 Canon EF 75-300mm f/4-5.6 III USM Telephoto Zoom Lens for Canon SLR Cameras Specifications 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.
