>Does the F2 use the AI bayonet or the older prong-coupling IC mount?

All Nikons can use AI/AIS lenses - the only limitation is that newer
bodies generally must have AI (or AI'd) lenses for the lenses to fit
on the body. For meter coupling (non-meter coupling lenses can always
be used in stop-down meter mode, if they will fit on the body), F2's
with the "A" in the model (F2A, F2AS) use the AI ridge at the rear of
the lens for coupling, the others use the prong (which also is on
AI and most AIS lenses...).
Hope This Helps
