Canon EF 400mm f/4 DO IS USM Lens

Overview

Unconventional in design and loaded with features, the Canon EF 400 mm f/4 DO IS USM Lens is the perfect choice for professional photographers. It is constructed with 17 elements in 13 groups, and offers a diagonal viewing angle of 6°. This lens features a multi-layer diffractive optical lens technology, which rectifies chromatic aberrations and minimizes the lens size to a great extent to deliver outstanding telephoto image quality.

This lens is constructed from magnesium alloy, which makes it lightweight, durable, and resistant to moisture and dust.
