From the Manufacturer --------------------- This compact and lightweight EF 75-300mm telephoto zoom lens is ideal for shooting sports, portraits, and wildlife. The lens is distinguished by a newly developed micro ultra-sonic monitor (USM) that makes autofocusing quicker and quieter, along with an improved zoom mechanism that includes a silver ring on the front for a luxurious touch. The micro USM makes this version of the lens particularly suitable for applications that require a fast autofocus, such as sporting events or wildlife shoots. Best of all, the USM version shares many of the same features that makes the non-USM lens so popular, such as a compact size, a close focusing range, and accessory compatibility. As with all Canon lenses, this unit carries a one-year warranty. * Focal length: 75-300mm * Maximum aperture: 1:4.5-5.6 * Lens construction: 13 elements in 9 groups * Diagonal angle of view: 32 degrees (at 11 feet) to 8 degrees (at 15 feet) * Focus adjustment: Front group rotating extension system with USM * Closest focusing distance: 4.9 feet * Zoom system: Rotating type * Filter size: 58mm * Dimensions: 2.8 inches in diameter, 4.8 inches long * Weight: 16.8 ounces Compact and lightweight 4x telephoto zoom lens ideal for shooting sports, portraits, and wildlife.

It also sees whatís near and not whatís 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.
