Resolution charts

As part of our image quality testing for the Leica M9, we've shot our resolution chart with the Leica APO-Summicron-M 75mm f/2 ASPH 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 Leica is capable of resolving up to around 28 (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:
