6. Infinity Compensation Mark

Distance index
Infinity compensation mark

7. Infrared 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 focusing in MF on subjects at infinity distance, look through the
viewfinder while rotating the focusing ring.
The infrared index corrects the focus setting when using monochrome infrared
film.
Focus on the subject in MF, 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.
• Be sure to observe the manufacturer's instructions when using infrared film.
• Use a red filter also when you take the picture.
