Luminous Landscape have posted an optical analysis of the 8-megapixel Sony DSC-F828 using the new optical testing system DxO Analyzer.

“One of the chief criticisms that has been aimed at the Sony F828 is with regard to chromatic aberrations. When I first prepared the graphs above I was therefore surprised to see how low the CA numbers were. They seemed unusually low. Then I looked at the data for other focal lengths.

The chart above and the table below help us to understand why some people sometimes see it and some people sometimes don’t.

This camera system - the sensor and lens combined - clearly displays considerable CA at wide angle settings, and lower but still quite high CA values at the longest focal lengths. But at mid-focal lengths chromatic aberration because very low, almost negligible.”
