Sigma AF 50mm f/1.4 DG HSM Art for Sony E is suitable for portrait and reportage, including low light. The f/1.4 aperture enables very shallow depth of field. The lens uses TSC (Thermally Stable Composite) for improved durability while maintaining compact size. The optical design includes aspherical and SLD low-dispersion elements to reduce chromatic aberrations and other distortions, improving edge sharpness. New-type multi-layer coatings minimize internal reflections and flare for sharp, high-contrast images. A 9-blade rounded diaphragm provides smooth bokeh. HSM indicates a quiet ultrasonic autofocus drive. Included: Sigma AF 50mm f/1.4 DG HSM Art Sony E lens, front cap, rear cap, 77 mm protective filter, lens hood.
