EF 100mm f/2.8 Macro USM

The Canon EF 100mm f/2.8 Macro USM is a fixed focal length macro lens designed for full-frame Canon EF-mount DSLRs that achieves true life-size 1:1 magnification with a 1-foot minimum focusing distance. The lens features optical technologies including one ultra-low dispersion element for reduced chromatic aberrations and Super Spectra coating to minimize flare and ghosting. A ring-type Ultrasonic Motor provides fast and quiet autofocus performance with full-time manual focus override, while the internal floating focusing system maintains consistent image quality throughout the focusing range.

Beyond macro work, this 100mm focal length serves well for portraiture and short telephoto applications, with a rounded eight-blade diaphragm that contributes to pleasing bokeh. The lens includes a focus range limiter that allows you to constrain autofocus to either 1-foot-to-infinity or 1.6-feet-to-infinity for faster focusing performance, and an optional rotating tripod collar is available for stabilized shooting positions.
