Resolution Chart Comparison - at 12MP

Comparison cameras:

  • Fujifilm FinePix E550 (12 MP, 4x zoom)*
  • Minolta DiMAGE A2 (8 MP, 7.1 zoom)
  • Sony DSC-P150 (7 MP, 3x zoom)
  • Canon PowerShot G6 (7 MP, 3.5x zoom)

*the FinePix E550 has a 6.1 MP effective SuperCCD chip that outputs 12MP images - these measurements were taken in 12MP mode.

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.

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 E550 shows just how much detail this lens/sensor combination can capture at the 12MP setting - outperforming cameras costing much, much more. Our tests also confirmed that the E550 produces identical results to the F810. If you want detail - and clean detail at that - the E550 offers a remarkably low cost way to get it.
