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).
