Canon 9524B002 EF 100-400mm f/4.5-5.6L IS II USM camera lens

Telephoto Zoom for Canon DSLRs

The Canon EF 100-400mm f/4.5-5.6L IS II USM is a professional L-series telephoto zoom lens built for full-frame Canon DSLRs and compatible with APS-C models. It covers a focal range of 100 to 400 mm with a variable aperture of f/4.5-5.6. Optical construction includes one fluorite and one Super UD element plus Air Sphere Coating to control aberrations and flare. A ring-type ultrasonic motor drives fast, quiet autofocus.

Mount and Filter Compatibility

Verify that your camera body uses the Canon EF mount before ordering. The lens accepts 77 mm front filters and measures 3.70 inches in diameter by 7.60 inches in length. It weighs 3.5 lbs, so confirm your tripod head and bag can support the mass. Minimum focus distance is 3.2 feet with a maximum magnification of 0.31x. The aperture stops down to f/38 for extended depth of field when needed.

Sports and Wildlife Specialists

This lens suits photographers who need long reach for sports, wildlife or aviation subjects and value optical stabilisation rated to four stops. The weather-sealed barrel and fluorine coating protect against dust and moisture in outdoor use. Buyers who want a wider angle of view than 24 degrees or a constant maximum aperture should look at other options. Videographers requiring smooth power zoom or internal focus breathing correction will need a different design.
