Panasonic Lumix DMC-FS22 review: TechRadar labs data
Resolution charts, noise and dynamic range graphs
Our test of the Panasonic Lumix DMC-FS22 is on the way, but in the mean time we would like to share the resolution chart images and the noise and dynamic range results.
Panasonic launched the Lumix FS22 in May, it features a touchscreen, 4x optical zoom and a 16.1 megapixel sensor.
Lab results from the camera show that its signal to noise ratio scores are on par with the Nikon Coolpix S4150, Samsung PL170 and Canon IXUS 310 HS. The noise results show that whilst noise does start to become apparent at ISO 800 images are still usable. Dynamic range results are good throughout the sensitivity range showing only a slight drop between ISO 100 and 1600, this means that even at higher sensitivity settings the camera is still capible of capturing a good amount of shadow and highlight detail.
The Panasonic Lumix FS22 is available to buy now, with prices around £150.
Resolution charts
As part of our image quality testing for the Panasonic Lumix DMC-FS22, 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 Lumix DMC-FS22 is capable of resolving up to around 24 (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:

Noise and dynamic range
These graphs were produced using data generated by DXO Analyzer.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Panasonic Lumix DMC-FS22 are on a par with those from the Nikon Coolpix S4150 and Canon IXUS 310 HS, showing consistent results throughout the sensitivity range.

Dynamic range
This chart indicates that the Panasonic Lumix DMC-FS22's JPEGs produce good results for dynamic range across the sensitivity range, beating both the Samsung PL170 and Nikon Coolpix S4150.
