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).

    Hmm it’s going to be difficult for this bulky 19/2.8 to compete with a 20/1.7 pancake isn’t it ? What are they thinking, am i missing something ?

    • Rover

      they may have enough coverage for E mount (APS-C). maybe…

      • MJr

        I remember reading something ’bout that yeah. Only thing that makes sense. But it certainly is the cheap way out. If they’re going to make any money by not selling any tho … , well i doubt it.

    Finally, the rather slow 60mm equivalent everybody has been screaming for…

    • JG10

      Crap lenses.

  • Anonymous

    Slow and bulky… what’s the point?

  • Hélas, the 19mm is not a pancake …

  • These lenses would make some sense for SLR mounts (like Canon EF-S or Nikon DX). For MFT they are pointless.

    Please Sigma, give DSLR-users a 24mm f/2.0 or something that is missing in the lineups of Nikon, Canon or Pentax. Plenty of holes in the prime lineups of those systems.

    Don’t give us a “me too” MFT-prime.

    Must be cheap as chips.

    sonyalpharumos posted that it as coming to nex as well.
    and the 19mm looks to be about 43mm long (about 1.7 in).

    19mm does not look to bad for the nex (19mm and sonys 50mm would be a decent two lens set)

  • Ojojo

    1. DOA for m43.
    2. F2.8 standard lens for NEX?
    3. 19mm for NEX is useful (depending on your other lenses)

    1 out of 4 for Sigma’s first foray into CSC lenses – could do better!

  • I think my first thought .. uh .. mirrors .. other posters here–these don’t look very attractive at all for MFT. They look like they were designed for e-Mount (NEX). Unless these are really cheap-as-chips, why would anyone pick this over the smaller/lighter/faster Panny 20/1.7? And who has been clamoring for a 60mm-equivalent f/2.8 that’s not even a macro lens?

    Even on e-mount, 30/2.8 is disappointing when Samsung NX offers a smaller, cheaper, smaller, and still pretty decent 30/2.

    All that said, given their “EX” designation, I sort of expect the build & optics to be pretty decent. With relatively conservative specs I think there’s little excuse if they aren’t. And it’s good for the system that there are third-party choices. I imagine they’re wanting to address gaps not well-served by the OEM’s but they’re going to have to try harder to tailor to MFT if they want to make any headway there — one design for both MFT and APS-C probably won’t cut it when Panasonic and Olympus already have relatively mature line-ups. Better goal might be extended range or faster zooms, maybe a cheaper ultrawide. Maybe some more OS lenses for Panasonic. If they want something to do dual-duty, maybe something like a 12-35 ilk that could serve as wide standard zoom on MFT and ultra-wide on APS-C might work if size/weight/cost can be kept in check.
