<b>Ultra-high-performance L-series super-telephoto lens, featuring a 4 stop Image Stabilizer with 3 modes. The EF 400mm f/2.8L IS II USM delivers outstanding image quality in a robust design ideal for sports and wildlife photography.</b>
With a large aperture of f/2.8, the EF 400mm f/2.8L IS II USM is an ultra-high-performance super-telephoto lens delivering exceptional image quality in a durable design using magnesium alloy and titanium to reduce weight.
<b>L-series quality</b>
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.
<b>4-stop Image Stabilizer</b>
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.
<b>3 IS Modes</b>
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.
<b>Enhanced image quality with SWC coating</b>
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.
