Soft focus with Sigma on 30D?


Does anyone know if there is a focus problem with the Sigma 24-70mm 2.8 ExDG on the Canon 30D? This lens on the 30D has made me think I'm losing my mind at times.
I've been taking portraits for a while and usually have no problem with my results. I've used this Sigma lens on my 10D for a while and always get great results. However, I put this lens on my 30D and half the images are in focus, the other half look slightly out of focus. Put the lens back on my 10D and everything is perfectly in focus.
I can't figure this out. Why would half the images on the 30D be in focus while the others are out - and on the same settings.
And I'm not new to photography - I've been doing this a while, but I'm just stumped.
Anybody else had this problem with this lens?
