EF 100-400mm f/4.5-5.6 L IS USM

The Canon EF 100-400mm f/4.5-5.6L IS USM is a professional-grade telephoto zoom lens designed for Canon EOS DSLRs, offering a versatile focal range that extends to 640mm equivalent on APS-C sensor bodies. The lens incorporates advanced optical elements including one fluorite element, one Super UD element, and four aspherical elements, along with a floating elements system to deliver sharp, well-corrected imagery with minimal chromatic and spherical aberrations throughout the zoom range. An optical image stabilizer reduces camera shake by up to two stops, enabling sharper handheld photography in low-light conditions, while the ring-type ultrasonic motor provides fast and quiet autofocus with full-time manual focus override.

The lens features a removable rotating tripod collar for stable support on a tripod or monopod, an adjustable zoom ring lock that secures the focal length, and an 8-blade diaphragm that produces pleasing background bokeh. Compatible with optional EF 1.4X and EF 2X teleconverters, this L-series optic is built for professional-quality telephoto and wildlife photography applications.
