DXOMark has published their test results for the Sony RX1. Within the article, they compare the RX1 against Nikon full-frame pair – D800 and D600. Given that both uses the Sony sensor, you expect similar results and the test proves that they do. The color depth and DR are very similar between the 3 of them. But for some reason, the RX1 performs not quite at the level that the D600 does in low-light photography, hence resulting in the 4th position behind them. They also compare the RX1 against other compact fixed lens models – Fuji X100and Sony RX100. Understandably, there’s no comparison in these cases – RX1 comes out way ahead in all aspects.
