Adjusting the Revolving Mount
You can loosen the orientation lock-knob on the tripod mount to allow it to rotate as needed to fit a
particular camera model for switching between vertical and horizontal positions.
The EF200mm f/2.8L II USM lens can be used with the A II (B) tripod mount ring, sold separately.
Detaching
Use the following procedures to remove and attach the tripod mount.
Turn the locking knob
counterclockwise until it
becomes loose (about 3 turns),
and pull the knob in the direction
of the arrow to release the collar. With the collar open,
remove the tripod mount. To install, while pulling the
locking knob, bring the collar
to the original position, and
tighten the locking knob
securely.
If the foot of the tripod mount overlaps the switch, loosen the orientation locking knob on the tripod mount to
move the foot.
