Good quality, no documentation
Fit and finish is excellent. Works perfectly with Sony A7 and Canon FD and Sigma FD lenses. Problem with a Tamron FD lens though - didn't fit.One star off for no documentation on the "Lock - Open" ring. After some experimentation I figured it out. Turn so that "Open" is at the top, install the FD lens, and you can stop down the aperture manually in real - time. Turn to "Lock" and you will force open the aperture wide open.I'm not a good enough photographer to know why you'd want to "Lock" it, the viewfinder on the A7 meters quite well when you manually stop down.
