 New Sigma lenses introduced at CP+ Camera Show : Sigma Corporation of America introduced four new digital camera lenses for the ART product line. The new Sigma lenses consist of three camera lenses for mirrorless interchangeable lens cameras and one lens for digital SLR cameras with an APS-C size sensor. This announcement comes at the start of the CP+ Camera and Photo Imaging Show 2013 in Yokohama, Japan. The new and improved Sigma lenses include the 30mm F1.4 DC HSM, which will be available in Sigma, Canon and Nikon digital camera 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.

Sigma lenses
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 Vision category restructuring. All three DN Sigma lenses incorporate telecentric optical designs and a linear, auto focusing motor that ensures accurate and quiet focusing for video recording. The new Sigma lenses 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 the colors black or silver finish to match their favorite equipment.
Sigma 30mm F1.4 DC HSM lens
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 Sigma lens delivers pleasing sharpness and a beautiful bokeh background. Its angle of view is equivalent to 45mm on a 35mm camera, its minimum focusing distance is 11.8 inches and its maximum magnification ratio is 1:6.8. The Sigma digital camera 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. The Sigma 30mm F1.4 DC HSM 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 Sigma 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 soon.
Sigma 19mm F2.8 DN lens
This high-performance, wide-angle telephoto camera 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, this Sigma lens is ideal for studio photography, architecture and starry skies. The Sigma 19mm F2.8 DN lens minimum focusing distance is 7.9 inches and its maximum magnification is 1:7.4.
Sigma 30mm F2.8 DN lens
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 Sigma 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. The Sigma 30mm F2.8 DN lens minimum focusing distance of 11.8 inches and its maximum magnification is 1:8.1.
Sigma 60mm F2.8 DN lens
Featuring the natural perspective of mid-range telephoto lenses, together with a shallow depth of field, this Sigma lens allows the photographer to capture a single part of a subject with great bokeh effects. The new Sigma camera lens 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. The Sigma 60mm F2.8 DN lens also contains Special Low Dispersion (SLD) glass, which helps minimize axial and transverse chromatic aberration. |
