"Despite the raves that recent micro four-thirds and Sony E-Mount cameras have received of late, there's still a dearth of lenses for the fledgeling systems compared to their more entrenched counterparts. Luckily, Sigma's just added to the pool of autofocus-equipped models for each system: updated 19mm F2.8 DN and 30mm F2.8 DN models along with an all-new 60mm F2.8 DN telephoto lens. Each Japan-made model has a \"telecentric\" optical design to minimize CMOS color issues, a metal exterior with silver or black color options, and a linear autofocus motor that Sigma claims is quiet enough to use for video. Meanwhile, the imaging outfit also announced an updated 30mm, F1.4 DC HSM model for Canon APS-C, Nikon DX and its own Sigma mount. All that's great news, though we're still waiting for an AF/electronic F1.4 or faster lens for E-Mount (there's only one on MFT as well) -- though this might tide us over, in the meantime.

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.

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 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.      \"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.

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.     &amp;middot; 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.
