Canon EF 300mm

The EF 300mm f2.8L lens features completely redesigned optics to provide better image quality and significant weight reduction. Equipped with Canon's Image Stabilization and magnesium alloy for improved build quality, coupled with dust and waterproofing makes this ultra-high-performance lens fit for the digital age.

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 pre-set 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.

Image sharpness is enhanced with fluorite optics that deliver reduced chromatic aberration and SWC (SubWavelength structure Coating) reduces flare and ghosting. A circular aperture design helps to produce pleasing out of focus areas.

Dust and water sealing keeps the lens functioning even in less than ideal conditions and magnesium and titanium construction elements make it lighter than its predecessor. Fluorine coating on the front and rear lens surfaces allow dirt to be removed easily and an attachment slot is provided for a wire-type security lock. The EF 300mm f2.8L is compatible with Canon's EF1.4x III and EF2x III extenders and this lens include a lens hood, 52mm drop-in gelatin filter holder, a detachable tripod collar and a hard travel case.

FEATURES

High-performance super-telephoto lens
With a large aperture of f2.8, the EF 300mm f2.8L is a high-performance super-telephoto lens delivering exceptional image quality in a durable and lightweight design.

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.

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.

Canon EF 300mm

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.

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.
