Resolution Chart Comparison

Comparison cameras:

  • Canon Powershot SX100 IS (8MP, 10 x zoom)
  • Panasonic Lumix DMC-TZ3 (7.1MP, 10x zoom)
  • Sony Cybershot DSC-H3 (8MP, 10x zoom)
  • Fujifilm Finepix S8000fd (8MP, 18x zoom)

Shots here are of our standard resolution chart (version one or two). This 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. So a value of 15 equates to 1500 lines per picture height. (Note that on version two of our chart the vertical resolution 1000 - 2000 lines have been horizontally flipped but are otherwise identical).

Studio light, cameras set to auto, settings all factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +0.3 EV to +1.3 EV.

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 SX100 IS' resolution is very good for a 8MP camera, it is amongst the top performers in its class. Image output is not extremely sharp but clean from artefacts. There is very little moire at higher frequencies and a few jagged lines, although this isn't anything you would ever recognize outside the world of test charts.
