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

❽

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

❾

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.
