All chrome-mount-ring FD lenses and FD macro
lenses are set for manual diaphragm control as
follows:
Before mounting the lens, push the automatic aper-
ture lever at the rear of the lens to the right where it
automatically locks.
Mount the lens onto the accessory as usual. The
diaphragm will now open and close as the aperture
ring is rotated.
Some of these lenses have an additional lock lever. With
these lenses, the automatic aperture lever must be
pushed fully to the right and the lock lever pushed to
"L" to hold the automatic aperture lever in that
position.
When using a macrophoto coupler, the Macro Hood
must also be mounted onto the rear of the lens.
You may avoid setting the lens for manual diaphragm
control when using manual accessories or a macrophoto
coupler by attaching the Canon Macro Auto Ring and / or
Double Cable Release (optional accessories).
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.
