The 18-135mm f/3.5-5.6 EF-S IS STM Lens from Canon is a wide angle zoom lens with an 18-135mm focal range that is equivalent to 29-216mm in the 35mm format. This wide set of focal lengths offers flexibility in shooting everything from expansive landscapes and cramped interiors to group shots, portraits and distant subjects. Optical Image Stabilization reduces the blurred effect of camera shake up to 4 stops and the new Dynamic Image Stabilization improves the look of video while tracking moving subjects or walking with your camera.
This EF-S lens is designed to match the APS-C sensor size and its STM designation (Stepping Motor) gives it a smooth and quiet autofocus that is ideal for shooting video with the Movie Servo AF feature found on select Canon DSLRs. Autofocus speed is achieved thanks to the lens' high speed CPU connection with the camera and its Inner Focusing System. Auto and manual focusing is possible, aspheric and UD lens elements provide quality imaging and a zoom lock ring prevents the lens from accidentally extending. Given its wide focal range, it is particularly compact and lightweight, which is also beneficial when shooting video.
Note: This lens is not compatible with full-frame cameras. The STM feature of this lens presently works only with the Canon EOS Rebel T4i & T5i.
