Sigma APO 500mm f/4.5 EX DG HSM Lens for Canon EF

A truly long-reaching lens designed for Canon EF-mount cameras, the APO 500mm f/4.5 EX DG HSM from Sigma is a super telephoto characterized by its apochromatic optical design. Employing a pair of extra-low dispersion glass elements, chromatic aberrations and color fringing is virtually eliminated for notable clarity and color accuracy. A multi-layer coating has also been applied to realize greater contrast when working in backlit or difficult lighting conditions.
