Our results from the lab have been compared against the Nikon Coolpix S8200, Fujifilm F550 EXR and Olympus SH-21

Our analysis shows that the IXUS 125 HS produces similar results for both signal to noise ratio and dynamic range as the Nikon Coolpix S8200. Dynamic range results across the sensitivity range are good showing the detail in the shadows and highlights can still be captured all the way up to ISO 3200.

Noise is equally handled well with the results at ISO 3200 coming in just above 30, showing that whilst noise is present in the images it is possible to capture a decent picture with detail in low light conditions.

Resolution

As part of our image quality testing for the Canon IXUS 125 HS 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 IXUS 125 is capable of resolving up to around 22(line widths per picture height x100) in its highest quality JPEG files.

See a full explanation of what our resolution charts mean, and how to read them.

Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:
