Resolution Chart Comparison

Comparison cameras:

  • Fujifilm FinePix S100FS (11.1 MP, 2/3" sensor, 14.3x zoom)
  • Olympus E510 (10 MP, 4/3 sensor)
  • FujiFilm S8100fd (10 MP, 1/2.3" sensor, 18x zoom)
  • FujiFilm FinePix S6000fd (6.1 MP, 10x zoom)

Shots here are of our standard resolution chart (version 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 ontally flipped but are otherwise identical). For each camera the zoom was set just in from wide angle, where it is likely to perform at its best. The chart is shot at a full range of apertures and the sharpest image selected.

Studio light, cameras set to auto, settings all factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +1.0 EV to +1.7 EV.

Resolution tests charts are an area in which the Super CCD technology traditionally performs very well and the S100FS lives up to that expectation. The FujiFilm S8100fd, which does not use a the Super CCD technology, shows that resolution can't be sensibly measured by the number of photosites a sensor has. The Olympus and FujiFilm S8100fd are both 10 megapixel cameras but there is a major difference in terms of how much detail they can actually resolve.

The comparison with the Olympus E510 (with noise filtering off), shows just how well the S100FS is doing though, as we've already seen, this is partly because high contrast black and white test charts are one of Super CCD's party tricks (and to be fair because the lens has excellent resolving power). You won't always see the benefit of this resolving power in your images, unless you are particularly keen on shooting res-charts.
