DiMAGE Z1 |

Technical Information: Camera


There are chromatic aberation/purple frightning in the images. |

Chromatic aberration may occur on an image in a few cases and is usually visible in very bright areas of the picture as a coloured fringe. Chromatic aberration is generated by the different wavelengths the light consists of. For every wavelength there is a different focal point.

The lens cannot focus the different wavelengths on one single focal point only. This is due to the refractive index of the lens. Short wavelengths (blue light) have a higher refraction index than long wavelengths (red light). The extent of the chromatic aberration results from the dispersion of the (lens) glass.

In particular compact cameras featuring a long zoom range are affected. The lens system of the DiMAGEZ1 is sophisticated and is one of the best in its class in comparison. Chromatic aberration can be minimized by screening off.

On the Konica Minolta Photoworld (online) you find explanations and tips which help to lessen chromatic aberration.
