I got GF1 for my coming trip to Europe, particularly for those shots in churches, since I know it's gonna be tough to get sharp images in such lighting condition. And they turned out great. The out-of-camera JPGs looks balanced, and I can still process RAW formats if I want/have to.
Size is definitely the big advantage to bring GF1 for a long trip when demanding image quality. I never own a DSLR, but when I see those huge cameras on other tourists, I know I made a right decision. Especially when you have maps, bags, drinks, jackets, and stuff in your hands while trying to make a quick snap.
The only drawback is that since the 20mm/f1.7 lens is not equipped with stablization feature, it's sometimes a challenge to find a good supporting point for the camera to get those poor-lighting shots. However, the wide aperture from the lens performed beautifully.
