Innity Compensation
Mark
For accurate focusing in MF on subjects at innity
distance, look through the viewnder or at the
camera’s LCD display while rotating the focusing
ring.
To compensate for shifting of the innity focus
point that results from changes in temperature,
there is a margin at the innity (∞) position.
The innity position at normal temperature is the
point at which the vertical line of the distance
scale L mark is aligned with the distance index.

8. 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.
