Sigma is about to launch two new unspectacular lenses for the NEX system. The 19mm f/2.8 lens which at least from the size point of view is less interesting than the Sony 16mm f/2.8 pancake lens. And the 30mm macro lens which isn’t really a lens we needed since we already have the Sony 30mm f/3.5 lens. Damn Sigma, you should have done it better! You alreayd amke some awesome lens for Alpha mount! Like that nice 50mm f/1.5 for example. Next time ask SAR readers what they want 😉
Here is the press release text:
Sigma 19mm f/2.8 EX DN: 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 NEX 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).
And than there is that new Sigma’s APO Macro 180mm f/2.8 EX DG OS HSM lens. It is the fastest 180mm macro lens on the market today, by about a half a stop. But the specialness of Sigma’s new high-speed macro goes beyond its f/2.8 maximum aperture.
Shooting close-ups can be tricky, most notably when trying to capture life-size close-ups of skittish animals and insects without spooking them, or close-ups of small objects without casting your shadow on your subject. The longer focal length of Sigma’s 180mm f/2.8 EX DG OS HSM does away with many of these issues by allowing you to step back from your subject. The longer focal length also reduces optical distortions, which can be problematic when shooting close-ups, and also allows you isolate your subject from distracting foreground and background details, especially when used at its closest focusing points at wider apertures.
In addition to highly detailed life-size (1:1) image capture, Sigma’s 180mm f/2.8 EX DG OS HSM features three FLD glass elements, a floating internal focusing system, Super Multi-Layer coating, Sigma’s OS image stabilizing system, which enables the use of shutter speeds approximately four stops less than usually possible when shooting handheld, Hyper-Sonic AF focusing motors and a rounded nine-blade diaphragm for attractive bokeh.
