, and yes, it is a higher quality product, but the function is identical. It is like the difference between a Porsche and a Lamborghini. There is one small drawback that I should mention, although it is a pure cosmetic issue. When you mount the lens on the adaptor, the lens is about 1/8 of a rotation from having the aperture and focus indicator at the top. It doesn't affect the function, but it would have looked a bit nicer. Maybe there is an adjustment for this, but I have not found it...yet. Overall, this is a very good product at an excellent price. ... show more

    • It WORKS!!
Size: Nikon F G-Type Style: PRO
This lens adapter enables the use of NIKON (Nikkor) lenses on the FUJIFILM X-mount series of compact cameras. It works perfectly on my Fuji X-T1. The metal tube seems very solid and machined well. The mount lines up and slides smoothly onto the Fuji body with a reassuring click. Lenses mount as they would on the Nikon body on the receiving end, also very smoothly with no play. There is absolutely no movement or sense of mis-alignment on the copy I have. Focus using the Nikkors seems spot-on across the plane. It does of course extend the lens even farther from the camera and makes most of my Nikkors look ridiculously long and huge on the small Fuji body...but it works, and well. Not sure why the little ring is such a bright blue, its a bit distracting and showy, but OK. Of course, you have to FOCUS MANUALLY, there is no electronic contact with the third-party lenses to the Fuji camera. For newer Nikon lenses (G-type and above) you can set the aperture using the blue ring on the adapter. At far left is wide-open, at far-right is fully stopped-down. Don't know why there are only FOUR CLICKS between wideopen and stopped down fully. You can however move the ring slightly and get in-between these indented stops, but its a bit of a pain, and you don't know what f/stop its on at all. I've noticed the Canon version of this adapter appears to have several more "stops" on this ring--not sure why the Nikon version has so few. You can use your camera in Aperture-Priority mode and let the camera do some of the AE work if you want. Also, you can use older Nikon lenses as well (ones with aperture rings on the lens). I then put the adapter's ring on max (stopped-down) and use the lens' aperture ring to change apertures--works fine, and you then have all the clicks available on the lens. With G-lenses you just have to guess where you have the aperture. I generally just shoot wide open, or stop it down just a tad. I'm pretty happy for the price though. It works, its sharp, and I can use every Nikon glass I own (from 8mm fisheye to 300 f/2.8) on my Fuji body, if I so desire. So far I am happy using a few primes in particular such as my Tamron 90mm Macro, a 50 and 85 f/1.4, Tokina 10-17mm, etc. I'd suggest holding any heavy lens by the lens, and not put too much weight on your Fuji body mount! ... show more
