To test the Fuji F550 EXR image quality, we shot our resolution chart with the F550 EXR's Fujinon 15x optical zoom 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 Fuji F550 EXR is capable of resolving up to nearly 14 (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:
Each image was shot at f/5.2
