I just bought the Panasonic DMC-GF3 (on sale!) as a traveling companion in place of my 4-yr-old Nikon D60. Just shooting some first pictures of spring blossoms and flowers to get the hang of the camera. I have been impressed by the quality of the images so far and the bokeh of the kit 14-42 lens is very, very pleasing indeed. I was somewhat surprised by that. It shoots RAW and the RAW files when loaded into LR4 do not really need any tweaking because they look so good right out of the camera. That was a surprise to me too.
I know that a new upgrade model to this one (the GF5) has been announced, but the GF3 got pretty good reviews and the price was very right. Anway, I think that looking into the smaller mirrorless systems like the Olympus PEN, Panasonic Lumix, or Sony series would be good way to go, too.
