Late post ...
Just to illustrate the point that the camera has little to do with the result, Ian Kingsnorth recently advertised some E-1 photos he's published, on the DP Review Olympus SLR forum. Nice to see that the E-1 can actually be used for other things than cat photos and back gardens 😊
I've grown to quick like Olympus Studio, enough even to put up with it's slug-like response. The various tools provided to compare and sort images are very nice, such as the Lightbox, the labels, the A / B lists (these are all in Viewer too). The Batch mode helps get over the speed issues, although the way you set it up is a bit strange...feels a bit like a "non-linear Action Editor" for Photoshop. I would probably stick with the Studio RAW convertor even after Photoshop CS is updated, as the controls map more specifically to the camera.
Of course the huge fuss at the moment remains the PMA (unless you speak French in which case its the DXO Lab tests in Chasseur d'Images). There doesn't seem to be anything terribly exciting at PMA for E-1 users, but I have to say I think they hype around this year's show is at an incredible level. Digital photography progress just keeps accelerating, and more and more people are getting sucked into the "gear watch" addiction...me too.
