Unlikley! Pentax and Sigma have never had a working relationship as
exists with Tamron and Tokina. I think Sigma have even had to
reverse engineer any Pentax mount lenses to maintain full
compatibility ...I have some EX series and never had any problem

But I think they sell their cameras with Sigma kit lenses in Australia, don't they.
