We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using DXO Analyzer software to generate the data to produce the graphs below.
A high signal-to-noise ratio (SNR) indicates a cleaner and better quality image.
For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.
We have compared the RX10 with the RX100 II, with which it shares the same sensor, as well as some other traditional bridge cameras currently available on the market - the Sony HX300, the Panasonic FX200 and the Fujifilm X-S1.
JPEG Signal to noise ratio
Here we can see that the RX10 clearly beats the other cameras on test, with the exception being the RX100 II with which, as we would expect, it is very closely matched. At the very top end of the sensitivity run, the Sony HX300 just pips it, but it sits comfortably above the Fuji and the Panasonic throughout the sensitivity run.
Raw (after conversion to TIFF) signal to noise ratio
It's a little harder to compare raw format files, since so few bridge cameras offer this facility. However, we can that again it is reasonably closely matched with the RX100 II and shows a consistent performance across the range. The Panasonic FZ200 beats it at the lower end of its sensitivity scale (ISO 200), but the Sony overtakes it from the mid-range of ISO 400 and above.
JPEG dynamic range
The RX10 puts in a consistent performance across the sensitivity range, producing an almost flat graph. It is beaten at the very lower end of the sensitivity range (ISO 50-100) by the Panasonic FZ200, Fujifilm X-S1 and Sony HX300, but from ISO 200-400 upwards it either matches or beats the other cameras on test. The RX100 II, with which it shares the same sensor puts in similar scores, if a less consistent overall performance.
Raw (after conversion to TIFF) dynamic range
As we might expect, the RX10 puts in a reasonably similar performance to the RX100 II for raw format files (after conversion to TIFF) here. It beats the Panasonic FZ200 at every sensitivity too.
