Somehow this one slipped past me until now. But I have to say, this is very interesting. It's one thing when Sigma started making high quality "art" lenses that were equivalent or maybe just a little shy of the specs of the comparable Canon lenses. But now they're starting to make certain lenses with focal length/aperture specs that surpass anything offered from Canon themselves. I was disappointed to see mediocre reviews for their new 12-24mm lens, suggesting they still don't quite have the R&D power that Canon does. But it will be very interesting to see how this lens is.
