New: Sigma 19mm f/2.8 and 30mm f/2.8 EX DN lenses for Micro Four Thirds camera
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).
Sigma 30mm f/2.8 EX DN: Extending a mere 1.5″ (38.6mm) from the front of the camera is Sigma’s new 30mm f/2.8 EX DN. This lens has a full-frame equivalent FOV of a 60mm lens when used on a Micro Four Thirds format mirrorless camera. The new Sigma 30mm f/2.8 EX DN features seven elements in five groups including dual aspheric lenses and a double-sided aspheric lens that help control edge sharpness and chromatic aberration. As with Sigma’s new 19mm f/2.8 EX DN lens, the new 30mm f/2.8 EX DN lens includes Sigma’s newly developed linear AF system for smoother and quieter operation, Super Multi-Layer coating for optimized contrast levels and reduced flare, a 46mm filter thread, internal focusing and a minimum focusing distance of 11.8″ (30cm).
