Description

The Canon EF 400mm F2.8L II USM is one of Canon's legendary professional super-telephoto lenses, designed for demanding sports, wildlife, and photojournalism applications. Renowned for its exceptional sharpness, fast autofocus performance, and outstanding low-light capability, it has long been a staple lens on the sidelines of major sporting events and in the hands of professional wildlife photographers.

Its large F2.8 aperture provides excellent subject isolation and strong performance in challenging lighting conditions, while Canon's L-series construction ensures durability and reliability for professional use. The ring-type USM autofocus system delivers fast and precise focusing, making it ideal for tracking fast-moving subjects.

When paired with the Canon Extender EF 2X, the lens becomes an 800mm F5.6 super-telephoto setup, dramatically extending reach for distant wildlife, bird photography, motorsports, and other long-range applications. Even with the teleconverter attached, the combination maintains excellent image quality and remains a highly capable solution for photographers who require extreme telephoto performance.
