Awesome!AMAZON thanks you.

I got this adaptor to adapt my old MF nikon lenses onto my Fuji x-s10. I got the adaptor that is for "g" lenses (it has an aperture ring) since I also own Nikon g lenses. There was some question of whether it would work with MF lenses or not. The answer is YES!To use it with MF lenses, you have two options for controlling the aperture. Option 1) set the adaptor aperture ring to it's widest setting, and use your lens aperture ring to control your aperture. Option 2) set your lens aperture to it's smallest setting (f/22 or f/32), and use the adaptor aperture ring to adjust your aperture. NOTE: option 1 is probably the best option in most situations for reasons too complicated to get into here.The fit of the adaptor is perfect. It is tight, both on the camera and at the lens, however I don't think it is too tight. There is extremely minimal wobble. I have to torque on the lens to feel it shake.The adaptor quality seems very good. The aperture ring turns smoothly with nicely dampened clicks. The box it came in is a nice touch.I'm very happy with the purchase.

Build and functionality is great!

These adapters are actually an improvement in quality over the previous design.They look pretty good and they FIT very well. There is no lateral movement and no significant rotational play.The fit and finish on these is excellent. The aperture ring has the right feel. It's not loose. Moves smoothly and does have a click you can feel as you operate the ring.The only thing I would "improve" is the short throw of the aperture ring. . . but that might not actually happen because this depends on the throw of the aperture lever on the lens itself.

Using it on my Fuji Xt-5. I had couple of premier tier Nikon lenses and was looking ways to use them on Fuji. This converter is really good, gets the job done. aperture control and focusing is manual, but that's the way it is. I use it for outdoors and indoors photoahoot. Image quality is superb as well.

Maybe I got a bad one but if the fit is typical, avoid this at any price. Fitting the lens on was NOT smooth as it required quite an effort to turn and I could hear the grinding of mating surfaces, definitely not how it should be. I've never had such an uneasy experience mounting any lens on any direct camera mounts. The horror of a stuck lens, or worse yet, a damaged lens swirled in my head as I tried this adapter. Never again!

Works perfectly with my x-t30 II X mount and my old Nikkor lens.

I'm using this on a Fuji X-S10 to adapt some early 70's Nikon lenses. The adapter fit the camera body just fine. However the lens mount side was extremely tight. I thought I had purchased the wrong adapter at first! It took much more force to mount a lens than I'm comfortable with on a camera. I'm not sure if this is normal or if I just got a bad copy.This is the more versatile of the adapters they sell, allowing you to use lenses with an aperture ring like my old ones as well as newer lenses with no ring on the lens. There is a ring on the adapter for this. If you are using both new and older lenses this would be the adapter to go with. But I'm finding I'm continually changing the ring on the adapter accidentally, it would be nice if you could lock it in place if you don't need it.I also find I'm hitting the lens release button when I'm reaching for the aperture ring on my lens.I'm still on the fence about requesting a replacement or just returning it and purchasing a different model. It really should not require that much force to click the lens in to place.
