10. Using the Tripod Mount
(Sold separately)
Adjusting the Revolving Mount
This lens can be used with the D (B) tripod mount ring, sold separately.
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.
Detaching
Use the following procedures to remove and attach the tripod mount.
The tripod collar can be attached to or detached from the lens while the lens is attached to the camera.
Depending on the EOS camera model, if a battery pack or vertical grip is attached, the tripod mount may
bump into it. If that is the case, remove the battery pack/vertical grip or 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.
