Surprisingly well built
I bought this to use Canon FD lenses with a Panasonic GH4 in a fully manual mode. (This is a simple adapter and does not provide any communication between lens and camera.) The adapter seems well built. It fits well on both camera and lens and the Lock/Open ring turns smoothly. (This ring controls the aperture, and should be set to Lock when attaching the adapter. In the Lock position, the lens's aperture ring will change the aperture. In Open position, the lens remains wide open.)
