Well I am waiting to test it ...I tested the 24 mp 3200 against the 7000 and the 7000 was slightly better ...Hogan is talking about the lens now being the limiting factor ....now you say use a prime but not for my work ..I need a 18-200 or better 300 Zoom and it seems that big zoom glass is not good enough to get the best from a 7100....
Still when I get my hands on one I will do a test with my trusty chart .my othere choice is a D800 and new glass but that is going to cost $5000 x2 so up the creek goes the profits and its only a 24-200 zoom so a backwards step ..crop and back to square one ....
Only time will tell ...Test dont Guess
2 7100. One with 17-55 2.8, other with 70-200 2.8 and keep one D700 as backup with 10-20 wide-angle. Less expensive, better quality because of better lenses. Mind you the 18-200 is OK, but once you will have worked with the 17-55 and 70-200, you will NEVER look back.
Of course this is only my personal opinion and in no way reflects Nikonites forum.
