Used this to mount Nikon AIS manual focus lenses to Sony A7II. It worked very well. Nice tight fit on both lens and camera body. Great to be using lenses again after 20 years. Excellent product. I bought K&F Model KF06.309. Telling you this because vendors description was not clear whether it would work.

This requires a Nikon lens with its own aperture ring. Very sturdy and precise, no problems in use.
