Canon EF 70-200mm f/4L USM Telephoto Zoom Lens for Canon SLR Cameras International Version

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,.

Isolate the Interesting Part 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
