Oh is this camera not out in the US yet? I tried it out in the store in Tokyo and liked it quite a bit. Not that this helps anyone :)
nicolaiecostel: Well, it''s not really going to be as good as the nikkor, nor as good as the canon. i tested them both and they are really good. I also tested the 85 1.4 AFs nikon and it's stunning, a bit better than my sigma 85 1.4. The canons are also very good, with some CA wide open though. This sigma will be nicely sharp at 1.4, with minimal CA and spherical aberration, decent color rendition. The nikkor will render color better, will have better contrast wide open, will have less CA and you will probably never have to worry about calibration on it. At twice the price. The choice is really up to the user, and since I cannot afford or justify the nikkor, and my 35 f/2 is limiting me somewhat, this 35 sigma seems like a logical choice.
you mean you tested the sigma 35 1.4 yourself against the canon and nikons?
luka3rd: Desirable!Don't be fooled by the price, though... it is "Art" series... there will probably be pro models which will cost much more!I assume that Art will be in the "low build quality / high performance" sector.

Art line = focused on best image qualityContemporary line = highest possible optical performance that can be accomplished in a compact size (size seems to be the priority)Sports line = action photography
