    More like a 27-53 actually, which isn't as impressive as a 24-70 (which is already a little bit limited for me), but f1.8 on any zoom should be fun. Sigma deserves props for this. Now a mu43 12-35m f2.0 doesn't seem so impossible anymore.

    I agree, 27-53mm is a very limited range as a constant zoom to be useful, but a 1.8 zoom is a break thru nonetheless.

    A M4/3 12-35mm f/2.0 would be great, but the lens diameter would be way too big for an OMD to mount on it comfortably :)
    Or you would like the Sigma's approach, 14-25mm f2?

    Nice specs. Let's hope manufacturers keep pushing the boundaries for faster while smaller lenses.

    Do we want to guess how much this lens will cost?
  7. $1500 :confused:

    Intruiging. An F2 zoom with a 24mm wide end would be very interesting, although I still prefer a little more range at the cost of aperture. Still, good to see some real creative engineering going on at Sigma!

  10. $800 is pretty good (as long as the IQ is up to par).

    That is price is pretty reasonable considering it is a constant f1.8, but I find 35mm to a bit short for my taste. I would prefer a 18-60mm lens, personally, even it if was at a constant f2, or started at f1.8 and ended at f2.8. Size actually looks pretty good too.

    Wonder if they could add a 0.67x speedbooster to this and a native m4/3 mount. That would make for a 12-25/1.2 zoom. I bet people would abandon the 12/2, 25/1.4 and even the 12-35/2.8 in droves for such a lens...

    No dice, unfortunately. It's an APS-C lens, the image circle isn't big enough to use the speed booster with it.

    I think his point was making a speed booster to mount APS-C lenses on m43. It would need a different ratio for the focal length reducer, but quite possible.

    It is true, however, that such a product does not exist currently.

    Actually you can use the speedbooster on an APS-C frame lens to mount onto m43. APS-C mirrorless can of course only use full frame lenses via the speedbooster but the m43 speedbooster takes crop frame lenses as well. I've posted elsewhere this Sigma lens with the speedbooster to m43 would make a very interesting combo, albeit a bit big!

    I wouldn't mind an 18-35mm f/1.8 (or even f/2) on μ43, especially since the short register distance would make it smaller than this dSLR version. Come to think of it, I'd have no problem with Sigma making a mirrorless version for both NEX & μ43. In that case, NEX would get a weird FL range and we'd get a normal one (unlike the 19mm & 30mm lenses).

    A 35-70mm-equivalent would be a nice range in conjunction with the 12mm f/2 and a 75mm f/1.8.

    Just because the lens is designed for APS-C doesn't mean the image circle isn't bigger. See e.g. the Tokina 12-24 which can even be used on full frame at 18mm.

    With a 0.67x wide converter, the Sigma will definitely cover a sensor with a diagonal of 19mm. 4/3 is 21.6mm, so it's not that big of a stretch.

    I'm interested to see how this lens tests out. The Phoblographer tested a pre-release version and it didn't sound great so hopefully they have some of those issues sorted out, though I wouldn't trust a Phoblographer review anyway.

    If it's a good lens, it'd make a great companion to the girlfriend's T4i ... maybe a Christmas present for her that I'll get to play around with as well!

    Assuming it is good optically, it is a nice alternative to the classic 28, 35, and 50mm equivalent primes. Physically larger, but you don't have to switch between three lenses.

    I could see it being popular with wedding photographers, perhaps.
