have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

Solid build quality. I wish it had a few more stops though. The assembly of the Fuji X-T20 body and the lenses Nikkor 50mm f/1.8G and Tokina 12-28 f/4 went smoothly. Time to take some photos!

Looks just like the disposable fuji cameras. Lightweight with a screen on the front and back. Okay clarity, but not great pixels. Works well for my niece to record videos.

It does what it promises; it allows your Dx lenses to work on the Fuji X system, for me on the X-T30. Of course, the lens is manual only and data is limited; the aperture had to be guessed from the "clicks" when turning the ring. I found it worked much better with my fast prime lens (image is of a 50mm F1.8). My 18-200 F3.5-5.6 didn't work nearly as well, especially the aperture control. Overall I would recommend it as long as you understand what you are getting.

The darker version of this is utterly indispensible for LOG video with high ISOs forced by the camera, combined with fast lenses you'd like to open up for depth control/"bokeh". And only the wildly expensive PolarPro has a similar option. And while I suppose the PolarPro might be somehow better - I'm simply not rich enough to find out! In the meantime the K&F has served very well. I use this primarily on a Fuji X-T3 with f1.2 and f1.4 prime lenses, shooting F-LOG at the required minimum 640 ISO. Secondarily on a Fuji X-H1 (800 ISO LOG!) and even a Nikon D750 for occasional stills.

Hey K&F! Do you read reviews? I wish you offered the dark version in smaller diameters (e.g. 62mm) as I'd get another to use with the majority of my prime lenses with no step-up ring.

bought it to use some of my Nikon lenses on my Fuji X-E3, specifically my Sigma ultra wide-angle zoom and my 105mm micro-Nikkor. The adapter's two-tone silver and black metal construction gives it a solid feel and also complements my camera's black and silver color scheme. Focusing is a little tricky, but becomes a lot easier when Focus Tip is enabled on the camera. Just make sure you change your camera settings to "shoot without a lens" and flip the physical switch on the camera to manual focus. I love my little Fuji and was reluctant to take out my D7000 to use some of my specialty Nikkor lenses. I wasn't keen on the prospect of selling my Nikkor lenses to replace them with Fujinon lenses. This adapter gives me the best of both worlds. A little more aperture control would be nice, but other than that I'm quite happy!

I bought this part to be able to use my Lensbaby composer on my Fuji cameras as well. The adapter makes a valuable and well-made impression. It looks stable and works as expected. Since everything is set manually on the Composer anyway, I'm not interested in the lack of the autofocus story. Very useful for me at this price.

Use it to use older lenses on my FUJI.
