Featuring the latest 3-stop Image Stabilizer for outstanding camera shake reduction, the EF 70-300mm f4-5.6 IS USM zoom lens also features super responsive autofocus. Replacing the popular EF 75-300mm f4-5.6 IS USM, the world’s first interchangeable lens with Image Stabilizer (IS), the lens is expected to appeal to serious amateur nature and sports photographers looking to achieve outstanding results while shooting hand held.

Image Stabilizer
IS dramatically reduces image blur caused by camera shake. The EF 70-300mm f4-5.6 IS USM features Canon’s latest 3-stop IS, a one-stop improvement over its predecessor. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. The EF 70-300mm f4-5.6 IS USM provides 2-mode IS for shooting immobile subjects.

Superb autofocus
The micro USM motor found in the EF 70-300mm f4-5.6 IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation.

Pleasing defocused background
The EF 70-300mm f4-5.6 IS USM employs an electro-magnetic diaphragm (EMD) with a circular aperture.

Image quality
By optimizing Super Spectra lens coatings and lens element shaping, Canon’s engineers have been effective in suppressing flare and ghosting–more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural color balance.

Focal length translates to 112-480mm equivalent in 35mm film format when fitted to EOS 20D and EOS 350D cameras.

When used in conjunction with Canon’s range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering.

Accessories for the EF 70-300mm f4-5.6 IS USM include the lens hood ET-65B and the lens pouch LP1222.
