I always like to comment on this lens because I was so impressed by it when I bought it, and as time passes I just enjoy it more and more. It does have some distortion at the wide end, but its very nice and sharp (esp. wide open, but tack sharp at f4) and has some of the nicest bokeh I've seen on a zoom aside from maybe the canon 24-70 L. Very portable too. You'll love it, and more so as time passes.
