5. Infinity Compensation Mark
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 focusing in MF on subjects at infinity distance, look
through the viewfinder while rotating the focusing ring .
6. Hood
To attach the hood, align the hood’s attachment position mark
with the red dot on the front of the lens, then turn the hood in the
direction of the arrow until the lens’s red dot is aligned with the
hood’s stop position mark .
The hood can be reverse-mounted on the lens for storage.
• Part of the picture may be blocked if the hood is not attached
properly.
7. Filters (Sold Separately)
You can attach filters to the filter mounting thread on the front of
the lens.
• Use a polarizing Canon filter (77mm).
8. Switching the Focusing Distance Range (EF70-
200mm f/2.8L USM Only)
You can set the focusing distance range to 1.5 m/4.9 ft. to infinity or
3m/9.8 ft. to infinity .
• If you use AF from outside the specified focusing distance range,
the lens may stop focusing when it reaches the limit of the range.
This is not a malfunction. If this occurs, press the shutter button
halfway down again.
9. Extenders (Sold Separately: EF70-200mm f/2.8L USM
Only)
AF is possible with Extender EF1.4× II/EF2× II.
• The aperture F values and focal lengths when an extender is used
are as follows:
EF1.4× II: f/4, 98-280mm, EF2× II: f/5.6, 140-400mm
Attach the extender to the lens, and then attach the lens to the
camera. To remove it, reverse the order. Errors may occur if you
attach the extender to the camera first.
When you are using an extender, use the center focusing point for
AF. If you use AF with a different focusing point, a focusing error
may occur.
10. Using the Tripod Mount (EF70-200mm f/2.8L USM
Only)
By loosening the orientation locking knob on the tripod mount you
can rotate the camera to set the image for any vertical or horizontal
position.
