From Sigma:
 
The Sigma Corporation is pleased to announce the new Sigma 30mm F1.4 DC HSM, the large-aperture APS-C standard lens.
 
“SIGMA 30mm F1.4 DC HSM”, the large-aperture standard lens with an angle of view equivalent to 45mm on a 35mm camera, is a superb go-to lens for artistic photography on an APS-C format digital SLR. Offering the bright f/1.4 aperture and an angle of view extremely close to that of human vision, this lens is ideal for many different types of photographic expression.
 
Featuring an advanced design and the latest manufacturing technologies, SIGMA 30mm F1.4 DC HSM, the large-aperture APS-C format standard lens delivers the highest level of image quality worthy of the Art line. The photographer can leverage the shallow depth of field that creates beautiful bokeh for snap shots, portraits, landscapes, and many different styles of photography.
 
Sigma pioneered the large-aperture, APS-C format, standard lens category with its 30mm f/1.4 lens in 2005. With new optical configurations of nine elements in eight groups, as well as rounded aperture blades, this updated lens delivers pleasing sharpness and a beautiful bokeh background. Its minimum focusing distance is 11.8 inches and its maximum magnification ratio is 1:6.8. The lens’ optimized power distribution helps to minimize field curvature, prevent a loss of image quality at the edges of photographs and produce outstanding image quality. Its double-aspheric lens minimizes spherical distortion, astigmatism and coma, and its rear focus system prevents focus-dependent variation in aberration. Together, the new optimized auto focus (AF) algorithm and rear focusing system ensure smooth and accurate focusing. The new 30mm f/1.4 is also compatible with Sigma’s new USB Dock, which will enable firmware updates and focusing adjustments, is expected to be available in coming months.
