To get a feel for old screw lenses, I purchased an older 200mm Telyt f/4 screw mount lens. Along with it, I purchased the bayonet to screw adapter (or is that screw to bayonet?), model 16466M.
So far, I have not been able to get the adaptor to mount on the camera. Is it user error, or was I mistaken that 16466M is not compatible with the M8?
