I don't think there is much chance of this lens being anything but, I hesitate to say the best. It has all of the bells and whistles including available software to calibrate it the way you want it. The F type elements are said to equal flourite. It looks like an all out attempt to be the best. I never thought much about a Sigma holy trinity. Odds are a 24 is next. Anyway, we'll see when it gets here.
Well Sigma has been saying lately "they are tired of being seen as lesser company" and that they want to really step up. IMO they sure are doing it. First the 50, then 85, now a 35. Not to mention the stellar 150 macro. Soon most of my lenses will be Sigma.
All I need now is a 24 and I'm in heaven. Oh and a 135 would be nice. And a 200 f/2. You know what, just copy all of Nikon's primes and make them Sigma,
