Just for the sake of curiousity (I already bought GX1). If we put a NEX 5N or NEX 7N on the kit lense vs newer sensor M43 (EM5 and GX1) on a good prime, either 20mm F1.7 or 45mm F1.8. How do they compare in the following conditions - 1. Low light photography (will the brilliant APC-S sensor with not so good kit lense do better than M43 combo with good prime lense here?) 2. Dynamic range.. 3. Sharpness and details of pictures in normal lighting conditions.
