As part of our image quality testing for the Canon EOS 5D MK III 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 5D MK III is capable of resolving up to around 28 (line widths per picture height x100) in its highest quality JPEG files.

See a full explanation of what our resolution charts mean, and how to read them.

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