Product Overview

This Canon EF 400mm F/4 DO IS USM Lens is a supert telephoto prime lens designed for Canon EOS 35mm SLR cameras but can also be used on Canon EOS DSLR cameras.

This is the first 400mm super telephoto lens for photography with the new multi-layered diffractive optical elements, or DO lens elements. It delivers unrivaled imaging performance while keeping size and weight down to the manageable levels. By combining DO lens elements with normal refraction elements, colour aberration is corrected to levels even higher than is possible with flourite elements. This lens also has the fastest autofocusing in the world*1. Equipped with an Image Stabilizing mechanism and a thoroughgoing dust-proof and drip-proof*2 construction, it can be used in even the harshest weather conditions. It also comes with an AF Stop function for outstanding operability and mobility. The green line on the lens barrel is a symbol of the innovative technologies used to design and produce Canon lenses, and is shared by the Canon FL_F 300mm f/5.6 which appeared in 1969, the first SLR lens in the world to use the flourite lens elements.
