180mm f/2.8 APO EX DG OS HSM
Macro lens for Canon
The Sigma 180mm f/2.8 APO Macro EX DG OS HSM Lens for Canon EF mount is a high-speed macro lens with a magnification ratio of 1:1 designed for use with full-frame and APS-C DSLRs.
Optically 3 FLD glass elements control colour aberrations, while a floating inner focusing system works to reduce other aberrations such as field curvature and distortion. A Super Multi-Layer coating helps to eliminate ghosting and flare. The rounded 9 blade diaphragm produces pleasing bokeh in out of focus areas.
The integrated OS (Optical Stabilizer) system makes it possible to use this lens handheld with shutter speeds up to 4 stops lower than usual. A HSM (Hyper Sonic Motor) is also incorporated into the design, ensuring fast and quiet auto focusing and manual focus capabilities.
