EF400mm f/2.8L IS III USM

Lightweight 400mm large aperture professional lens with 5-stop image stabilization

Weighing significantly less (1,010g lighter) than its predecessor, the EF400mm f/2.8L IS III USM boasts improved mobility and portability, making it an excellent addition to a professional photographer’s kit especially for avid sports, bird and wildlife photographers. The use of ASC (Air Sphere Coating) provides images with high apparent resolution and contrast, and the improved 5-stop in-lens image stabilization (IS) helps to capture even sharper shots. In addition to the L-lens staple dust-proof, drip-proof structure and fluorine coating, the lens features a new heat shield coating that helps prevent the lens from overheating when shooting in the hot sun.

The high image quality you would expect from a flagship lens

The use of 2 fluorite and 1 Super UD lens elements correct chromatic aberration, removing one of the last hindrances to ideal image quality on a super telephoto lens and achieving stunning visual resolution and overall contrast. The EF400mm f/2.8L IS III USM also newly features Canon’s own Air Sphere Coating (ASC) technology, which incorporates air with a lower refractive index than optical glass into the coating, forming an ultra-low refractive layer that suppresses lens flare and ghosting.

Significantly reduced weight, professional-friendly operability

The lens achieves stunningly sharp, high-contrast images amid a body that, at 2,840g, weighs 25% lighter than its predecessor. Built to ensure durability and convenience even when shooting for long hours outdoors, it newly features a heat-shield coating to prevent overheating under the hot sun, in addition to fluorine coating on the lens surface to prevent dirt and stains from sticking and a dust-proof, drip-proof structure. The controls have also been improved for enhanced operability, with the likes of a new manual focus speed switch and a customizable electronic focusing ring that offers 3 levels of manual focusing speed to match the amount of rotation by the focusing ring.

5-stop IS, 2.5m closest focusing distance

Image stabilization (IS) has been significantly improved to 5 stops, with 3 versatile IS modes available, including IS Mode 2 for panning, and IS Mode 3 for unpredictable movement—created in response to popular demand from sports photographers. This, together with the drastically lighter lens body, expands the range of scenes that you can shoot by hand. A reduction in closest focusing distance to 2.5m from 2.7m on the predecessor allows you to shoot closer to your subjects while retaining same high image quality.

An insight into the technological breakthrough of the lens development and how they are able to reduce the weight tremendously.
