Sigma APO Macro 180mm f/2.8 EX DG OS HSM Lens for Canon EF

Optimized for close-up work, this Canon EF-mount APO Macro 180mm f/2.8 EX DG OS HSM from Sigma is a unique medium telephoto lens, also characterized by a bright f/2.8 maximum aperture and apochromatic designation. The optical design employs three FLD elements to virtually eliminate chromatic aberrations and color fringing throughout the focusing range for improved clarity and color rendering. A Super Multi-Layer Coating has also been applied for greater contrast when working in strong lighting conditions.
