Mount

Tripod mount adapter Tripod mount ring B (B)
• When switching to vertical shooting, rotate the
camera so that the grip is at the top. Rotating
the camera in the opposite direction will have
the grip bump into the tripod mount.
• Before attaching or detaching the lens, set the
tripod mount back to its normal position
(horizontal shooting position). Otherwise, the
tripod mount may bump into the camera grip or
pentaprism and prevent the lens from being
attached to or detached from the camera.
• If the EOS camera has a built-in flash, the
pentaprism may prevent the tripod mount from
being rotated to the top of the lens.
Infinity compensation mark
Distance index
To compensate for shifting of the infinity focus
point that results from changes in temperature.
The infinity position at normal temperature is the
point at which the vertical line of the L mark is
aligned with the distance indicator on the
distance scale.
For accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.
