NOTE: This is an EF-S Series Lens and is compatible only with Digital SLR's that accept EF-S lenses like the EOS Digital Rebel , Digital Rebel XT, Digital Rebel XTi, EOS 20D, EOS 30D, EOS40D and similar. Do NOT Use With the EOS-5D, EOS-1D, EOS-1DS, EOS 1DS-Mark III Or Any Other EOS Camera. For photographers whose idea of a close-up is the full-frame flutter of a bumblebee's wings, the new EF-S 60mm f/2.8 Macro USM lens makes it happen. The EF-S 60mm f/2.8 Macro USM lens is a compact, internal focusing lens designed specifically for the EOS Digital Rebel XT SLR camera as well as the prosumer EOS 20D and entry-level EOS Digital Rebel SLR cameras. The new lens focuses from infinity down to 1:1 (lifesize) at a generous working distance of approximately four inches from the subject. What's more, because it is an internal focusing lens, the physical size of the new lens remains constant, ensuring that it will never inadvertently invade a subject's space. This is a particular advantage in macro nature shooting with live subjects when sudden lens movement such as a forward focus adjustment with a conventional macro can cast an unwanted shadow on the subject or send more wary species scampering for cover. Optimized for the large, APS-C size CMOS imaging sensor used by the two Digital Rebel cameras and the EOS 20D SLR, the EF-S 60mm f/2.8 Macro USM lens takes full advantage of the short back-focus and small image circle that characterize EF-S type lenses. The lens uses a 3-group floating inner focus system in which group one is fixed while groups two and three move on their own separate tracks. The process provides enhanced correction for any aberrations that may arise during focusing as well as a flat field that optimizes the lens's center-to-corner performance with tack-sharp image quality over the entire shooting area. This is coupled with a working distance of 90mm from the front of the lens to the subject during 1:1 macr... ...Read more
