    Darn,..... So it looks like the 30mm f/2.8 is gonna be their first one. I don't know if they just sat around and tried to think up winch is the lest desirable lens µ4/3 users would want, or what. But I don't see a great need for that focal length, at that speed and I cant see it selling off the shelves, unless its a macro or at a low cost. Yet if it is, only a couple hundred dollars I think maybe some might buy it for a portrait lens. I wish it was faster tho. At that focal length the compact size alone of the lens is not enough for me unless its real cheep, I almost would have rather they just adapt their existing 30mm 1.4 lens so it would AF and function on my G1. I would get over the size if it was that fast and all the Auto functions worked well.

    But keep in mind that the Nikon is also a micro lens, plus 60mm on your D700 gives the ability to blur the background much more than a 30mm lens on our cameras.

    the speculation around the web is that it will be macro so f/2.8 is reasonable.
    The reason it's 30mm is that is about a 50mm field of view on an aps sized sensor. I expect Sigma will always choose focal lengths based on aps sensor cameras because that's what most mirrorless cameras will be. As m4/3 users we just have to accept being the odd man out.

    Typically sigma uses APS-C focal lengths. While this isn't ideal, it is an option.

    As long as they design the lenses to take advantage of the short flange distance the bigger image circle won't make too much difference. It would even have some benefit on an m4/3 camera, as the smaller sensor would be more in the sweet spot of the lens.
    If they just take existing APS-C SLR designs and change the mount, then the lenses will be bigger, especially the wides.

    My personal opinion is that mirror-less is the future, at least for sub-full frame sensor cameras. If I was Sigma (or Tokina or Tamaron) I'd want to get out front with lenses optimized for that format.
