Copper Adapter K&F Concept Lens Mount Adapter Compatible with AI Lens to Sony NEX E-Mount Camera Body

This my second K&F adapter and it's as great as the first one. I've seen prior versions without copper enhancement were not as high quality but I cannot attest to that as I do not have them but I can confirm the versions with them are solid choice for adapting lenses.

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.

Excellent quality. Professional fit and finish.

Careful. The product description says this adapter accepts Nikon AI mount lenses. Not true. Had to return. Too bad, since the construction seems solid. I guess it's made to work with newer generation lenses.
