Designed to exceed expectations and ideal for video and still images alike, the new EF-S 18-135mm f/3.5-5.6 IS STM marks a new standard for EF-S lenses. It features a refined Image Stabilization system that delivers up to four equivalent stops of shake correction throughout the zoom range; and offers a maximum magnification of 0.28x at the telephoto end, while remaining even more compact in size. This EF-S lens supports the Canon EOS Rebel T4i DSLR's Movie Servo AF feature for smooth and quiet continuous AF during movie shooting by utilizing a new six-group zoom system and the adoption of a stepping motor and focus mechanism. High-speed autofocus is achieved thanks to an Inner focusing system, high-speed CPU, and optimized AF algorithm. Appearing for the first time in a Canon lens is Dynamic IS (Movie Shooting Mode only) that uses a wide image stabilization correction range to help ensure steady video while shooting when walking.
