Pentax 645D vs D800 Image Quality

Bigger viewfinder, shallower DOF, higher resolution, more crop factor, bigger prints, plus the 16bit images & ISO 50 will all show the sensor is a champion on DxO.

The IQ on the 645d is still better as you mention, but the FX D800 is a step up from APS-C, and it's the first time this has happened in a few years really.

I will happily take the Pentax fullframe equiv to the D800/e for the same price.
