Woah really good timing. I have had my Da25mm send off for repair for loose Barrel and AF not working. Hopefully will be getting mine back tomorrow. PC board replaced, any insights as to what was happening?

If I had to guess: the damaged board was reporting incorrect aperture values to the camera, some old sigma lenses have this issue. The symptoms look similar.

This might be a bit off topic, but I just wondered if any of you have played with different "Program Line" settings. On the 25 I try to use maximum DOF. and matrix metering. Any comment?

sorry, i don't use any of those things. I am M mode and centre-weighted & spot metering primarily. Are you specifically asking what the camera algorithm is for max DOF?

Yes, since on the 645Z they are icons, but the manual describes them. I assumed most use them instead of the default setting.
