Cons: My copy had a back focus issue of 50mm, which meant the main subjects emerged out of focus.
Pros: I returned the lens to Sigma, who fixed the problem and calibrated it to my SLR (which accompanied it) and returned both within 4 days. Image Quality is outstanding after f4 (On a DX). IQ is great from wide open as long as you know the limitations of the lens and how to frame your shots. 82mm filters expensive - however the Heliopan Polarizer mated to this lens produces stunning images in colour.
Summary: A wonderful piece of glass - once the back focus issue was resolved. Colour images (bright outdoor landscapes) with the heliopan 82mm polarizer are stunning. Fast AF, Great Build and Superb Value.

Cons: Corner performance is weak until about 7.1 -
Pros: Dazzling center performance at all apertures Nice build quality 82mm Filter size gives the lens a seriously professional look. HSM is as fast and as accurate as the USM in any Canon Excellent low light performance
Summary: If you want a solid alternative to the Canon 24-70MM L, look no further. The reality of photography is if the center performance is solid, the average client isn't going to scrutinize the corner performance of your photos. The Sigma 24-70 HSM has simply dazzling center performace, with mediocre edge performance until about 7.1, after that the edges (even on a full frame 5D) come into perfect focus. I've only had the lens for a few days, but used it at an event in low light - results were better than I expected! I waffled over this lens and the Canon for about a month and finally settled on the Sigma as it was $500 less and came with a 4 year warranty instead of Canon's 1 year warranty... Time will tell, but as of right now, I think I made the correct choice.
