9. Infrared Index
● 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 lm.
● Use a red lter when you take the picture.
Some EOS cameras cannot use infrared lm. See
the instructions for your EOS camera.
The infrared index corrects the focus setting
when using monochrome infrared lm. Focus on
the subject manually, then adjust the distance
setting by moving the focusing ring to the
corresponding infrared index mark.
