By the way, a 12Mp D3, can't possibly compete with a 12Mp D300S when cropping to the same magnification.

PPD, pixels per duck! Think about it... Simple maths. Brick size pixels.


That's not true Robert, despite your maths.

I struggled over far too many experiments with the D3 and the D300 (notS) trying to decide if there was any difference in image quality cropping a D3 to D300 frame. Inconclusive at best. The only image benefits come from not emphasising noise by cropping. So in poor light the D3's better handing of noise ( 1-2stops ) meant cropping never emphasised the noise as much as the DX performance at the same ISO.

In good light there was no difference.
