The signal to noise ratio is a scientific measurement of the amount of digital noise in the image. The higher the number, the greater the difference between real image data and background noise – higher numbers are best. This is measured using DxO Analyzer in laboratory conditions.

JPEG signal to noise ratio analysis: This time the Sony RX100 IV has a slight advantage over the G5 X, but all four cameras are so close together that the differences may not be apparent in real world photographs. Noise levels in JPEG images will depend heavily on the degree of noise reduction applied by the camera.

Raw (converted to TIFF) signal to noise ratio analysis: Here, the differences are greater. The G5 X and RX100 IV are much closer together and the Panasonic TZ70 repeats its unexpectedly good performance from the dynamic range tests.
