4. Infinity Compensation Mark

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.

5. Infrared Index

The infrared index corrects the focus setting when using

monochrome infrared film. Focus on the subject

manually, then adjust the distance setting by moving the

focusing ring to the corresponding infrared index mark.

Some EOS cameras cannot use infrared film. See

the instructions for your EOS camera.

• The infrared index position is based on a

wavelength of 800 nm.

• The compensation amount differs depending on

the focal length. Use the indicated focal length

as a guide when setting the compensation

amount.

• Be sure to observe the manufacturer's

instructions when using infrared film.

• Use a red filter also when you take the picture.
