Compatibility
Like all Nikon SLRs, the F-501 accepts Nikon's F-mount lenses, but will only autofocus with lenses designated "AF." Likewise, fully automatic exposure will only work with Ai-S type lenses, including many autofocus lenses (G-type lenses are not supported by the F-501). In both cases, the camera will function with lenses without these abilities, but will not autofocus or may not have full auto exposure capabilities. AF lenses designated "D" add no functionality to the F-501, and "AF-S" and "VR" lenses will not perform their special functions if attached to an F-501.
Continuing Nikon's practice at time, the F-501 had interchangeable focusing screens, a feature that is now quite unusual. Three screens (types B, E and J) were available for the F-501.
Breaking from practice, though, Nikon removed the ISO-type cable release socket. Remote control functionality is still available, however, through the three-pin terminal on the camera's front with the Remote Cord MC-12 and the like. ISO cable releases can be accepted by the Terminal Release MR-3, which also doubles as a second shutter button.
