8.Infinity Compensation Mark
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 infrared index position is based on a
wav elength 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 when you take the picture.
9. Infrared Index
Some EOS cameras cannot use infrared film. See
the instructions for your EOS camera.
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.
F or accurate manual focusing on subjects at
infinity distance, look through the viewfinder while
rotating the focusing ring.

•Autofocusing is still enabled with Extender EF1.4X II attached.
• When an Extender is attached, the AF speed will become slower by design to retain proper
AF control.
•First attach the Extender to the lens, then attach the lens to the camera. Detach it from the
camera in the reverse order. If you attach the lens to the camera first, misoperation may
occur.
• With Extender EF2X II attached to the lens, only manual focus is possible. However, with the
EOS-1Ds Mark III, EOS-1Ds Mark ll, EOS-1Ds, EOS-1D Mark lll, EOS-1D Mark ll N, EOS-1D
Mark ll, EOS-1D, EOS-1V/HS, EOS-3 camera, autofocusing with the center focusing point is
possible.
• Only one Extender can be attached to the lens and camera.
• If you use an Extender on the lens mounted on a EOS A2/A2E/5, set the exposure
compensation to -1/2 stop for the EF1.4X II or -1 stop for the EF2X II.
