I rarely use GH2's touchscreen and ETC features. Hope Panasonic don't go higher than 16MP.
GH2 has shorter shutter lag and faster AF, but I like GH1 for static photo. 14MP magic? I'm gonna carry GH1 + 14mm 2.5 to capture this fall season.
GF1 is slower than GH1, but the static photo looks special. 12MP magic? I don't own it, but I like its rugged body. My GH13's body coating already began peeling off.
It's good to keep the good old GH1 or GF1 body. Especially GF1.
