Fully compatible with all EOS cameras, the EF 24-85mm f/3.5-4.5 USM is particularly useful as a standard zoom lens for the EOS IX Advanced Photo System SLR, providing enhanced wide-angle capability for the smaller APS format.
Aimed to satisfy the most demanding professionals and advanced amateur photographers, its enhanced optical design has multiple moving lens groups and features that adjust and compensate for a variety of conditions. Ultrasonic Motor (USM) technology and an internal focusing system enable silent, high speed autofocusing. A wide rubberized focusing ring and manual focusing capabilities - even in Auto Focus mode - provide maximum flexibility and ease of use. Key optical features built into the system include a replica aspherical lens element that minimizes distortion and produces sharp, high resolution images, and a flare-cutting diaphragm that helps the lens maintain high contrast even in tough lighting conditions. So snap on the new Canon EF 24-85mm f/3.5-4.5 USM zoom lens to make sure your pictures are, well, picture perfect.
