The Canon EF 70-200mm f/4L USM is a high performance L-series telephoto zoom lens offering excellent image quality. The Canon EF 70-200 features non-rotating front element during focus, making it possible to use circular polarizing filters without additional adjustment.
Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm f/4L USM 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.
The Canon EF 70-200 is a truly professional L-series telephoto zoom lens, with reduced size and weight for applications where portability is important. Superb optically, the Canon EF 70-200mm f/4L USM lens combines a Fluorite element with two UD-glass elements for outstanding contrast and performance. Its ring-type USM is fast, silent, and permits full-time minimum focus, as well as the closest MF of any of the L-series 70-200 designs. The Canon EF 70-200 lens is also compatible with EF Extenders 1.4x II and 2x II, and accepts an optional accessory tripod collar.
The eye tends to see the whole rather than the individual parts. It also sees whats near and not whats far. By bringing attention to those things missed by the eye, you can create many interesting pictures. It could be the grimace of an athlete, the grill of a classic car, or a girl against a blurred background. Telephoto lenses can also compress images to give dramatic effects. You are limited only by your imagination.
