Can anyone explain this a bit better for me?
One adaptor per camera body in use with a screw lens is required. Whilst it's recommended to mount the adaptor to the screw lens then mount the assembly on the K body when removing the lens you simply unscrew it as the screw adaptor becomes locked into the mount and has to be released. The normal lens release button does not work with the adaptor. If you wished to fix a screw adaptor on each of your screw lenses you'd need to remove the adaptor locking flange and fabricate a locking pin hole on each lens assembly that mimics those found on a regular K mount lens. It sounds easier than it is because a lot of the screw mount lenses don't seat flat on the mount so a piece needs to be added. More trouble than it's worth in the end. I find using anything but A compatible lenses on my *ist D a PITA.
