Were your inconsistency issues based on subject distance, lighting or both? Or were it just generally inconsistent?
If I aim my S35 at a rich texture brick wall, and then take 10 shots (refocusing between each shot), I'm always getting 4 - 5 missed ones. Even though I have my camera on a tripod.. Should not happen. :/
I am traveling right now, but I think I'm gonna send my lens to Sigma when I get back home.
Mine were lighting based, but to be honest it could have also been distance based. I didn't really test like you did though with 10 of the same shots. I will do that with the new lens though.
