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.
