Panasonic DMC-FZ30 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 length
with an aperture of f8 in Aperture Priority mode. The images were analysed
with Imatest using 5th Order line calculation and the full areas presented
here at a reduced resolution. The image left was taken with the Panasonic FZ30 at 7.4mm f8 (equivalent to 35mm). Barrel distortion was measured at 2.35% which while better than the Canon kit lens, is comparable to the other all-in-ones. |

Panasonic DMC-FZ30 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 length
with an aperture of f8 in Aperture Priority mode. The images were analysed
with Imatest using 5th Order line calculation and the full areas presented
here at a reduced resolution. The image left was taken with the Panasonic FZ30 at 88.8mm f8 (equivalent to 420mm). Barrel distortion was measured at 0.317% which is similar to the Canon and Fujifilm results, although here the Sony R1 is the comfortable leader. |
