The Canon EF-S 18-135mm f/3.5 5.6 IS STM standard zoom lens is designed to exceed expectations and ideal for video and still images alike. This lens marks a normal for EF-S lenses. It features a refined Image Stabilization system that delivers as much as four equivalent stops of shake correction all over the zoom range and offers a maximum magnification of 0.28x on the telephoto end, even as remaining even more compact in size. This EF-S lens supports the Canon EOS Rise up T4i DSLR’s Movie Servo AF feature for smooth and quiet continuous AF throughout movie shooting by utilizing a six-group zoom system and the adoption of a stepping motor and focal point mechanism. High-speed autofocus is achieved thanks to an Inner focusing system, high-speed CPU, and optimized AF set of rules. This lens also features a Dynamic IS (Movie Shooting Mode only) that uses a wide image stabilization correction range to lend a hand ensure steady video even as shooting when walking.
