The Sigma 35mm f1.4 DG HSM A Standard Prime Lens is part of the high performance 'Art Series', featuring superb optics, for professional and serious amateur photographers. Advanced optical design Designed with sophisticated optical performance, the DG HSM A combines complex features, with easy handling. Its 13 element, 11 group construction includes Super Low Dispersion SLD glass and 'F' Low Dispersion FLD glass elements, which have performance equal to fluorite. This helps minimize and correct both the chromatic aberration of magnification and axial chromatic aberration to achieve ultra high quality images. Large maximum aperture Sigma has a strong reputation for producing high performance lenses by incorporating the latest optical techniques. The f1.4 DG HSM A achieves extraordinary expressive power with a maximum aperture of f1.4. Your wide angle photography benefits from excellent brightness even in the poorest light conditions with optimum resolution even in the periphery. HyperSonic Motor The HSM HyperSonic Motor ensures fast and 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 and spherical aberration, designed to maintain high optical performance for all subject distances, including extreme close up photos. Reduced flare and ghosting Super Multi Layer Coating is used to reduce flare and ghosting. Combined with an optical design engineered to be resistant to strong incident light, the f1.4 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 f1.4 DG HSM A also incorporates a brass made bayonet mount which ensures high accuracy and durability. With excellent image quality, professional grade optics and flawless operation, the Sigma 35mm f1.4 DG HSM A Standard Prime Lens for Canon delivers on performance at a competitive price.
