Large maximum aperture Sigma has a strong reputation for producing high-performance lenses by incorporating the latest optical techniques. The f/1.4 DG HSM A achieves extraordinary expressive power with a maximum aperture of f/1.4. Your wide angle photography benefits from excellent brightness even in the poorest light conditions with optimum resolution even in the periphery. Hyper Sonic Motor The HSM (Hyper Sonic Motor) ensures fast & quiet autofocus with full-time manual override. The enhanced AF algorithm gives you smoother autofocus which can be overridden anytime by rotating the focus ring. This drives a floating inner focus system that effectively compensates for astigmatic & spherical aberration, designed to maintain high optical performance for all subject distances, including extreme close-up photos. Reduced flare & ghosting Super Multi-Layer Coating is used to reduce flare & ghosting. Combined with an optical design engineered to be resistant to strong incident light, the f/1.4 DG HSM A provides sharp, high contrast images even in backlit conditions. Blur Effect The aperture diaphragm effectively uses 9 rounded blades to create an attractive bokeh effect in the out of focus areas of the image. As a result, you can achieve beautifully expressive photos with artistic peripheral distortion. Easy to use The Sigma ` Art Series' lenses are constructed with rubber for the attachment part of the lens hood allowing for better usability. The f/1.4 DG HSM A also incorporates a brass made bayonet mount which ensures high accuracy & durability.
