Weighing significantly less (1 010g lighter) than its predecessor, the EF400mm f/2.8L IS III USM boasts improved mobility and portability, making it an excellent addition to a professional photographer’s kit especially for avid sports, bird and wildlife photographers. The use of ASC (Air Sphere Coating) provides images with high apparent resolution and contrast, and the improved 5-stop in-lens image stabilization (IS) helps to capture even sharper shots. In addition to the L-lens staple dust-proof, drip-proof structure and fluorine coating, the lens features a new heat shield coating that helps prevent the lens from overheating when shooting in the hot sun.
