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

Spanning a versatile range of long focal lengths, the EF 100-400mm f/4.5-5.6L IS USM Lens is a telephoto zoom and member of Canon's elite L-series of optics. One fluorite element and one Super UD element are featured, along with four aspherical elements, to produce well-corrected imagery without chromatic or spherical aberrations in order to realize a high degree of sharpness, clarity, and color accuracy. A floating elements system is also used to maintain image quality throughout both the focusing and zoom ranges. Complementing the imaging attributes, this 100-400mm also features an Image Stabilizer to minimize the appearance of camera shake by two stops for sharper handheld shooting. The ring-type USM is employed, too, to deliver quick and quiet autofocus performance along with full-time manual focus control. Additionally, a removable rotating tripod collar is included for stable use of the lens atop a tripod or monopod.
