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.
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.
The intermediate marker between 200 and 135
is 150 mm.
U Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
U For accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.
[il The infrared index position is based on a
wavelength of 800 nm.
Be sure to observe the manufacture's
instructions when using infrared film.
Use a red filter also when you take the picture.
