John, those are very nice. I am considering the EP-1/2 or the GF1 in the near future. Did you find any trouble with the focusing with your EP1. I think it's known the GF1 focuses faster, but I wonder if it would be that noticeable.
I just downloaded some full size image sample jpgs, and found the EP1 samples to be a little better than the GF1. I have to say I wasn't quite impressed with either samples I saw compared to my now old EOS1D mark II. I was hoping to get at least that quality in a smaller camera so I don't have to carry that big thing around. I wonder if the RAW files are a different story...
I am also considering the DP2, but lower resolution and very slow focus turn me away.
