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.
