Features:

Wide Focal Range
With 74.2° to 11.3° angle-of-view, the Canon EF-S 18-135mm f/3.5-5.6 IS STM Lens offers excellent wide angle to telephoto focal lengths with Canon APS-C EOS Digital SLRs. In 35mm format its focal range is equivalent to 29-216mm.

Image Stabilization
Canon’s Optical Image Stabilization system reduces the effects of camera movement and allows you to shoot sharp images with a 4-stop advantage in low-light conditions.

Compact Design
Measuring less than 4″ in length and weighing about a pound, the lens boasts excellent portability without compromising optical quality.

High Speed Autofocus
An Inner Focusing system, optimized AF algorithm and high-speed CPU connections provide this lens with fast and accurate autofocus.

Ideal for Video
The stepping motor (STM) and focus mechanism and a new six-group zoom system offer quiet and smooth autofocus when used with the Movie Servo AF feature on select Canon DSLRs. This is ideal when shooting video so noise and jerky movements do not disrupt your action. The Dynamic Image Stabilization feature in Movie Shooting Mode reduces the effect of camera movement when shooting video while moving.
