The photographers skill may not be the greatest but the images are not that sharp at full view. Looking at the RAW files from the test scene here on DPR, the camera is capable of sharp detailed shots. Compared to the RX100, the V3's images are sharper. It appears the Sony may cooking the RAWs by applying some NR which may soften detail a bit. The Sony images are even more soft off axis due to the lens.
I'm not saying the V3 sensor is as good, it is just not as behind as people make it out to be.
