Panasonic Lumix DMC-FZ8 wide-angle geometry comparison
|
 |
|
To measure and compare the Panasonic Lumix FZ8's
geometric distortion we photographed a test chart consisting of a grid pattern,
using it and a number of rival super-zoom models.
Here are the results for each camera with their built-in lenses at their
widest focal length; where possible, the aperture was closed.
The images were analysed with Imatest using 5th Order line calculation and
the full areas presented here at a reduced resolution.

6-72mm at 6mm
Distortion: 2.52% barrel |
| |
| The image above was taken with the Panasonic Lumix FZ8 zoomed-out to 6mm.
Barrel distortion was measured at 2.52% which is measurably lower than the Olympus SP-550UZ and Sony H9. The real star here though is the TZ3 compact, which exhibits remarkably low geometric distortion when zoomed-out - even more impressive when you consider it's then working at an equivalent focal length of 28mm, compared to the FZ8's 36mm. |

Panasonic Lumix DMC-FZ8 telephoto geometry comparison
 |
|
To measure and compare the Panasonic Lumix FZ8's
geometric distortion we photographed a test chart consisting of a grid pattern,
using it and a number of rival super-zoom models.
Here are the results for each camera with their built-in lenses at their
longest focal length; where possible, the aperture was closed.
The images were analysed with Imatest using 5th Order line calculation and
the full areas presented here at a reduced resolution.

6-72mm at 72mm
Distortion: 0.02% barrel |
| |
The image above was taken with the Panasonic Lumix FZ8 zoomed-into 72mm. Barrel distortion was measured at 0.02% which may be in the opposite direction to the other three cameras here, but in terms of overall geometric distortion, is the lowest and best result. Panasonic's own TZ3 also does very well here, with both cameras delivering very low geometric distortion compared to their rivals. |
