Resolution Chart Comparison

Comparison cameras:

  • Panasonic DMC-FX01 (6MP, 3.6x zoom)
  • Fujifilm FinePix F10 (6 MP, 3x zoom)
  • Canon PowerShot SD630 / Ixus 65 (6 MP, 3x zoom)
  • Hewlett-Packard R727 (7 MP, 3x 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.

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)

Whereas the FX9 boasted near class-leading resolution, the FX01 is only just above the average for the class, though it's still very good, and the results are very clean, with little evidence of moiré except at the very highest frequencies. There are none of the excessive processing (particularly sharpening) artefacts seen on certain other Panasonic images. That the lens is good is obvious, though it's also obvious that it can't capture quite the same level of detail as the 3x zoom on its predecessor.
