    If that 14mm has well corrected coma it will be a dream lens for nightscapes.

    is the Contemporary line of lens a step below the Art line? or is it a bit of marketing puff for the regular line?

    A 14mm f/1.8 for full frame sensors? That sounds impossible by physics, but if they pull that off…wow.

      well you know obviously nothing about physics and optics…..

        Sweet, another condescending internet knight in shining armor! Thanks for the nice comment. You’re right, I don’t know a whole lot about physics…but I know a bit about optics, and I know that the widest aperture available for any full frame lens in the 14mm range is f/2.8. And I know that f/1.8 is a whole stop and a third faster than f/2.8, which sounds unlikely, because why wouldn’t any other camera manufacturers have capitalized on that already if it were possible? Please, enlighten me, physics and optics master…

          The reason such a lens was not made before was because it then would be prohibitively expensive to produce. Now, the latest 5-7 years not only aspherical lenses but also other types of advanced glass (that didn’t exist before) are much more affordable and available.

          Programs for lens design have improved. Now even a novice with such a program can design a lens that measurs well.
          Glass production technology simply have improved a lot.

          Also before there were no big market for a fast super wide lens. Most would use such a wide lens stopped down to f/8-11. The main reason for the f/2.8 aperture was to have enough light for focusing with an optical SLR finder.

          Now however there is a great enough interest in astrophotography for Sigma to produce a 14/1.8 lens. And while this as far as I know is the first FF 14mm f/1.8 lens we have already seen some fast super wide lenses for smaller formats, like the Olympus 8mm f/1.8 fisheye. So this lens is just a part of a new trend with lenses breaking new records.

            Thanks for the thoughtful and educational reply! That answers my question. It would be awesome to see a 14mm f/1.8 for full frame, I just didn’t think that was possible. But if Olympus can do a 16mm 1.8 (equivalent), than I suppose 14mm is not too far off. Hopefully it performs just as well as the rest of the ART line.

    dat 100-400 seems to be compact like it should be!
