Canon EF 70-200mm f/4L USM

Buy it from:

Canon makes four versions of the 70-200mm L lens. Two versions have a max aperture of f2.8, and two have a max aperture of f4. Two have IS, and two do not.

This is the least expensive of the four with a max aperture of f4 (and no IS).

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.
