Description
Mixing long reach with a relatively compact and lightweight design, the EF 400mm f/5.6L USM from Canon is a super telephoto L-series prime well-suited for sports and wildlife photography. Its advanced optical design incorporates a pair of low dispersion glass elements to significantly reduce color fringing and chromatic aberrations in order to achieve a high degree of clarity, and a Super Spectra coating has also been applied to maintain contrast and color fidelity when working in difficult lighting conditions. Complementing the imaging attributes, this 400mm f/5.6 also features a ring-type USM to deliver quick and quiet autofocus performance along with full-time manual focus control. Additionally, a removable rotating tripod collar is included for stable use of the lens atop a tripod or monopod.
Telephoto prime 400mm f/5.6 lens is compatible with full-frame Canon EF-mount DSLRs as well as APS-C models where it will provide a 640mm equivalent focal length.
One Super Ultra-Low Dispersion element and one ultra-low dispersion element greatly reduces chromatic aberrations and color fringing for improved clarity and color accuracy.
Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
A ring-type Ultrasonic Motor (USM), along with a rear focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
Built-in lens hood prevents stray light from causing ghosting or flare and also protects the front element from accidental impacts or scratching.
As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
Removable rotating tripod collar is included and benefits working with the lens atop a tripod or monopod.
Compatible with optional EF 1.4X and EF 2X teleconverters.
