I've never owned a Panasonic camera although I was an early adopter of M4/3 with an Oly E-P1. Recent kits include Leica M9, Sony RX1R, Canon EOS 1DIII, and many, many others. I have two cameras now, a Leica X2 and this newly acquired Lumix GM1 w/24 1.4 and Oly 45 1.8. Just another tool but I think the IQ is as good as anything I've owned. I'm having fun shooting again after a while of stagnation.
