● 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.
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.
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
