Important I - Nikon FM2 Instruction Manual

IMPORTANT!
50
The Nikon FM2 is an AI-type (Automatic Maximum Aperture Indexing) camera
which performs full-aperture metering with AI -type lenses. The aperture rings of
these lenses are fitted with meter coupling ridges (see illustration). Almost all lenses
now manufactured by Nikon are the AI type. However, please confirm whether or
not your lens is AI before using it with the FM2.
Although almost all Nikkor lenses that have the Nikon F bayonet mount, as well as
the Nikon Series E lenses, can be mounted on the FM2, the FM2 cannot be used
with Nikkor lenses that have not yet been modified to offer the AI facility and with a
few special-purpose lenses because the FM2's meter coupling ridge is fixed , and
the FM2 does not have a mirror lock-up mechanism. For particulars, refer to the
table below.
