Compact digital camera purple fringing comparison
 |
To measure purple fringing caused
by lens chromatic aberrations and sensor blooming, we photographed a custom
test chart, left, with areas of very high contrast. We used the cameras
at their widest and longest focal lengths with the aperture wide open. The
crops are taken from the upper left corner of the chart and presented here
at 100%. A small amount of fringing is visible with all four cameras at both wide angle and telephoto settings. This is typical for most cameras, and none here are particularly better or worse than the others in this repsect. |

Compact digital camera macro comparison
| To measure macro performance we photographed a custom chart using the
bundled lenses at a distance and focal length which delivered the maximum
possible reproduction. The dark lines are 10mm apart. Here the Fujifilm and Sony models performed averagely, while the Pentax, unable to focus closer than 15cm, produced a below average result. The clear winner here is the Canon A620, which can focus as close as 1cm away from its subject, offering amazing potential for macro-photography. |
