Here is a shot I took with the rx100 m3 in Peru. It's a street scene just after sunset. Hand held at 1/30s, ISO 2500. The first is unedited. To the right, I lifted the shadows on the JPEG. Shows that the file is quite flexible, even in jpeg and not raw.
I have an OMD EM5 and GX7. The RX100 M3 is comparable in low light ability.
The bandings in the sky is quite evident after the post processing though..
