USED Canon EF 28-135mm f3.5-5.6 IS USM Lens

A compact, lightweight standard zoom lens with an Image Stabiliser and high zoom ratio. With the Image Stabiliser turned on, you can obtain sharp, natural looking pictures in dim lighting without using flash or a tripod - Very handy for places where flash is prohibited! Uses ring-type USM for swift, silent autofocus and full-time manual focus. 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. The IS system is composed of a pair of gyro sensors to detect vertical and horizontal motion and a microprocessor that compensates for it by shifting special lens elements in parallel with the perceived movement. At the wideangle end of the zoom range, the equivalent shutter speed gain is approximately 1.5 stops while at the telephoto end, it is approximately 2 stops.
