I'd like to get back into photography - coming from a Nikon DSLR but really interested in getting something a bit smaller/less conspicuous. I can get a Panasonic GX1 new for roughly $200 sans lens or a Sony NEX-6 open box with the power zoom kit lens for right around $675. I have a couple of older Nikkors (50mm f/1.8, 105mm f/2.5, 35mm f/1.8) that I'd like to use so the focus peaking on the NEX really intrigues me, but the Panasonic appears to have better build quality and control layout and the M43 system has a ton of what appear to be excellent pancake lenses for not a lot of money. Those of you with experience with both systems, what would you recommend? My partner and I recently moved to central Florida so this camera will mostly be used for walkabout/street photography, Walt Disney World, that sort of thing.
