Guy, You mean when the D800 whips the IQ 160 in all image characteristics, we can expect a "distressed" fire sale on your IQ 160 and all associated equipment? (Time & Date Please :ROTFLNo question I will put it up against a gold standard like the Iq 160 back and see how it measures up outside the resolution side. On the resolution side we have to see what are good sharpening setting that give a nice neutral file and look. People tend to push this area too hard. Finally we have to see how it prints at native size and larger.
But seriously, I think the more we learn and work with the D800 files and understand both their pluses and minuses, their malleability with regards to various and extensive post processing and certainly the cameras body's capabilities, will certainly go a long way as to their value in providing an appropriate substitute for other systems we have in our arsenal for certain applications. It's a bit too early to tell, but so far I've been impressed with various (although no all) aspects of it's files.
