Resolution Chart Comparison

Comparison cameras:

  • Minolta DiMAGE A200 (8MP, 7x zoom)
  • Nikon Coolpix 8700 (8 MP, 10x zoom)
  • Olympus C-8080 WZ (8 MP, 5x zoom)
  • Konica Minolta DiMAGE A2 (8 MP, 7x zoom)
  • Sony DSC-F828 (8 MP, 7.1x zoom)
  • Canon PowerShot Pro 1 (8 MP, 7.1x 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, settings all factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +0.7 EV to +1.3 EV.

# Jagged diagonals
+ 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)

Unsurprisingly, the A200 produces a result very similar out of the camera JPEG to the A2, though the new processor does seem to be squeezing out a little more resolution (to be fair this may simply be the result of QC differences between our sample cameras - this is after all the same lens and CCD). Disappointingly the fine detail capture is still not that clean, with visible moire from about 1400 lines. To see how much of a resolution advantage shooting RAW offers, see the next page.
