Spanning a flexible range of telephoto focal lengths, the EF 70-300mm f/4-5.6L IS USM is a Canon L-series lens characterized by its relatively compact size and versatility. Two ultra-low dispersion elements are used to greatly reduce colour fringing and chromatic aberrations throughout the zoom range for high clarity and colour accuracy, and a Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast. Also, a floating elements mechanism is employed to maintain consistent image quality throughout the focusing range for notable sharpness from 3.9' to infinity.
High performance telephoto zoom lens With a focal length range of 70-300mm, the EF 70-300mm f4-5.6L IS USM is a compact and versatile telephoto zoom lens delivering exceptional image quality. Ideal for wildlife and sports photographers, as well as photo journalism and portraiture.
L-series quality The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are highly resistant to dust and moisture.
4-stop Image Stabilizer A 4-stop optical Image Stabilizer – specially designed for the lens’ specific focal length range – works to counteract image blur, which can occur during handheld shooting, or at slow shutter speeds. Automatic panning detection ensures effective performance when tracking moving subjects and, as the IS system is based in the lens, results are visible through the viewfinder during framing.
Two UD elements Chromatic aberration is virtually eliminated by the inclusion of two UD lenses, ensuring optimum image quality and sharpness.
Creative background blur An 8 blade circular aperture on the EF 70-300mm f4-5.6L IS USM creates beautiful background blur, making your subject stand out with dramatic effect.
Fast, quiet auto focus A ring USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive extremely rapid auto focus with near-silent operation. A high-speed CPU and optimised AF algorithms contribute further to AF speed. Good holding torque stops the focusing lens group without overshoot. Full time electronic manual focus override is available without having to switch out of AF mode.
