The Sigma 30mm f/1.4 DC HSM Art Lens is 35mm focal length equivalent is 45mm which places it in the category of standard focal length lenses. With its particularly fast maximum aperture of f/1.4, the lens will perform very well in low light situations and provides a shallow depth of field focus. With updated optical configurations (9 elements in 8 groups), as well as rounded aperture blades, the lens delivers sharp detail and nice background bokeh. Its minimum focus distance is 30 cm.
The lens’s optimized light distribution helps to minimize field curvature preventing a loss of image quality at the edges of photographs and its double-sided aspheric lens element minimizes spherical distortion. A rear focusing system combined with a newly developed autofocus algorithm and Hyper Sonic Motor provides smooth and accurate autofocus. Full-time manual focus is also supported. As part of Sigma's "Art" line of lenses, it is compatible with Sigma's new USB Dock, which enables firmware updates and focusing adjustments.
