Resolution Chart Comparison
Comparison cameras:
- Kodak EasyShare Z740 (5 MP, 10x zoom)
- Sony Cyber-shot DSC-H1 (5 MP, 12x zoom)
- Canon PowerShot S2 IS (5 MP, 12x zoom)
- Panasonic DMC-FZ5 (5 MP, 12 x zoom)
- Kodak EasyShare 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.

There's not a massive difference in the resolution of all the current crop of 10x zoom cameras, and the Z740 manages to keep up fairly well with its higher-profile competitors, though (along with the DX7590) it doesn't quite make the first division. If you download and look at the chart you'll see the slight corner softness - and the effects of fairly harsh in-camera sharpening on what are really quite soft images. |
