The Canon EF28-300mm f/3.5-5.6L IS USM
lens is a powerful high-performance zoom
lens for EOS cameras equipped with an
Image Stabilizer, and covering a wide range
of focal lengths from wide angle to telephoto.
• "IS" stands for Image Stabilizer.
• "USM" stands for Ultrasonic Motor.
Features
1. The Image Stabilizer gives the equivalent
effect of a shutter speed three stops faster*.
The lens also has a second image stabilizer
mode that is optimized for following shots of
moving subjects.
2. Aspheric and UD lens elements for truly
exceptional imaging capability.
3. Ultrasonic motor (USM) for quick and quiet
autofocusing.
4. Manual focusing is available after the subject
comes into focus in autofocus mode (ONE
SHOT AF).
5. A truly round aperture hole results in a nicer
background blur.
6. Adjustable zoom ring touch lets you lock at
any focal length.
7. Tight seal structure ensures excellent dust-
proof and drip-proof performance.
* Based on [1/focal length] second. Generally, it requires
a shutter speed [1/focal length] second or faster to
prevent camera shake.
