Well, Sigma makes its lenses to work with other manufacturer's bodies (since there are not many Sigma bodies around), so they logically ~have~ to be nice to Pentax (etc.) users. On the other hand, Pentax does not support the use of its bodies with 3rd-party lenses - after all, Pentax wants you to buy jen-you-wine Pentax lenses. So, I would ~not~ expect Pentax to offer friendly advice about how to properly use any Sigma lens on a Pentax body. However, Pentax should ~not~ be rude to you - the reply should say "sorry", but it should be a polite "sorry (in my humble opinion) - rudeness will not win additional Pentax sales (either for bodies or for lenses or for accessories). That's my two f-stops worth... Fred
