The EOSM/CAN allows mounting Canon FD-type lenses to an EOS M camera body.
Exposure metering can be Aperture Priority or Manually. No information is transferred between the lens and camera, so focus is manual.
Precise compensation of the flange difference of the two mounts allows lenses to be manually focused up to infinity
Lenses w/o aperture control ring can be manually stopped down with this adapter - no specific aperture value can be selected
