Also, can someone explain - Joakim/TheSuede perhaps - why NIkon left the complete optical filter pack in place with the D800E but simply used them to alter the light rays differently versus an AA filter INSTEAD of just completely removing them entirely? What\'s the benefit of breaking the incoming light rays into two and then reassembling them into one if no moire reducing occurs in the D800E filter pack? Would it not have been \"cleaner\" to just completely remove the optical filters (besides the IR) in the D800E?
I\'m neither of them, but doing what they did is a clever way to keep the optical paths between the two cameras identical in every respect except for the AA behavior. At a minimum they would probably have had to replace the AA filter with a piece of glass of very similar optical characteristics or changed the sensor distance. As they\'ve done it now from a manufacturing perspective the cameras are identical with a single part substitution and all the same calibration equipment can be used.
Yeah, cost/ production is the only benefit I see as well but I\'m really curious to hear more expert opinions.
Anyway, I too am idly curious as to exactly why they chose this approach over others.
