Sony Cyber-shot DSC-RX10 II review – Performance: Noise
There seems to be little quantifiable difference in the noise levels between the RX10 and RX10 II. Thankfully, that means the sensor produces lots of fine detail with little noise at low sensitivities up to around ISO 1,600. However, I would suggest that ISO 3,200 is about as high as you want to shoot and ideally you should stick below ISO 800.
