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

The Canon EF 100-400mm f/4.5-5.6L IS II USM is a professional-grade telephoto zoom lens designed for Canon full-frame EOS DSLRs, offering an equivalent focal length of 160-640mm on APS-C sensor cameras. The lens incorporates advanced optical elements including one fluorite element and one Super UD element to minimize chromatic aberrations and deliver sharp, detailed images across the entire zoom range. A four-stop optical image stabilizer with three selectable modes—Standard, Panning, and During Exposure Only—effectively minimizes camera shake for handheld shooting and low-light situations.

The lens features a ring-type ultrasonic motor for fast and quiet autofocus operation with full-time manual focus override, complemented by a redeveloped rotation-type zoom ring with adjustable zoom tension for personalized control. A weather-resistant barrel with fluorine coatings on the front and rear elements protects against dust, moisture, and fingerprints, while the included ET-83D lens hood features a side window for rotating filter adjustment. Additional features include a removable tripod collar and a rounded nine-blade diaphragm that produces pleasing out-of-focus bokeh.
