Adapter EF-Mount lenses (manual) to M39 thread

Adapter manual Canon EF lens to M39 thread -Precision made lens adapter -No information transfer -Exposure metering by means of aperture priority mode or completely manual NOTE: This adapter ring can only be used on a bellows unit! On cameras with M39 thread, lenses can not be focused up to infinity! As with all other NOVOFLEX adapters, this is a purely mechanical adaptation. With original Canon EF lenses, aperture control isn't possible. The use of EF-Mount lenses with a mechanical aperture ring (Canon EF Cine lenses, Zeiss Compact Prime lenses, Samyang, etc.) is recommended. To use original Canon EF lenses on the bellows, the reversing adapter EOS-RETRO is available. In combination with a Canon EOS cameras, this can be connected to all NOVOFLEX universal bellows.
