Not a lot to say here, really - the new sensor and lens combination is obviously bringing more than just more pixels to the image - there's measurably (and visibly) more detail in the S2's images when viewed next to the S1 output. It's not a huge difference, but the diagonal lines in the queen of heart's hair look a lot less jagged, overall sharpness is better and edge-to-edge consistency is improved. Interestingly the noise levels are very similar.
