Camera Lens Parts: Alignment Index for Mounting. Yet, its price is reasonable. The lens adapter effectively serves to make up the difference in focal flange distance between the camera and lens—for example, a Nikon F lens to Sony E adapter makes up the difference of 28.5mm to provide the proper total 46.5mm of focal flange distance for a Nikon F-mount lens to achieve infinity focus.

The first two were (and some still are) used with manual-only lenses. there are two different styles of "f" mount lenses. Autofocusing was impossible, and light metering was problematic, too. It adds extra available features, such as a control ring on lenses for changing aperture or ISO. EF-mount cameras have 10 pins to accommodate all options. Full-frame mirrorless mounts are much shorter. Direct adaptation was not possible without corrective optics. first, the lens that was built for the konica slr camera model "f" - in 1960 only - which had an additional lever on the back, bottom side of the lens to connect with the meter on the camera.
