Re: What happened to the Nyquist Frequency?

Getting right to the point, a FF version of the 7D sensor would be 46 MP. So, however well FF lenses fare on the 7D is how well they'd fare on a 46 MP FF sensor.

DPR used to show lens reviews with the Nyquist Frequency marked and sited the 1DsIII as the sensor resolving benchmark; from memory many lenses only out-resolved it in the centre. Moving to 36MP I can see only a few lenses hitting that mark in the very sweetest of spots.

Every single lens tested on PZ, everywhere (even the 17-40 wide open in the corners, as far as I remember) shows improvement from 8mp crop (the 1Ds3 pixel density) to 15mp (about 33 mp on FF). This improvement is about 20-30% in the PZ metric.
