SIGMA 70-210MM F4-5.6 on DSLR


Can someone tell me if the Sigma 70-210MM F4-5.6 UC-II AF should autofocus on a Penatx DSLR? I was under the assumption it would. Just received a new one and it will only focus manually. I tried it on two different bodies. Is there a setting I'm neglecting to set on the camera? I do have the K100d setup to accept Manual lenses and have had no problem using them.

Thanks in advance,
