Resolution Chart Comparison
Comparison cameras:
- Canon PowerShot S80 (8MP, 3.6x zoom)
- FinePix F10 Zoom (6 MP, 3 x zoom)
- Panasonic DMC-LX1 (8MP, 4x zoom)
- Kodak P-880 (8 MP, 5.8x zoom)
- Olympus Stylus 800 / Mju 800 Digital (8 MP, 3x zoom)
- Canon PowerShot S70 (7MP, 3.6x zoom)
Shots here are of our standard resolution chart (version one or two). This 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. So a value of 15 equates to 1500 lines per picture height. (Note that on version two of our chart the vertical resolution 1000 - 2000 lines have been horizontally flipped but are otherwise identical). For each camera the relevant prime lens was used. The chart is shot at a full range of apertures and the sharpest image selected.
Studio light, cameras set to auto, settings all factory default. If possible aperture was selected for optimum sharpness. Exposure compensation +0.3 EV to +1.3 EV.

Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency). |

Unsurprisingly the S80 manages a small increase in resolution over its 7MP predecessor, with a fairly clean artefact-free result. Interestingly both the Olympus Stylus 800 and Fujifilm FinePix F10 manage to outresolve it, but only by a smidgeon. |
