Resolution Chart Comparison

Comparison cameras:

  • Canon PowerShot S60 (5 mp, 4x zoom)
  • Casio EXILIM EX-P600 (6 mp, 4x zoom)
  • Samsung Digimax V50 (5 mp, 3x zoom)
  • Sony DSC-F88 (5 mp, 3x 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 +1.3 EV.

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)

Not very surprising but the S60 delivers an identical resolution performance to the S50 before it, they share the same sensor and essential image processing and obviously are not limited by the lens (or any differences betwen the S60 and S50's lens). Compared to the other cameras here only the V50 gets close although it's dogged by some visible moire, especially and higher frequencies. Perhaps the biggest disappointment would be the Casio EX-P600 whose six megapixel CCD delivers very little more than the five megapixel S60.
