New Sigma APO 300-800mm F5.6 EX DG HSM IF Lens for Canon (1 Year Warranty)

The Canon EF-mount APO 300-800mm f/5.6 EX DG HSM from Sigma is a sophisticated zoom characterized by its advanced optics and constant f/5.6 maximum aperture. Designated an apochromat, this lens uses a pair of extra-low dispersion elements to effectively eliminate color fringing and chromatic aberrations for high clarity and color accuracy throughout the zoom range. A multi-layer coating has also been applied to lens elements to control flare and ghosting for improved contrast and clarity.
