Be
sure to reset the automatic aperture
lever to its normal position before using the
lens once more in direct contact with the
camera. In the case of a lens with
a
lock lever,
switch
it
back to the position of the white
dot.
Changing
the
Lens
Since
FD
lenses have signal pins and
levers which couple with the camera body,
special care must be taken not to damage
them. One basic precaution
is
to always put
the lens down facing down whenever you
must change lenses.
The following lenses can be mounted but
for technical reasons cannot be used with the
