Product Highlights: 28.8-216mm (35mm Equivalent) 1 UD Element & 1 Aspherical Element NANO USM Autofocus System EF-S Mount Lens/APS-C Format Compatible with PZ-E1 Power Zoom Adapter Image Stabilizer and Dynamic IS A resourceful zoom optimized for both unmoving and video, the EF-S 18-135mm f/3.5-5.6 IS USM from Canon is a 28.8 to 216mm equivalent lens intended for APS-C-format DSLRs. Integrating NANO USM technology, this lens is illustrated by its combination of a motionless-optimized ring-type Ultrasonic Motor, fast and smooth, quiet video-optimized Stepping Motor for exceptional focusing performance in benefit multimedia image-making. This dual-purpose AF motor provides notably faster performance in the whole zoom range for further responsive shooting at all distances. Additionally, also helping photo & movie recording, an Image Stabilizer system compensates for up to 4 stops of camera shake for quicker handheld shooting, and a Dynamic IS function specially helps to diminish camera shake during video recording. The lens is also well-matched with the elective PZ-E1 Power Zoom Adapter for more natural and convenient zooming performance. Updated to match the increasing existence of video in a photographer’s workflow, this zoom is adaptable in regard to both focus handling and its wide-angle to telephoto achieve. In view to the optical design, 1 Ultra-Low Dispersion element is characterized, beside with one PMo (precision molded) aspherical element, to lessen chromatic aberrations in the whole zoom range as well as limited spherical aberrations and deformations, for better precision and sharpness. A typical zoom designed for APS-C-format Canon DSLRs, this 18 to 135mm lens gives a 28.8 to 216mm equivalent focal length range which covers large angle for telephoto perspectives. The optical design integrates 1 UD element and 1 aspherical element to reduce chromatic and spherical aberrations in entire the zoom range for better clarity. NANO USM system uses both a ring type USM & an STM method to understand quick & accurate focusing which is also smooth and almost silent to suit with both applications of photography and video. This focusing system also affords permanent manual focus control when working in the single-shot AF mode. An Image Stabilizer compensates for up to 4 stops of camera shake for sharper handheld shooting & also includes a Dynamic IS setting for clear video results. The external of the lens includes a smooth metal lens mount, satin finish, keen focus mode and Image Stabilizer switches, and a black ring which clearly divides the zoom & focus rings for innate handling and an aesthetic exterior. The not obligatory PZ-E1 Power Zoom Adapter could be used for smoother, more usual and silent zooming control while video recording.
