Canon EF 70-200mm f/4L USM Specifications
Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. This high-performance, L-series telephoto zoom lens is distinguished by such features as an f/4 maximum aperture, an inner focusing system, and a ring-type ultra-sonic monitor (USM). The last two features combine to deliver quick and quiet autofocusing–a priority for many amateur and professional photographers. In addition, photographers can attach and use a circular polarizing filter without difficulty because the front lens element does not rotate during focusing. Compatible with the same tripod collar (sold separately) used with the EF 300mm f/4L USM lens, the lens carries a one-year warranty.
