anyone else have this on a crop? im wondering if its wide enough to walk around with.. im torn between this and the 20, even though macro is a definite +++ on this one!
I tried this, the Canon 24L II and the Siggie 20 1.8 on my 40D a few weeks ago. Although I ended up buying the Canon 24L my definite second choice would have been the Sigma 20 1.8.
Both Siggies did a fine job but the 20 was just more of a pleasure to use and I liked the extra room on the wide end. It was a tough decision to go with the 24L - I would have been very very happy in most shooting scenarios with the 20 I think (and a bit less poor, too!)
