Panasonic TZ20 Review: Image quality and resolution
As part of our image quality testing for the Panasonic TZ20, 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 Panasonic TZ20 is capable of resolving up to around 20 (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:
ISO 100 – 20 View the full-size image
ISO 200 – 20 View the full-size image
ISO 400 – 18 View the full-size version
ISO 800 – 14 View the full-size image
ISO 1600 – 14 View the full-size image
