Resolution Chart Comparison

Comparison cameras:

  • Nikon Coolpix 8400 (8 MP, 3.5x zoom)
  • Nikon Coolpix 8800 (8 MP, 10x zoom)
  • Olympus C-8080 Wide Zoom (8 MP, 5x zoom)
  • Konica Minolta DiMAGE A2 (8 MP, 10x zoom)

Shots here are of the PIMA/ISO 12233 standard resolution test chart (more of which are available in our comparison database). This resolution chart allows us to measure the actual performance of the lens and sensor system. It measures the ability of the camera to resolve lines at gradually higher resolutions and enables us to provide a definitive value for comparison purposes. Values on the chart are 1/100th lines per picture height. Thus a value of 15 equates to 1500 lines per picture height.

Studio light, cameras set to auto, all settings factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +0.7 EV to +1.0 EV.

+ Chart maximum
LPH Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)
5° Diagonal Lines set at 5° diagonal
Absolute res. Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency).
Extinction res. Detail beyond camera's definition (becomes aliased)
n/a Not Available (above the capability of the test chart)
n/v Not Visible (not visible on test results)

The essential jist of the results from our resolution chart is that the 8400 and 8800 are both an improvement on the 8700 (but only slightly) and that the C-8080 still exhibits the best eight megapixel resolution. Interesting to see the G6 perfoms so well only really loosing out on extinction resolution.
