 | 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. |

 | 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. | |
|
7.9-23.7mm at 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. |
