Mounting And Removing Lenses - Nikon FR Instruction Manual

MOUNTING AND REMOVING LENSES
To mount a lens fitted with a meter coupling ridge, first
make sure that the camera's meter coupling lever is in
the normal position (i.e ., it protrudes from the camera's
lens mounting flange) . Position the lens in the flange so
that the mounting index on the lens is aligned with the
mounting index on the camera body . Then, twist the
lens counterclockwise until it clicks and locks into place.
The lens ' maximum aperture is automatically indexed to
the camera's meter as soon as it is mounted.

To mount a lens not fitted with a meter coupling ridge,
first make sure that the camera's meter coupling lever is
locked up out of the way by pushing the coupling lever
release and manually lifting the lever up. The mounting
procedure is the same as described previously. Remem-
ber that stop-down exposure measurement is required
for lenses of this type (see page 30).
To remove the lens from the camera body, push in the
lens release button while twisting the lens clockwise as
far as it will go. Lift the lens out when it comes loose.
Note: The Nikon Fisheye 6mm f/5.6 and OP 1 Omm f/5.6 cannot
be used with the Nikon FE, because the camera does not have a
provision for locking the mirror in the " up" position.
