Canon 70-300 IS USM Lens Overview

The Canon 70-300 IS USM Lens should appeal to serious amateur nature and sports photographers, incorporating a 3-stop image stabilizer, superb auto focus and fantastic image quality.

Shutter speeds of up to three stops slower than otherwise possible is achieved with Canon's latest 3-stop image stabilizer and image blur is reduced significantly, creating outstanding hand held photography results. Options in low-light conditions are very much extended by shooting at a shutter speed of 1/60 per second with the Canon 70-300 IS USM Lens, as opposed to shooting a 300mm handheld at 1/500 per second. Unwanted vibrations are picked up by gyro sensors. The Canon 70-300 IS USM Lens provides 2-mode image stabilizer for shooting immobile objects. Mode 1 stabilizes the object along the horizontal and vertical axes. Mode 2 turns off correction in the panned direction and prevents the effect of dragging the object back through the frame when following a moving object. The image stabilizer switches off automatically when the camera is mounted on a tripod.

The micro USM motor in the Canon 70-300 IS USM Lens drives super responsive auto focus with unrivaled speed and virtually silent operation. The instant it arrives at the correct focus point the lens stops with precision and accuracy. The Canon 70-300 IS USM Lens has a big increase of AF speed compared to that of its predecessor. At the wide-angle setting the zoom is locked by a zoom ring locking mechanism, preventing possible damage by carrying and storing the lens in its most compact position. The lens allows for increased light absorption and reflections off the lens element surfaces are reduced to deliver crisp, undistorted images with natural color balance.
