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
JPEG images from the Fujifilm X Pro 1 show noise is handled well across the sensitivity range, comparing closely to the Canon EOS 5D MK II and Nikon D700. From a sensitivity of ISO 3200 upwards the X Pro 1 exceeds the performance of all comparison cameras showing a better signal to noise ratio, this shows the camera is still capable of capturing decent image in low light conditions.
Raw Signal to Noise Ratio
At the lowest sensitivty value of ISO 200 the X Pro 1's raw images (after conversion to TIFF) have a better signal to noise ratio result than the Canon EOS 5D MK II, Nikon D700 and Leica M9. Despite the Canon EOS 5D MK II taking the lead at all other sensitivity values, the X Pro 1 still produces respectable results.
JPEG dynamic range
Raw dynamic range
TIFF images (after conversion from raw) again show that the X Pro 1 puts in an impressive performance for dynamic range, with only the Canon EOS 5D MK II getting similar results from ISO 3200 up.
