Canon FD Lenses to Sony E Mount Camera Copper Adapter
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.
