Panasonic Lumix DMC-FX30 wide-angle geometry comparison
|
 |
|
To measure and compare the Panasonic Lumix FX30's
geometric distortion we photographed a test chart consisting of a grid pattern,
using it and a number of rival 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.
The image left was taken with the Panasonic Lumix FX30 zoomed-out to 4.6mm. |
4.6-16.4mm at 4.6mm
Distortion: 2.7% barrel |

| Barrel distortion was measured at 2.7% which is roughly the same as the Sony N2 and slightly worse than the Canon A640; all three are noticeably worse than the Fuji F30 which wins this round. In the FX30's defence though, it offers much wider coverage when zoomed-out than the other three models here, so greater geometric distortion is expected. |

4.6-16.4mm at 16.4mm
Distortion: 0.01% barrel |

| Pincushion distortion was measured at 0.01%, which is essentially close to a perfect score. The other three models below don't exactly have it bad in this respect, but the FX30 comfortably takes the lead. A very good result here for the FX30. |
