Hiya MSF... sounds like you went to full frame heaven? :-)
I went on Holiday with the E-3 with that was my only camera... I felt a doofus walking round with a bloody big black thing over my shoulder when everyone else had a silver thing that fitted in a shirt pocket or the unbiqitous phone cam.
I think if I was buying a family or day-to-day camera now, I'd give the micro 4/3rds line a look. I belive they are pretty sexy!
Anyway, I came home from Poland and realised I'd left the noise filter on 'off'. [I am used to this as I'd get rid of noise with editting later] So a fair amount of these images [of Aushwitz, etc] are totally ruined as in any dark areas, there is no detail to any grass or trees, it's just a mass of indistinct bits. And I wouldn't say these images were under-exposed much.
It is a shame about Olympus or 4/3rds.. if only that sensor was bigger or they reduced the MP number to make better high ISOs.
Cheers
