See full review at: Steve Huff Photos - Real World Digital Camera And Lens Reviews NEX-7 vs The Olympus E-P3 – The E-P3 focuses faser, has better lenses available, and has a cool retro design. In silver it’s simply beautiful. But it still has the same 12 MP sensor as the E-P1. The ISO noise is not far behind the NEX-7 at 1600 but the E-P3 does not have a built in EVF or a tilt able LCD. The 7 has a larger APS-C sensor, the E-P3 has a smaller 4/3 sensor. In all fairness the E-P3 is more fun to shoot and provides results that you just can not complain about. It has a cool factor and some serious mojo even with its limitations and I own it and am keeping it. BUT the NEX-7 is more serious with more potential. NEX has to win this if we are taking body to body. Lenses, Oly wins but then again, Leica glass just works better on bigger sensors, and the NEX-7 has the bigger sensor. I feel the G3 and GH2 would have been a good comparison, too.
