Gentlemen, it´s just a lens ... A lens we have only seen in pictures ... we have seen a few graphs and a couple of totally uninteresting images ... Let´s wait with the insults and bombastic conclusions until we have had a chance to try it out. Or at least until we have seen a couple of proper reviews. What we have seen so far are just preliminaries ...Sigma's famous statement: it wasn't looking to surpass Nikon and Canon, but rather the Zeiss Otus 55mm f/1.4 has a way to go judging by the graph in the review. I would have expected the FF graph to look like the 7D graph based on this bragging. The Otus' whole thing is sharp corners at f1.4. That's expensive to achieve.
You don't seem to know how to read the graph or what a typical graph is. This lens actually has LESS falloff in resolution between the center and corners than the Zeiss Otus, and 3 times less falloff in corner resolution than a typical competitor. On top of that it's as sharp in the corners wide as most 50mm lenses are stopped down in average resolution at f/2.8. For all intents and purposes it's tack sharp on full frame in the corners wide open. All lenses have some sharpness falloff in the corners, the Otus has significant drop, but for both lenses we are talking about being ridiculously sharp in the center and nearly ridiculously sharp in the corners. The Sigma is 2-5 times sharper than any other 50mm prime with autofocus in terms of average resolution, so the whole image is very clear.
You're also missing the point of their quote. The Sigma 50 A is not competing with canon or nikon it's competing with zeiss and makes Canon and nikon obsolete. That's the point of the quote, and that's what they accomplished.
Dude, you are embarrassing yourself.
I actually prefer the old Sigma 50/1.4 EX DG HSM over any other fast 50 with AF. It's bokeh and sharpens wide open just wins. If the new one is meant to be a replacement for it, then it cannot cost more than $1000. IMHO, Sigma has already surpassed both Canon and Nikon 50/1.4, so now they are aiming for the crown (vs. the Zeiss). Otus optics may be better, but I'm sure that many will prefer Sigma for the price.
P.S. I hope Samyang will join the fast 50 competition soon.
