Stan, I think you made some valid and intelligent points, especially that the current camera equipment is quite good including the DX Nikon D7000. One looks a picture with their eyes not lab equipment. As you put it, the cost/performance ratio is extremely high on the D800. Agreed.
Just to add my perspective, that may be the same as yours, great glass fundamental to reaching the optimal quality level on the D800. I have always been a believer in the highest quality lenses starting with the Nikon 105mm/ 2.5 many decades ago. This has been a successful path for me.
I am not a pro, rather simply a man who enjoys photography as a hobby. As for me, I am waiting to get my hands on the D800 and read Nikonian reviews before a purchase. There is inconsequential doubt in my mind that I will ultimately wind up with the D800, but I want to do it my way. In South Florida (Palm Beach, Ft. Lauderdale and Miami) there is a waiting list virtually everywhere. Quite extraordinary. This camera is a hot ticket item.
