I have the Pentax FA 50mm f/2.8 and A* 200mm macro lenses and the Sigma 100mm f/2.8 EX autofocus macro lens. While the build of the Pentaxes is better, the Sigma works great too, image quality is fine, lots of contrast too. The only thing I do not like about the Sigma is the mechanism to switch between MF and AF, it is a clutch built into the focussing ring (like the FA* lenses have) but operation is too smooth. Just picking up the lens from a camerabag will often change the setting. Otherwise it is a great performer! I have been using it a lot on the PZ1 and the MZ-S. I also use it on the *ISTD, but prefer the 50mm in more shots than with the film cameras. (75mm equivalent).
