As part of our image quality testing for the Canon 1DX, we've shot our resolution chart.

If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 100 the Canon EOS 1DX is capable of resolving up to around 26 (line widths per picture height x100) in its highest quality JPEG files.

For a full explanation of what our resolution charts mean, and how to read them, check out our full explanation of our camera testing resolution charts.

Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
