I'm planning a visit to Yellowstone and Grand Teton and bringing my 5D3 with the requisite landscape lenses, my SL1 is my backup EF body. I'd like to leave the big whites home and carry a bridge camera. Both the Leica and Lumix (identical specs) fit my bill as 25-400mm zoom with f/4 aperture. Does the Leica have a superior IQ to the Lumix? Is the Leica being a crippled version of the Lumix make it less desirable given the $450 premium price? I'd like to hear ONLY from those who have shot either or both bridge cameras.
