About 4 years ago I had a GF1 with 20mm pancake as a go anywhere camera, very nice.
Today I have a m43 system based on a couple of EM1's, just because the camera is small and has very good ergonomics for me. No doubt something like a GX7 with a small lens is a great kit. The problem is, at least in my country (Portugal), there is hardly any shop that has Panasonic cameras and lenses... The best photo shop in Lisbon, that caters for professionals and a full supply of Canon, Nikon, Leica, Sony, and Olympus, stopped selling Panasonic, Ricoh, and other smaller brands. Sign of the times, they now are strongly pushing Samsung.
I still think that Panasonic makes fantastic cameras and lenses, I have a Leica 25mm lens, but I had to buy that from abroad... I was looking into buying a 12-35 lens for travel, can not find it anywhere.
