EF70-200mm F2.8L IS USM

ENG-1

The Canon EF 70-200mm f/2.8L IS USM is a
high-performance, telephoto zoom lens
dedicated to Canon EOS cameras. It is equipped
with an Image Stabilizer to help preventing blurred
shots due to camera shake during slow shutter
speeds.
In the lens name, "IS" stands for Image
Stabilizer, and "USM" for Ultrasonic Motor.

a 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.

Features

1. The four UD elements help capture very sharp
and clear pictures with outstanding image
delineation.

2. The Image Stabilizer gives the equivalent
effect of a shutter speed three stops faster.

3. Ultrasonic motor (USM) for fast, quiet focusing.

4. Manual focusing enabled during AF
(autofocusing).

5. A truly round aperture hole results in a nicer
background blur.

6. Compatible with Extenders.

7. Sealed construction for higher resistance
against dust and moisture.

ENG-4

See your camera’s instructions for details on
mounting and detaching the lens.

• After detaching the lens, put it down with the
contacts upwards, to avoid damaging the
contacts or lens surface.

• If the contacts are dirty, scratched, or soiled with
fingerprints, etc., corrosion or a faulty
connection or operation may result.

•

Always attach the dust cap to the lens whenever it
is not mounted on the camera. To attach the dust
cap, align the mark on the dust cap with the mark
on the lens and turn the dust cap clockwise. To
remove the dust cap, turn it counterclockwise.

1. Mounting and Detaching the Lens

The lens mount has a rubber ring for enhanced
water- and dust-resistance. The rubber ring may
cause slight abrasions around the camera's lens
mount, but this will not cause any problems. If the
rubber ring becomes worn, it is replaceable by a
Canon Service Center at cost.
