The LensCoat Lens Cover for Canon EF 400mm f/4 DO IS II USM Lens is a dedicated neoprene lens protector designed to help shield the telephoto lens barrel from bumps, scratches, moisture, and everyday field wear. Its 100% closed-cell neoprene construction also provides thermal insulation during outdoor photography.

Clear UV-PVC windows maintain access to autofocus, Image Stabilizer controls, and the distance scale. The cover is easy to install and remove without residue and helps break up the lens profile. It is suited to wildlife, nature, sports, and photojournalism photography.
