Here is what PhotographyBLOG concludes about the GF1:
… the Panasonic Lumix DMC-GF1 takes most of the good points of its bigger brothers, the G1 and GH1, and literally squeezes them inside a smaller, more compact-camera-like body. The fantastically well-implemented Live View, lightning fast auto-focus, excellent image quality and added bonus of 720p video makes the GF1 a great camera for beginners and more serious photographers alike.
That’s some high praise. Another video after the break.
