Warranty Limited 24-Months   • Phase One M645 lenses will not fit this adapter, only older Mamiya M645 lenses will fit properly. • All lenses will focus at least to infinity, some may just focus a little past. So if your lens is not in focus when the focusing ring is set to the infinity mark, this is due to how Focal Flange Distance (FFD) works and how we must compensate for all lenses of its type made over the years with the differences in tolerance. Visually focusing using the viewfinder or camera screen is the best way to ensure proper focus, not the distance markings as they may not match up properly. • 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. • All pictures are for illustration purposes only. Actual product may vary slightly due to ongoing improvements in design.
