As part of our review process we've implemented a new testing procedure. To test the Olympus XZ-1 image quality, we shot our resolution chart.

If you look at our 100% crops below or download the images and view the central section at 100% (or Actual Pixels) you will see that, at ISO 100 the Olympus XZ-1 is capable of resolving up to 22 (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:
