With a large aperture of f/2.8, the EF 300mm f/2.8L IS II USM is a high performance super-telephoto lens that delivers exceptional image quality in in a robust lightweight construction. . Using the three mode Optical Image Stabilization allows you to shoot at shutter speeds 4 stops slower, and the advanced third IS mode activates only when the shutter button is fully pressed, so you can pan with fast-moving subjects without the IS function interfering with composition and framing.
An ultrasonic autofocus motor (USM) enables smooth, fast and quiet autofocus and a Power Focus mode allows smooth focus change which is especially important while shooting video. A focus preset function allows you to store focusing positions and return to them in an instant when needed. An AF stop button will pause autofocus with just a touch and manual focus override allows precise manual focus even in AF mode.
High performance super-telephoto lens With a large aperture of f/2.8, the EF 300mm f/2.8L IS II USM is a high performance super-telephoto lens delivering exceptional image quality in a durable and lightweight design.
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.
Enhanced image quality with SWC coating Designed for use in digital photography, Canon’s patented Subwavelength structure coating helps minimise the ghosting and flare caused by internal reflections. By eliminating the cause, the coating reduces reflections and helps to deliver crisp, clear images.
3 IS Modes Ideally suited for all types of action photography especially those disciplines that require the utilization of panning, the new IS mode 3 only activates the image stabilizer element during exposure.
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 to fast AF performance. Full time electronic manual focus override is available without having to switch out of AF mode.
