Resolution Chart Comparison
Comparison cameras:
- Panasonic DMC-FZ5 (5 MP, 12x zoom)
- Panasonic DMC-FZ20 (5 MP, 12x zoom)
- Kodak DX7590 (5 MP, 10x zoom)
- Konica Minolta DiMAGE Z5 (5 MP, 12x 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) |
Very clean images with plenty of resolution - and surprisingly, easily as good as the more expensive DMC-FZ20. The Venus II processor has ensured virtually no artefacts are visible, and the Leica lens is obviously doing its job. Very good results indeed.
