As part of our image quality testing for the Ricoh GR IV 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 GR IV is capable of resolving up to around 20 (line widths per picture height x100) in its highest quality JPEG files.
