The Canon EF 100-400mm f/4.5-5.6L IS USM is a professional telephoto zoom lens built for photographers capturing wildlife, sports, and distant subjects. Its versatile 100 to 400mm focal range offers strong reach while maintaining framing flexibility, and on APS-C cameras it provides a 160-640mm equivalent field of view for extended coverage. The optical design incorporates a fluorite element, a Super UD element, and four aspherical elements to minimize chromatic and spherical aberrations, producing sharp images with accurate color and contrast across the frame. A floating elements system preserves clarity throughout the zoom and focusing ranges from 5.9 feet to infinity so subjects remain crisp at any distance. Optical image stabilization compensates for up to two shutter speed stops, improving handheld shooting and low-light performance, and a dedicated panning mode supports continuous tracking photography. The ring-type Ultrasonic Motor enables fast, quiet autofocus with full-time manual override for precise control during still or action shooting. An adjustable zoom ring allows tension adjustment and focal length locking for stable handling in the field. The included rotating tripod collar improves balance when mounted on tripods or monopods for long sessions. Compatible with optional 1.4x and 2x teleconverters and featuring an eight-blade diaphragm for smooth background blur, this durable L-series lens delivers dependable performance and flexibility for demanding telephoto photography applications in professional environments.
