[1] The F601 featured an improved second-generation autofocus system, motor drive for automatic film advance, a built-in pop-up electronic flash, a top shutter speed of 1/2000 of a second, and a new "Matrix" evaluative multi-zone metering program.
It is compatible with a wide range of Nikon F-mount lenses, including both autofocus and manual focus types.
However, Nikon's older, non-AI modified lenses will not mount without modification.
Due to a firmware defect, G-type lenses without an aperture ring are compatible (in program and shutter priority modes) only if the aperture ring position sensor is manually actuated to its maximum position, therefore their use is not endorsed by Nikon.
