Thank you for purchasing a Canon USM lens.
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.
