Review: Excellent - Excellent adapter. Now i can use my old nikon lenses on fuji.
Review: Works great adapting Nikon F lenses to Fujifilm X-T20 - I purchased a Fotsay Minolta MD, Canon FD, and Nikon F mount to Fuji X-Mount adapter for use on my Fujifilm X-T20 and my opinion is the same on all three, so I am using the same review for all three. These Fotsay adapters work just as well as the higher priced adapters. Sure, they may lack some fancy anodized trim, and rely on textured metal grips instead of a rubber grip, but in terms of adaptability, I've had no issues. Each of these adapters mounts correctly to my X-T20 and each classic lens I've used and I've had no issues. The lenses and the adapter are neither too tight to get stuck, or too loose to fall off or cause light leaks. Since none of these have any optical elements in them, there is no degradation in image quality, and they all focus to infinity correctly. Of course, you need to set the camera to work with no lens (I forget the setting in the camera, but its in the manual) and you need to set the camera to Manual focus, but I find the focus peaking feature of the X-T20 to work really well with these adapters and manual focus lenses. A note about this Nikon adapter is that it will not control the aperture on "G" lenses. In a nutshell, you can spend more (sometimes a lot more) on other brands adapters, and get a nicer looking one that maybe has a nicer grip, or save yourself some money and just get these. If I had one suggestion, its that I wish there was a Helicoid version of these three mounts. I have the Fotsay M42 -> Fuji X-mount Helicoid adapter and it works really well. I wish they had versions of these with that feature.

## Questions & Answers

**Q: Can you place a x-fujinon 1:1.9 f=50mm fm lens to this mount?**
A: No.  This is for mounting lenses originally made for Pentax/Praktica slr film cameras with a 42 millemeter thread mount to modern Fuji "X" series bodies.

**Q: Does the adapter change the functional focal length of the lens?**
A: The earlier answers confuse focal length with angle of view. These are two different things. Focal length is not changed at all by either the adapter or the camera; you would need additional optics to do that. What does change is the effective angle of view, because the APS-C sensor in the camera is smaller than a 35mm film frame. So, yes, in terms of angle of view, a 50mm lens ends up giving you a narrower angle of view comparable to a 75mm lens due to the smaller sensor, but that's not a change of focal length.

**Q: Will this adapter work with fuji xt1 and can you mount a holga pinhole lens cap which fits a canon ef adapter on it?**
A: The adaptor should work on any of the x mount series (they all use the same fitting) but I do not know directly about putting a holga pinhole cap on the other end. If the cap fits the Canon gear, it probably will work, but you will have to try it to be sure.

**Q: does it work with fujifilm xt 20?**
A: You will have to go into the camera's menu and look for a shoot without lens option.

### ⭐⭐⭐⭐⭐ Excellent

Excellent adapter. Now i can use my old nikon lenses on fuji.

### ⭐⭐⭐⭐⭐ Works great adapting Nikon F lenses to Fujifilm X-T20
*by M***N on 2 May 2018*

### ⭐⭐⭐⭐⭐ Fantastic
*by J***L on 1 April 2014*

I'm using this on an X-T1 and it works great. Nikons sensor/film plane is way further back in the camera due to the mirror so there's no magic optical conversion or extraneous glass needed for this adapter. It just moves the lens outwards the proper distance to the Fuji sensor and bam... literally the *exact* same as if it were mounted on a Nikon DX sensor. So it doesn't introduce any fringing, vignetting, softness, or anything else outside of what the lens would normally produce. Using this with an X-T1 with manual focus peaking is a dream come true. Don't get me wrong, I have Fuji glass and I love it. But theres something so satisfying about having the solid tactile feel of the focus and aperture rings. I can focus soooo much faster with this than I can doing manual focus with Fuji's 'focus by wire' system. Five minutes after shooting and I was checking craiglist trying to find old Nikon glass to use for full time shooting. The ONLY complaint I have about this is tolerances for mounting the lens to the adapter are probably off by a few 1000th's. Because of this, it's a little firm twisting a lens on, not buttery smooth like on a real Nikon body. Not really bad for the lens, but it does put a bit of torque on the mount if you still have it on the camera. Because of this, if you have multiple Nikon lenses, I would recommend either taking the adapter off the body before swapping lenses or just buying an adapter for each lens you have because they're so cheap. Lastly, I was a little worried looking at pictures and trying to gauge material finish and quality but when I received it I found that it's machined from a solid hunk of aluminum. In fact, it's better quality than the old Nikkor 50mm lens that I put on it. At the time of this writing there are 3 nearly identical adapters on Amazon, this one costing half as much. I'm almost positive after receiving it and looking at the pictures again that these are identical and just re-branded between different companies. If you're on the fence like I was, go for whichever one is cheaper at the moment.
