To clarify: both the AI *and* non-AI finders will fit and

meter all *reflex* Nikkors except the "G" series. With the

AI finder, the meter AI clip needs to be swung up with non-AI

lenses and stop-down metering used; with the non-AI finder,

the meter needs to be set for stop-down metering before the

lens is mounted - about equally "un-difficult" (and the meters/lenses

can be made so that all use stop-down metering, simplifying

things with mixed lenses and giving potentially more accurate

metering...).
