Sigma optics are usually compatible with bodies available at the timethe lens is out. But older or newer bodies often have problems.
It certainly confirms the quirks I see with my EX 70-200/2.8. Not a big deal, though. It only reports the wrong aperture when used with a TC.
First time I read about Sigma reverse-engineering the mounts was around 1998, on this list. :-)
