Features
1. The Image Stabilizer gives the equivalent
effect of a shutter speed three stops faster*.
2. Aspheric lens element for excellent imaging
performance.
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.
* Based on [1/(focal length x 1.6)] second. Generally,
it requires a shutter speed [1/focal length] second or
faster to prevent camera shake (in 35mm format.
With an EF-S lens, it would be [1/(focal length x
1.6)] second).
