An adaptable zoom optimized for both video and stills, the EF-S 18-135mm f/3.5-5.6 IS USM from Canon is a 28.8 to 216mm equal lens made for APS-C-format DSLRs. Integrating NANO USM technology, this lens is characterized by combination of a quick, stills-optimized ring-type Ultrasonic Motor & smooth, quiet video-optimized Stepping Motor for versatile focusing performance to benefit multimedia image-makers. This multi-purpose AF motor also provides remarkably faster performance all through the zoom range for more reactive shooting ranges from near to distant. Moreover, also aiding movie and photo recording, an Image Stabilizer system reimburses for up to 4 stops of camera tremble for sharper handheld shooting, and a Dynamic IS function particularly helps to decrease camera shake while recording video. The lens is also well-suited with the elective PZ-E1 Power Zoom Adapter for more controllable and natural zooming performance. Upgraded to suit the growing presence of video in a photographer's workflow, this zoom is resourceful in regard to both wide-angle as well as its focus handling to telephoto reach.
In view to the optical design, 1 Ultra-Low spreading element is featured, with 1 PMO (precision molded) aspherical element, to decrease chromatic aberrations during the zoom range as well as limit spherical aberrations & distortions, for increased clearness and brightness.
A normal zoom structured for APS-C-format Canon DSLRs, this 18 to 135mm lens offers a 28.8 to 216mm equivalent focal length range which covers broad-angle to telephoto perspectives. The optical design integrates 1 UD element & 1 aspherical element to reduce chromatic and spherical aberrations all through the zoom range for improved clarity. NANO USM system utilizes both a ring type USM and an STM mechanism to realize quick and accurate focusing that is also smooth and near-silent to suit both video and photography applications. This focusing system also gives full-time manual focus control while working in the one-shot AF mode.
