DxOMark Sensor ranks cameras based on real-life photographic scenarios

Objective measurements of RAW image quality are an essential component of any analysis of digital cameras. DxO Labs has developed a new scale for digital camera image quality performance, called DxOMark Sensor, to serve as an additional tool to help photographers rank and compare digital cameras.

Essentials about the DxOMark Sensor scale:

  1. DxOMark Sensor measures only the RAW image quality of a digital camera; therefore, DxOMark Sensor is NOT an evaluation of overall camera image quality or performance.
  2. DxOMark Sensor is a logarithmic scale in which a 5-point increase corresponds to a sensitivity gain of 1/3 of a stop.
  3. DxOMark Sensor AND resolution: two metrics of sensor performance.

This interactive graph shows the ranking for the currently-available digital cameras on the DxOMark Sensor scale and its three metrics (click on the different tabs to view the performance and ranking of cameras versus each metric). You can switch the x-axis for time, price range, or resolution, as well as filter the ranking by brand, resolution, sensor size, time and price (USD). You can also access the comprehensive set of RAW-based measurement data, curves, and plots for any given camera by clicking on its product sheet (left column).
