DSLR Check has published a new shadow noise testing between Sony RX100, Fuji XF1, Nikon 1 V2, and Olympus XZ-2. Basically this is a dynamic rage test. One of the shot was taken simply at ISO3200, then the second series was taken at ISO400 but exposure pushed by +3EV, and once again at ISO200 with +4EV. You need to ignore the chroma noise in these pictures – look for how much details each camera is capable of retaining, both in terms of details and colors.
In theory, since both the RX100 and Nikon 1 V2 uses 1-inch sensor, they should come out ahead, followed by Fuji XF1 (1/1.5-inch sensor) and lastly, the XZ-2 (1/1.7-inch sensor). In practice, I think the RX100 came out as the winner and the V2 second, but it wasn’t obvious if XF1 came out ahead of XZ-2. XZ-2 shots did produce more noise but also appears to have retained more details so once noise reduction algorithms are applied to these images, I have a feeling that XZ-2′s image will look cleaner.
