Compact digital camera wide angle geometry comparison
| To measure geometric distortion we photographed a custom test chart consisting
of a grid pattern with perfectly straight lines. Here are the results for
the cameras at their widest focal lengths. The images were analysed with
Imatest using 5th Order line calculation and the full areas presented here
at a reduced resolution. The Canon, Pentax and Sony cameras performed roughly the same, exhibiting a typical degree of geometric distortion at wide angle. The Fujifilm F11 boasted an above average result here. |

Compact digital camera telephoto geometry comparison
| To measure geometric distortion we photographed a custom test chart consisting
of a grid pattern with perfectly straight lines. Here are the results for
the cameras at their longest focal lengths. The images were analysed with
Imatest using 5th Order line calculation and the full areas presented here
at a reduced resolution. Zoomed-in to telephoto, the Canon and Sony models again exhibited average distortion, although the Pentax S6 was measurably worse in this respect. Once again though, the Fujifilm F11 took the lead. |
