Sigma AF 50mm f/1.4 DG HSM Art lens for Canon is suitable for portrait and reportage shooting, including low-light conditions. The maximum f/1.4 aperture enables very shallow depth of field. The lens uses TSC (Thermally Stable Composite) material for a durable body while keeping compact dimensions. The optical design includes aspherical elements and SLD low-dispersion glass elements to significantly reduce chromatic aberrations and other optical distortions. These elements improve edge-to-edge sharpness. A new-type multi-layer coating minimizes internal reflections and flare for sharp, high-contrast images. A 9-blade rounded diaphragm produces smooth background blur, and the HSM designation indicates a quiet ultrasonic autofocus motor. Included: Sigma AF 50mm f/1.4 DG HSM for Canon lens, front cap, rear cap, 77 mm protective filter, hood, pouch.
