As part of our review process we've implemented a new testing procedure. To test the Canon EOS 60D image quality, we shot our resolution chart, each with the Sigma 50mm f/1.4 EX DG HSM lens.

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 60D is capable of resolving up to 26 (line widths per picture height x100) in its highest quality JPEG files. Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
