K&F Concept Lens Mount Adapter FD-NEX Copper Adapter For Canon FD FL Lens to Sony NEX E-Mount Camera for Sony Alpha NEX-7 NEX-6 NEX-5N NEX-5 NEX-C3 NEX-3

This is the 2nd revision of the K&F adaptor. I also own the first. The 2nd revision is a significant improvement on the already stellar original. The adaptor feels sturdier and a bit heavier (in a good way). the camera mount is now made of chrome and the inside is now coated to prevent internal reflections. The first version is still available for a couple of dollars less but do yourself a favour and get this version.You can tell this version from the original in pictures by the camera side mount which is chrome in the new version and black in the original.

I have found the K&F Concept adapters well made and all mount easily without being too tight or loose. They make 2 different mounts, one cast metal, the other being chromed metal which are the ones I seek.

Adapted a vintage lens to my Sony A7r3. Wonks as expected for a great price!

A good quality adapter, recommended.

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.
