Sigma’s 60mm f2.8 DN Lens for Mirrorless Interchangeable Lens Cameras

Sigma announce the 60mm F2.8 lens on May 2, 2013. Here is the Press Release:

Sigma 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 that its new 60mm F2.8 DN Art lens for mirrorless interchangeable lens cameras (MILCs) will hit shelves in the United States mid-May for the street price of $239.

First revealed at the CP+ Camera and Photo Imaging Show in Japan earlier this year, the 60mm F2.8 is a new focal length in the Sigma lineup for both Micro Four Thirds and Sony E-Mount camera systems. It joins Sigma’s other DN lenses for MILCs: the 19mm F2.8 DN and the 30mm F2.8 DN.

“We’re constantly working to add new focal lengths to our lineup so photographers can have as many options as possible,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “This mid-range telephoto lens and its shallow depth of field will produce some very pleasing bokeh effects.”

As part of the company’s Global Vision category restructuring, the new 60mm F2.8 DN Art category 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. This lens also contains Special Low Dispersion (SLD) glass, which helps minimize axial and transverse chromatic aberration.

This lens incorporates telecentric optical designs and a linear, auto focusing motor that ensures accurate and quiet focusing for video recording. Featuring a metal exterior and a simply-shaped focus ring, it has varying textures to distinguish each part of the lens. Under its new manufacturing process, Sigma’s DN users can also choose between a black or silver finish to match their favorite equipment.
