DxOMark published their sensor review and test results for the Sony RX1R II premium compact camera. The new Sony RX1R II achieved an excellent DxOMark score of 97 points, with individual scores of 25.8 bits for color sensitivity, and it becomes the new compact camera king in DxOMark database.
From DxOMark Conclusion:
It isn’t any surprise to see that the 42-Mpix sensor in the Sony Cyber-shot RX1R II is related to the unit in the Sony A7R II; however, the performance improvements over the earlier models are significant and help regenerate some the interest lost to the superb Leica Q. In terms of sensor dynamics, the Sony has the upper hand, but whether that and the inclusion of a built-in EVF is enough comes down to personal choice.
While the two models adopt equally impressive lenses, it is the focal length, and thus the field of view, that’s likely to be most important single determining factor when choosing between the two. If you like the 35mm focal length, then the upgraded sensor in the Sony RX1R II makes a compelling case.
Sony RX1R II vs RX1R vs RX1: Impressive low noise levels
Both the RX1R and RX1 achieved excellent scores for sensor dynamics, and the new sensor improves on those earlier models. Not only does the new sensor have a higher pixel count, it has lower noise levels overall, which contribute to the higher color sensitivity of 25.8 bits, including a mid-range boost from ISO1600 onwards and an impressive low-light ISO score of 3204 ISO. That’s close to a half-stop improvement over the earlier models. Sony has enhanced the dynamic range at lower ISOs so that it is now closer to the original RX1’s results for landscape photographers looking for the widest possible exposure latitude. At the same time, Sony has also significantly boosted high ISO dynamic range by around +1 stop from ISO1600 through the maximum, which should please available-light photographers.
Sony Cyber-shot DSC-RX1R II vs. Sony A7R II vs. Leica Q Typ 116: Excellent high ISO DR
In this group, the 24-Mpix CMOS sensor in the Leica Q is outshone by the dynamics of the Sony pair, which incidentally share a related sensor; however, the Leica sensor’s performance remains impressive. Significantly, the Sony RX1R II has a 1.5-bit advantage in color sensitivity at base that continues through ISO6400, which a good indicator of the lower noise levels of the BSI CMOS adopted by the Sony pair. Few could argue that the Leica Q has good dynamic range, especially at high ISOs, but with the exception of ISO800-1600, it doesn’t quite have the same latitude as the Sony, which has a wider dynamic range at base through ISO400, and then from ISO3200 onwards. Sony’s BSI CMOS has class-leading noise levels, and for our low-light scores, that translates to the RX1R II having about a half-stop advantage in noise over the Leica Q.
