With an overall DxOMarkSensor Score of 67 points, the DSC-RX100 II is ranked 1stwith cameras using a 1-inch type sensor or smaller, and is even ranked highly against those with larger 4:3 sensors coming 4th overall, behind the GH-3, E-M5 and E-PM2. At 22.5 bits, the individual metric score for color depth is one of the best we’ve seen in a high-end compact with a zoom, and one with the largest Dynamic Range. When it comes to low light scores, only compacts with physically larger (APS-C) sensors such as the Canon G1X, Ricoh GR and Coolpix A outperform it.
