DxOMark in-depth measurements

Learn how DxO Labs tests camera sensors and lenses and how the DxOMark scientific measurements and protocols are defined.

DxOMark measurements for lenses and camera sensors

We measure the performance of camera sensors that are capable of producing RAW images, be it in professional, semi-professional or consumer-level categories. We also measure the performance of interchangeable lenses for cameras equipped with such sensors.

Measuring sensors using RAW and testing lenses on cameras

DxOMark has many unique features, two of which are that (1) we perform sensor measurements on RAW images and (2) we test each lens on every camera on which it can be mounted. Why do we do this?

DxOMark image quality testing protocols for lenses and sensors

A detailed look at DxOMark's image quality testing protocols, including laboratory conditions and setup, methods, test-specific tools, and software that DxO Labs developed and uses to ensure scientific, bias-free data and repeatable results.
