Press Release:

Sigma Corporation announces four new lenses at CP+ Camera and Photo Imaging Show 2013

Sigma 60mm F2.8 DN

APS-C format, E-Mount and Micro Four Thirds lenses feature sleek new ‘Art’ product line design

YOKOHAMA, Japan Jan. 29, 2013Sigma Corporation of America a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, today announced the release of four new lenses for the ART product line, including three lenses for mirrorless interchangeable lens cameras and one lens for DSLR cameras with APS-C size sensors. This announcement comes at the start of the CP+ Camera and Photo Imaging Show 2013 this week in Yokohama, Japan.

The new and updated Sigma lenses include the 30mm F1.4 DC HSM, which will be available in Sigma, Canon and Nikon mounts, and the 30mm F2.8 DN, 19mm F2.8 DN and 60mm F2.8 DN lenses, which are available for both Micro Four Thirds and Sony E-Mount camera systems. Pricing and availability on all of these lenses has yet to be announced.

The 60mm F2.8 DN lens is entirely new to the Sigma lineup, while the 30mm F1.4 DC HSM and the 30mm F2.8 DN and 19mm F2.8 DN lenses are existing focal lengths that have been redesigned with enhanced optical performance and included as part of Sigma’s new Global Visioncategory restructuring. All three DN lenses incorporate telecentric optical designs and a linear, auto focusing motor that ensures accurate and 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 favorite equipment.  

Sigma 30mm F1.4 DC

“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.”

Here are more details on these new lenses from Sigma:

  • 30mm F1.4 DC HSM – Sigma pioneered the large-aperture, APS-C format, standard lens category with its 30mm F1.4 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 angle of view is equivalent to 45mm on a 35mm camera (which is 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’ 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 F1.4 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.
  • 60mm F2.8 DN - Featuring the natural perspective of mid-range telephoto lenses, together with a shallow depth of field, this lens allows the photographer to capture a single part of a subject with great bokeh effects. It has an angle of view equivalent to 120mm on the Micro Four Thirds system and 90mm on the E-mount system (35mm equivalent focal length). The minimum focusing distance is 19.7 inches; the maximum magnification is 1:7.2. This lens also contains Special Low Dispersion (SLD) glass, which helps minimize axial and transverse chromatic aberration.
  • Sigma 19mm F2.8 DN – This high-performance, wide-angle telephoto lens has an angle of view equivalent to 38mm on the Micro Four Thirds system and 28.5mm on the E-mount system (35mm equivalent focal length). As a wide-angle lens with excellent mobility, it is ideal for studio photography, architecture and starry skies. Its minimum focusing distance is 7.9 inches and its maximum magnification is 1:7.4.
  • Sigma 30mm F2.8 DN – This high-performance, standard telephoto lens has an angle of view equivalent to 60mm on the Micro Four Thirds system and 45mm on the E-mount system (35mm equivalent focal length). This lens, which is perfect for casual and formal portraiture, documentary photography, travelogues and everyday shooting, includes a double-sided aspherical lens that enhances its optical performance. Its minimum focusing distance of 11.8 inches and its maximum magnification is 1:8.1.
