Normally I would have jumped on the Sigma, but I think I might go for the 35 f/2 IS. IQ looks good, even if not quite as good as Sigma's, although the Canon seems to have better bokeh or at least oof highlights. I just love the thought of 4 stop IS for low light work in dark interiors of galleries etc, where no tripods are allowed. Also the size and weight are very nice. If I were going to be picky, I wish Canon had made it f/1.8, but 1/3 of a stop is barely going to be noticeable.
