Why you can trust TechRadar
As part of our image quality testing for the Panasonic DMC TZ-30, 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 TZ-30 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, score: 20 (Click here to see the full resolution image)
