Instructions
Thank you for purchasing a Canon product.
Safety Precautions
1. Do not look at the sun or a bright light source through the
lens or camera. Doing so could result in loss of vision. Looking
at the sun directly through the lens is especially hazardous.
2. Whether it is attached to the camera or not, do not leave the
lens under the sun without the lens cap attached. This is to
prevent the lens from concentrating the sun’s rays, which could
cause a fire.
2. Setting the Focus Mode
To shoot in autofocus (AF) mode, set the focus mode switch to AF ❹ .
To shoot in manual focus (MF) mode, set the focus mode switch
to MF, and focus by turning the focusing ring. The focusing ring
always works, regardless of the focus mode.

3. Infinity Compensation Mark
To compensate for shifting of the infinity focus point that res
from changes in temperature.
Handling Cautions
The infinity position at normal temperature is which th
vertical line of the L mark is aligned with the diator on
the distance scale ❻ .
If the lens is taken from a cold environment into a warm one,
condensation may develop on the lens surface and internal
parts. To prevent condensation in this case, first put the lens
into an airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it has warmed
gradually. Do the same when taking the lens from a warm
environment into a cold one.
●❻
• For accurate focusing in MF on sinfinitance, look
through the viewfinder while rcusining.
4. Infrared Index
The infrared index core focusing
monochrome infrareilm. Focus on MF, then
adjust the distance sng by moving g ring to the
corresponding infrarindex mark ❼ .
1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and
detaching the lens.
• Some EOS cameras nnot use rared film. See the instructions
for your EOS camer
• After detaching the lens, place the lens with the rear end up to
prevent the lens surface and contacts from getting scratched.
• If the contacts get soiled, scratched, or have fingerprints on them,
corrosion or faulty connections can result. The camera and lens
may not operate properly.
●❼
• The infrared index posn ised on a wavelength of 800 nm.
• Be sure to observe the manufacturer’s instructions when using
infrared film.
• Use a red filter also when you take the picture.
• If the contacts get soiled or have fingerprints on them, clean them
with a soft cloth.
• If you remove the lens, cover it with the dust cap. To attach it
properly, align the lens mount index and the index of the dust
cap, and turn clockwise. To remove it, reverse the order.
