Resolution Chart Comparison

Comparison cameras:

  • Samsung Digimax Pro815 (8 MP, 15x zoom)
  • Fujifilm FinePix S9000 / 9500 (9MP, 10.7x)
  • Konica Minolta DiMAGE A200 (8MP, 7x zoom)
  • Nikon Coolpix 8700 (8 MP, 10x zoom)
  • Kodak EasyShare P-880 (8 MP, 5.8x zoom)
  • Panasonic Lumix DMC-FZ30 (8MP, 12x 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). For each camera the relevant prime lens was used. 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 +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 Pro815 is producing resolution broadly similar to most of last year's 8 megapixel models, but is nowhere near the top of the pack, with the Panasonic FZ30 and Fujifilm S9000 firmly trouncing it. The fact that you can get considerably more resolution by shooting Raw points the finger of blame firmly at the in-camera processing, which is a pity as this is obviously a very capable lens.
