Canon EF 28-135mm f/3.5-5.6 IS USM 

Description

This standard zoom lens features an Image Stabilizer and high zoom ratio. With the Image Stabilizer turned on, you can obtain sharp, natural-looking pictures in dim lighting without using flash or a tripod. It's very handy for places where flash is prohibited. The EF uses ring-type USM for swift, silent autofocus and full-time manual focus. Closest focusing distance is 20".
