The Canon EF-S 18-135mm f/3.5-5.6 IS STM Lens is an all-purpose, versatile zoom lens that joins the new STM family of Canon lenses. The Canon 18-135mm uses STM (stepping-motor technology) to ensure quiet, smooth focus operation when capturing stills or shooting video.
Thanks to the built-in 4-stop Dynamic Image Stabiliser (IS) the EF-S 18-135mm lens allows you to shoot sharp images handheld and shake-free movies. The Canon EF-S 18-135mm f3.5-5.6 IS STM Lens is a great, all-around lens suitable for a wide range of subjects and provides the user with a beautiful background blur. In combination with the technology above, this lens also includes ultra-low dispersion (UD) lenses, aspherical lens elements and lens coatings to ensure ghosting and flare is kept to a minimum throughout the entire zoom range.
Canon's STM lenses
Canon's new line of STM (stepping motor) lenses are specifically designed for shooting video with the camera's Movie Servo AF mode. The first STM lens was released along with the Canon EOS 650D and has been designed to work with the 650D's AF so that they're fast, accurate and silent. The result is a movie that sounds professional without the sound of the noisy AF motor in the background. A compact 18-135mm lens for still photography and EOS Movies. Equivalent to a 29-216mm lens on a full-frame DSLR. Movie Servo AF uses STM stepping-motor technology for smooth quiet focusing when shooting video with compatible cameras. Capture shake-free movies with a four-stop Dynamic Image Stabilizer, which stabilises the camera even when walking. Autofocus quickly and accurately, even on fast-moving subjects. Shoot pin-sharp images with a four-stop Image Stabilizer. Great image quality throughout the zoom range from UD and aspherical lens elements and Super Spectra coatings. Get close to your subjects with a minimum focusing distance of 0.39m. SPECIFICATIONS
