Resolution Chart Comparison

Comparison cameras:

  • Konica Minolta DiMAGE Z2 (4.0 MP, 10x zoom)
  • Panasonic DMC-FZ10 (4 MP, 12x zoom)
  • Canon PowerShot S1 IS (3.2 MP, 10x zoom)
  • Fuji FinePix S5000 Zoom (3.1 MP, 10x zoom)*

*the FinePix S5000 has a 3.1 MP effective SuperCCD chip that outputs 6MP images - these measurements were taken in 6MP 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.

Extinction res. Detail beyond camera's definition (becomes aliased)

In sheer resolution terms the Z2 is surprisingly good - certainly better than might have been expected from such a keenly-priced camera with a full 10x optical zoom. The chart clearly shows the superior resolving power of the Panasonic FZ-10, but there is not as much difference as we might have expected. The lack of sharpness (as opposed to resolving ability) is obvious, and was borne out in all our real-life test shots, which tended to look at touch soft straight out of the camera - down to the very gentle in-camera sharpening. The generally clean images (at lower ISO's) lend themselves well to a little sharpening in Photoshop. The only fly in the ointment is the strong moire patterns, which start at quite modest frequencies.
