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.

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. |
