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.
JPEG signal to noise ratio
These results show that the Fuji X-F1's JPEG files have a similar signal to noise ratio to those from the Canon S100 at the low sensitivities, and the Panasonic LX7 in the mid range. It sits below the Sony RX100 after ISO 200, and above the Olympus XZ-2 and Fuji X10 throughout the whole range.
Raw signal to noise ratio
The signal to noise ratios of the TIFF images (after conversion from raw) from the Fuji X-F1 are better than the JPEG images, this time producing the most impressive results of the group at ISO 100-400, before the Canon S100 overtakes it in the mid-range. The Sony RX100 also performs better than the Fuji X-F1 at ISo 1600 and above, while the Panasonic LX7, Fuji X10 and Olympus XZ-2 are lower down in the performance league.
JPEG dynamic range
Again, the Fuji X-F1 sits roughly in the middle of the table for its JPEG results for dynamic range. The Olympus XZ-2 comes out top at the low-to-mid range, and the Sony RX100 takes the lead at the higher sensitivities. The Panasonic LX7 produces similar results to the X-F1, and the Fuji X10 and Canon S100 sit at the lower end of the table.
Raw dynamic range
This chart indicates that TIFF images (after conversion from raw) from the Fuji X-F1 have the strongest dynamic range of all the cameras at the lower sensitivities, but are beaten by the Sony RX100, Fuji X10 and Olympus XZ-2 from ISO 800 and up. The Panasonic LX7 and Canon S100 sit below them in the table.
