The Canon EF24-105mm f/4L IS USM lens is a

with an Image Stabilizer, and covers a wide
range of focal lengths from wide angle to

Features

effect of a shutter speed three stops faster.*
2. Aspheric and super UD lens elements 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.
6. 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.
