A thoroughly modern design that's optimized for select Canon EOS digital SLRs. Its angle of view is equivalent to a 96mm lens on a 35mm camera, with a floating optical system that can focus down to full life-size (1: 1) magnification. Inner focusing, driven by a silent and powerful ring-type USM, means the lens' overall length never changes during focus.
This lens is a wonderful multi-purpose lens that's equally at home shooting macro shots, portraits or available-light photos.
Compatibility note, this lens is designed to fit crop sensor (APS-C) cameras only, such as the Rebel, 30D, 40D, 60D, 7D, etc. It will not fit full frame or APS-H cameras like the 5D or 1-Series.
