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.

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.
