Lens Mount: Deckel-Bayonett (Deckel Bayonet, DKL) Mount SLR Lens Body Mount: Canon EOS M (EF-M) Mount Mirrorless Camera Body Manufacturer: Fotodiox Inc. Warranty: 24 Months Note: • Some lenses may not open to the full max aperture such as the Schneider-Kreuznach Retina Xenon 50mm f/1.9 & Voigtlander 50mm f/2 Septon lenses due to the aperture travel restriction limitations of the adapter. More information can be found at the Fotodiox Solutions Knowledgebase here. • This is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. • Some cameras need to be set a certain way to work with our adapters or you may get a message such as 'Error Lens Not Attached - Check lens'. Please check the support articles on the Fotodiox Knowledge Base for possible solutions on a variety of camera brands. • 'Focus-By-Wire' lenses (such as Canon's STM or Nikons AF-P) requires power to engage the manual focus rings on the lens, since manual lens mount adapters do not power the lens, those lenses will not be able to focus. • Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. • If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position, which depending on the lens is either stopped down to its largest f-stop or opened up to its smallest f-stop. • To determine what the new 'Crop Factor' or 'Equivalent Focal Length' of the lens when used on your camera will be, please check the Fotodiox Knowledge Base article.
