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.
