The signal to noise ratio figure shows the proportion of random image noise there is in the camera's images. The higher the figure the better.
JPEG signal to noise ratio analysis: Again, the Sony RX1R II's high resolution appears to have no impact on its noise levels. Only the Fuji X100T can match its JPEG signal to noise ratio across the full ISO range.
Raw (converted to TIFF) signal to noise ratio analysis: The raw results tell a slightly different story, and here the RX1R II is closer to the rest – if anything, the Leica Q has a slight advantage in the medium ISO range, though loses out slightly past ISO 6400.

Amy has been writing about cameras, photography and associated tech since 2009. Amy was once part of the photography testing team for Future Publishing working across TechRadar, Digital Camera, PhotoPlus, N Photo and Photography Week. For her photography, she has won awards and has been exhibited. She often partakes in unusual projects - including one intense year where she used a different camera every single day. Amy is currently the Features Editor at Amateur Photographer magazine, and in her increasingly little spare time works across a number of high-profile publications including Wired, Stuff, Digital Camera World, Expert Reviews, and just a little off-tangent, PetsRadar.
