As part of our image quality testing for the Olympus OM-D E-M5 , we've shot our resolution chart with a Sigma 50mm f/1.4 EX DG HSM lens mounted. 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 200 the Olympus OM-D E-M5 is capable of resolving up to around 24 (line widths per picture height x100) in its highest quality JPEG files.
