Lenses : Sigma Corp. of America Debuts Four Art Lenses for CSCs and DSLRs
APS-C format, E-mount and Micro Four Thirds lenses feature sleek Art line design.January 29, 2013
The new and updated Sigma lenses include the 30mm f/1.4 DC HSM, which will be available in Sigma, Canon and Nikon mounts, and the 30mm f/2.8 DN, 19mm f/2.8 DN and 60mm f/2.8 DN lenses, which are available for Micro Four Thirds and Sony E-mount systems.
The 60mm f/2.8 DN lens is entirely new to the Sigma line, while the 30mm f/1.4 DC HSM, the 30mm f/2.8 DN and 19mm f/2.8 DN lenses are existing focal lengths that were redesigned with enhanced optical performance. All three DN lenses incorporate telecentric optical designs and a linear autofocusing motor to help ensure accurate, quiet focusing for video recording. They also boast metal exteriors and a simply shaped focus ring, with varying textures to distinguish each part of the lens. In addition, DN users can choose between a black or silver finish to match their equipment.
“We’re really proud of the super sharp lenses we’ve produced in the past year and these new Art lenses will continue to impress our fans and critics alike. They’re ideal for the landscape, portrait, still-life, close-up and casual photographer who values creative, dramatic outcomes above compactness and multifunction,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The lenses are entirely made in Japan and they boast the new product line’s sleek design and enhanced quality control. We’re quite proud of these changes—and additions—to our lens lineup; they’re further evidence of Sigma’s forethought in this fast-moving industry.”
Additionally, Sigma’s new USB dock, which will enable lens firmware updates and focusing adjustments, is expected to be available in coming months.
30mm f/1.4 DC HSM. 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, and rounded aperture blades, this updated lens is designed to deliver sharpness and a bokeh background. Its angle of view is equivalent to 45mm (similar to that of human vision), its minimum focusing distance is 11.8 inches and its maximum magnification ratio is 1:6.8. The lens’s optimized power distribution helps minimize field curvature and prevent a loss of image quality at the edges of photographs. Its double-aspheric lens minimizes spherical distortion, astigmatism and coma, and its rear-focus system aids in preventing focus-dependent variation in aberration. Together, a new optimized autofocus algorithm and rear-focusing system help ensure smooth and accurate focusing. The 30mm f/1.4 is compatible with Sigma’s USB dock. SRP: $499 in Sigma, Canon and Nikon mounts.
