Here we will use our standard color and resolution charts to compare the Fujifilm FinePix S7000, Sony DSC-F828, Minolta DiMAGE A1 and Canon PowerShot G5.

Color Chart Comparison

Color charts are shot in daylight, Auto White Balance, +0.3 EV exposure compensation (except the DSC-F828 which required +0.7 EV exposure compensation to achieve the same tone balance). All cameras are given 20 seconds for their white balance systems to settle before the shot is taken (often we will take up to eight shots and select the 'average' AWB result).

In the table below we're only measuring color. The RGB values were measured from a VGA reduced image (to average colors, remove noise and eliminate JPEG artifacts) using the Eyedropper tool in Photoshop with a 5 by 5 Average Sample Size.

Here you can see that there is an imbalance in the S7000's color response, specifically it responds more strongly to reds (the red and magenta patch show this) than it does to blue or green. Also note that the cyan patch has too much green and not enough blue leaving it looking a little 'muddy'. In some samples we took this led to the red channel clipping (reaching 255) earlier than we would expect.

Resolution Comparison

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. So a value of 8 equates to 800 lines per picture height.

Studio light, cameras set to auto, all settings factory default. Exposure compensation +0.7 EV for all cameras (to compensate for the white background). Click on the camera name below the crops to download the full resolution chart (large JPEG's).

Definition of terms

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 Resolution Still defined detail (below Nyquist frequency*)
Extinction Resolution Detail beyond camera's definition (becomes a solid gray alias)
n/a Not Available (above the capability of the test chart)
n/v Not Visible (not visible on test results)

* Nyquist frequency defined as the highest spatial frequency where the CCD can still faithfully record
image detail. Beyond the Nyquist frequency aliasing occurs.

Compared to the other cameras the S7000 actually fairs quite well with more resolution than most five megapixel digital cameras at the 6 MP setting. Switching up to the 12 megapixel image size does appear to deliver more resolution.
