Great value after trying to locate one of the adapters. Fits perfectly and has saved me £££ instead of purchasing new lenses.

Used this to mount Canon FD manual focus lenses to Sony A7II. It worked very well. Nice tight fit on both lens and camera body. Excellent product. Note manual focus and manual aperture select is required. I believe the reference to "copper" is actually refering to the use of brass material. This is supposed to be the improved Mark II version of K&F,s adaptor.

This is K&F Concepts 2nd version of their FD to NEX mount. This one currently doesn't have as many reviews, but is superior to the first - I've owned both.Quality and compatibility are a given at this point - K&F nailed this on the first version. The design improvements made to this version include the chromed camera mounting bayonet, the application of anti-reflective coating on the inside, and adding an ever so slightly amount of thickness to the top of the adapter. There's also some improvement in how the lock ring functions.As a result - the camera mounting mechanism is a little sturdier, light won't reflect off the inside of the adapter and add aberrations to photos (rare case), and there is slightly less beyond infinite focus which gives you a tiny bit of additional minimum focus distance. The ability to focus beyond infinity was never a strength of the first version, and while improved on this version, could still be better.Get this version over the other one. It's better.
