What I've noticed is that my Panashita fares much better with lower ISO - and formerly Matsushita now Panasonic provide the sensors for Olys if I'm not mistaken. I was only trying to help you find that out: lower ISO give bettter results, just as in the good old days. Sorry again if it meant any uneasiness or trouble for you. Bien amicalement Philippe PS: "mon ami" is what I'd call you in my mother tongue, earnest - so I guess referring to Ted was just a sort of winking at both of you, whom I respect most.
