Hi Wendy, I have the 70-200 f2.8 EX Sigma (one of the latest models), and as a lens its fantastic in built, sharpness, contrast and very slightly colder than SMC glass.
HOWEVER (perhaps of general interest to the PDML), the lens seems to be having a problem with my MZ-s in terms of autofocus. It tends to be slightly out of focus when using the Autofocus, especially noticeable at the 200mm end. Now, I've tried the lens on the z-1 and it works fine, I've tried Pentax lenses ans the 28-70 f2.8 Sigma on the MZ-s ad it works fine. So: rapid conclusion is that there may be a problem with the compatibility of this lens with the MZ-S. I have sent it to Sigma Italy, they have verified the presence of a problem (with more than one 70-200mm f2.8 lens) and they are corresponding with Japan to see if its a problem with lens software. So far they cannot find out what's wrong. but are working on it.
