The F-501 is one of only three cameras, the others being the F3-AF and the F4, which can autofocus with the two AF-NIKKOR lenses introduced for the F3-AF, the 80 mm 1:2.8 and the 200 mm 1:3.5. Unlike other AF-NIKKOR lenses use a focus motor in the lens, rather than a mechanical coupling from a motor in the camera. AF-I, AF-S and AF-P Nikkor lenses also use a focus motor in the lens, but are not compatible with the short-lived system introduced with the F3-AF.
