Klaus, how do you account for the MTF numbers being *lower* on the edge on the 16MP sensor than they were on the 10MP sensor? (Sample variation?) On a related note, where was the copy you tested manufactured?



Thanks!

I do not know for sure. The 16mp sensor of the K5 is not much different than the 10mp sensor of the K10D.

The AA filter characteristic is very different though. The K10D AA filter has no vertical filtering at all so the border performance figures can be different if the sagittally or tangentially is emphasized.

The center resolution characteristic may be different due to the different RAW profile of the cameras although I am surprised about the difference.
