If there were no m4/3s, what you would you get, and why? We are all in the forum so we know how good m4/3s is, and we like it because of the following: *Many small bodies for $500 or less *Ahead of its time sensors *Cheap, small, sharp lenses - 20, 25, 45 *High quality native glass available - 42/1.2, 75, 12-40 *Can adapt virtually any lens including good, vintage glass for under $100 *Many good pancakes like the 14, 20, 12-32 *5-axis, weatherproof, viewfinder OMD type options *Low cost *Used 12MP bodies for $150 *"fun" lenses like body cap, 3d, and fisheye for cheap. No other system can claim size, price, quality, and versatility, but many can claim larger sensors, when, with all things considered, could technically be a bit better at high ISO and give better bokeh. So, you could get the boxy Sony A7 full frame thing and some lenses and spend $5000. Or you could get Fuji would seems like a good second choice to m4/3s except for cost and maybe size. Sony NEX has been around a while and although I don't like them, I'm sure they're doing some good things and could also be a second place to m4/3s in our hearts. DSLRs are an option, especially now that you can get that Sigma f1.8 zoom. There's full frame DSLRs like the Nikon D800 or DF. Then there's the Canon EOS-M or whatever their mirrorless thing is called, and Nikon and Austen Kucher's Nikon 1 system. Then there's whatever Pentax and other companies are doing that I haven't been keeping up with. I didn't want to make this a poll, but, if you couldn't use m4/3s, what would it be?
