Thank you for purchasing a Canon product.

single focus lenses that provide high image quality.

Safety Precautions
●
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.
●
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.
Handling Cautions
●
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.
●
Do not leave the lens in excessive heat such as in a car in direct sunlight.
High temperatures can cause the lens to malfunction.

Supplementary notes on using the lens and taking pictures.
1. Mounting and Detaching the Lens
See your camera’s instructions for details on mounting and detaching the
lens.
●
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.
●
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

The infinity position at normal temperature is the point at which the vertical line of
the distance scale L mark is aligned with the distance index
