The EF-S 18-135mm f/3.5-5.6 IS USM from Canon is a versatile zoom lens optimised for both stills and video. Designed for APS-C format DSLRs, it features a 35mm equivalent focal length of 28.8-216mm to cover wide-angle to telephoto perspectives. With NANO USM technology, the lens features both a fast, stills-optimised ring-type USM Ultrasonic Motor and a smooth, silent video-optimised STM Stepping Motor. This dual-purpose AF motor also offers faster performance throughout the zoom range. An Image Stabiliser compensates for up to four stops of camera shake for sharper handheld shooting, and a Dynamic IS function works to reduce camera shake when recording video. This lens is also compatible with the optional PZ-E1 Power Zoom Adapter for more natural and silent zooming control when recording video. Optically it features one Ultra-Low Dispersion element and one precision moulded aspherical element to reduce chromatic aberrations throughout the zoom range and limit spherical aberrations and distortions, for increased clarity and sharpness. The exterior of the lens features a smooth satin finish, metal lens mount, dedicated focus mode and Image Stabiliser switches, and a black ring that clearly separates the zoom and focus rings for intuitive handling.
