Two new Micro Four Thirds lenses from Sigma will be announced tomorrow:
Sigma 19mm f/2.8 EX DN: When used on a Micro Four Thirds format mirrorless camera, Sigma’s new 19mm f/2.8 EX DN has the effective FOV of a 38mm lens on a full-frame DSLR, which should appeal to street photographers and photojournalists. Regardless of your choice of camera, the Sigma 19mm f/2.8 EX DN features eight elements in six groups that include three aspheric lens surfaces to correct optical distortions, color aberration and unwanted field curvature. The new lens also sports an internal focusing system and Super Multi-layer coating to reduce flare and ghosting while maintaining high contrast levels even when set at wider apertures. Other features include a new linear AF motor that eliminates mechanical gears or drives for quicker, near-silent focusing, seven rounded diaphragm blades for an attractive blur in out-of-focus areas, a 46mm filter thread, and a minimum focusing distance of 7.9″ (20cm).
