The G3 was my upgrade from the GF1. It had everything that was missing that I wanted. It has the same sensor as the GX1, but has the EVF and flip out screen built into the camera. Easy to carry and if you get either the 14mm or 20mm lens, you can carry that, an extra battery and memory card in a very small case. Great little camera, and cost the same as the GF1 you are looking at. Last year Luminas Landscape reported on the G3 as the best m 4/3 camera to date. But that was last year, but for the price it has got to be the best deal going. I have loads of photos online using both the GF1 and G3. Loved both of them, but the G3 is a much better camera.
