Resolution Chart Comparison

Comparison cameras:

  • Sony Cyber-shot DSC-H1 (5 MP, 12x zoom)
  • Canon PowerShot S2 IS (5 MP, 12x zoom)
  • Panasonic DMC-FZ5 (5 MP, 12 x zoom)
  • Kodak EasyShare DX7590 (5 MP, 10x zoom)
  • Konica Minolta DiMAGE Z5 (5 MP, 12x 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.

+ Chart maximum
Jagged diagonals
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)

There is very little between the top three cameras in this class; the Sony H1 and Panasonic FZ5 (and FZ20 for that matter) produce noticeably cleaner results than the Canon S2 IS, but in terms of absolute detail it's a close call, and none of them will disappoint. As with the other cameras in this class we found that diffraction effects mean resolution starts to drop off fairly quickly at apertures of F6.3 and smaller.
