The Canon EF 100-400mm f/4.5-5.6L IS II USM Lens A long-reaching telephoto zoom characterized by a sophisticated optical design and advanced image stabilization technologies, the Canon 9524B002 EF 100-400mm f/4.5-5.6L IS II USM Lens is part of the esteemed L-series developed for full-frame EOS DSLRs. One fluorite element and one Super UD element have been incorporated into the lens' construction, and both help to reduce aberrations and distortions throughout the zoom range in order to deliver notable clarity, image sharpness, and faithful color reproduction.
An Air Sphere Coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery. Benefitting the optical components of the lens, a four-stop effective Optical Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different styles of shooting. Furthermore, a redeveloped rotation-type zoom ring pairs with an internal focusing mechanism, and an Ultrasonic Motor, to deliver quick and intuitive handling to benefit handheld shooting. Positioned as a versatile option for sports and wildlife photographers, this lens' list of attributes make it a viable telephoto zoom for a variety of shooting applications.
The Canon EF 100-400mm f/4.5-5.6L IS II USM lens delivers a superb combination of cutting-edge performance, compact construction and brilliant resolving power that's great for sports and wildlife photography. The lens features one fluorite and one super UD element to help provide impressive contrast and resolution with reduced chromatic aberration across the entire zoom range. Canon's new Air Sphere Coating (ASC) helps significantly reduce backlit flaring and ghosting, while fluorine coatings on the front and rear lens surfaces help lessen smears and fingerprints. A 9-blade circular aperture renders beautiful, soft backgrounds, and a 3 mode (standard, panning and exposure only) Optical Image Stabilizer provides up to 4 steps of image correction. The new inner focusing AF system helps ensure fast and accurate focus down to 3.2 ft. with a .31x maximum magnification. Usability enhancements include a rotation-type zoom ring with adjustable zoom torque for more precise, customizable zoom performance, a redesigned tripod mount that can be attached and detached without removing the lens from the camera, and an all-new lens hood with a side window that makes it simple to adjust specialty filters-like polarizers-without the need to remove the hood. Ruggedly constructed with advanced dust and water sealing for durability in a range of environments, the EF 100-400mm f/4.5-5.6L IS II USM lens is a stellar performer with refined controls for a wide variety of situations.
