The Canon EF 28-135mm f/3.5-5.6 IS USM is a standard zoom lens with a versatile zoom range allowing it to respond to a variety of shooting situations. Released in early 1998, it's Canon's first lens to feature Image Stabilizer that compensates for hand shake to deliver sharp, crisp images even in low light condition without the need of tripod or flash. Premium optical performance is achieved via lens construction of 16 elements in 12 groups. The Ultrasonic Motor provides fast and quiet AF operation, and enables full-time manual focus override for precise focus tweaking even in the AF mode. The inner focusing design means the front of the lens will not rotate during focusing, thus special filter effect like polarizer will not be affected. Additionally, this lens comes in a relatively compact design and low weight of 540g, making it an all-round zoom lens that can be carried around wherever your travels take you.

Ever experienced one of those days when some of your pictures, shot under available light conditions, were ruined by camera shake and caused a substantial loss of sharpness? Well, kiss goodbye to all those camera-shake pictures via a remedy in the form of the new Canon EF28-135mm f/3.5-5.6 IS (Image Stabilizer) USM zoom lens. The IS system reduces the possibility of blurred photographs caused by camera shake, enabling handheld photography in comparatively dim light without a flash or tripod.
Image StabilizerCanon Optical Image Stabilizer technology makes handheld photography more practical at slow shutter speeds, accommodating more low-light shooting situations than ever before. Canon Optical Image Stabilizer technology uses miniature sensors and a high-speed microcomputer built into the lens. The sensors analyze vibrations and apply correction via a special stabilizing lens group that shifts the image parallel to the focal plane. Motion blur is canceled, resulting in a sharper image.
Ultrasonic MotorThe Ultrasonic Motor delivers fast and quiet autofocus performance, which is particularly important to video recording using this lens.
Full-Time ManualThe full-time manual focusing enables the photographer to manually tweak focus without switching out of AF mode.
Inner FocusingAn inner focusing lens has the focusing lens group(s) in front of the diaphragm, which allow for compact optical systems that produce faster AF. And because the front of the lens does not rotate to focus, filter orientation remains stationary for unaffected effect.
