Compact digital camera wide angle uniformity comparison
| To measure lens vignetting and light fall-off we photographed a white
target with a highly diffused custom filter. Here are the results for the
cameras at their widest focal lengths with the apertures wide open and the
focus manually set to infinity. The images were analysed with Imatest and
the full areas presented here at a reduced resolution. Bigger percentages
are better. The Fujifilm and Sony models performed best here with very little darkening in the corners of wide angle shots. The Canon A620 performed averagely in this respect, but again the Pentax S6 came last with noticeable darkening in its corners at wide angle. |

Compact digital camera telephoto uniformity comparison
| To measure lens vignetting and light fall-off we photographed a white
target with a highly diffused custom filter. Here are the results for the
cameras at their longest focal lengths with the apertures wide open and
the focus manually set to infinity. The images were analysed with Imatest
and the full areas presented here at a reduced resolution. Bigger percentages
are better. Zoomed-in to telephoto, the results were much closer, and also much improved for the Pentax S6. The Fujifilm F11 edged ahead once more, leaving the Canon A620 coming last, albeit not by a large margin. |
