You can tell that the weather has been somewhat dull lately, as here's another comparison test!! This time between a Panasonic G3 fitted with an Olympus 12mm f/2 and a Sony NEX-C3 fitted with a 16mm f/2.8. The comparisons are for performance at all ISO's, both from raw and jpg. and how the lenses perform at their various apertures.
