A few days ago, I posted some comparisons between carefully scaled pictures of the GH1 and GF1 which I found helpful in choosing which Micro Four Thirds camera to buy.
Today I went to my local camera store to pick up an Olympus M. Zuiko 17mm f/2.8 (for use on the GH1 in the upcoming Sigma DP2 shootout) and took the opportunity to snap a couple comparison shots of the GH1 and E-P1.
The 17mm Zuiko lens transforms the GH1 into a remarkably small and light camera.
