Sony Cybershot N2 wide-angle geometry comparison
|
 |
|
To measure and compare the Sony Cyber-shot N2'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 Sony Cyber-shot N2 zoomed-out to 7.9mm. |
7.9-23.7mm at 7.9mm
Distortion: 2.72% barrel |
| |
| Barrel distortion was measured at 2.72% which is the worst of the four cameras tested here, although to be fair, close to the Canon A640 result. |

Sony Cybershot N2 telephoto geometry comparison
 |
|
To measure and compare the Sony Cyber-shot N2'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
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.
The image left was taken with the Sony Cyber-shot N2 zoomed-in to 23.7mm. |

Distortion: 0.38% pincushion |
| |
| Pincushion distortion was measured at 0.38%, which is again the worst of the group, although again close to the result from the Canon A640. |
