The EF-S 60 mm f/2.8 USM Macro Lens from Canon is a true flat-field macro lens that can focus to full life-size magnification. It is optimized for digital SLRs with special coatings to minimize reflections and flare. Its angle of view with a floating optical system 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 multi-purpose lens that's equally at home shooting macro shots, portraits or available-light photos.
