Actually, all MF Nikkors but the 21mm f4 (and non-reflex fisheyes) will
all fit and work fine on AF bodies (manual and aperture auto exposure
modes only, no AF, no aperture readout in finder, no matrix metering - big deal!) - with a $25 modification required on non-AI lenses (plus $5 shipping) by John White: whitejt3@aol.com 9313-662-1734.
He does a nice job.
Hope this helps.
