i just got the sigma 50. do you have any focusing problems with it?
its been back/front focusing on me a lot lately. kinda think i needa get it calibrated.
Which body are you using it on? When I do my little "tests" it will front/back focus no matter how hard I adjust it... but when I actually take real photos it just works... usually. Here's one I was impressed with - (view the original)

from that distance, at f/1.8, the DoF is pretty narrow but the 1D IIn NAILED it, even though it had been spotty with my little "tests", and that body does not allow for focus adjustment.
Any particular conditions you're noticing it having problems under? With the AF assist beam from the flash, and the otherwise dark "club", I usually get some razor-sharp and perfectly focused images... where as in natural light it may miss.
