DxOMark Camera Sensor is a raw benchmark for camera bodies by DxO Labs. The benchmark is “raw” because it measures image quality using Raw output files. It is also raw as DxO’s data can be used to cook up camera reviews that cover more aspects than image quality.
If you only want to compare a few specific cameras, the original data on DxOMark’s website should be perfectly adequate – although I still suggest browsing all the pictures in this article. However, if you want a deeper understanding of what the DxOMark scores really mean, if you care about tradeoffs in camera design or are wondering about major industry trends like “mirrorless” and small high quality cameras, this article might be of some use.
This article hopes to bridge the gap between scientific publications about camera sensor design (which are quite inaccessible for photographers) and consumer-oriented camera reviews. I have tried to maintain some degree of readability by including lots of diagrams, by mentioning examples, by moving details to endnotes and by adding some actual sample photos.
