I have had the D200 for a 10 days. I also have a D2x which I have been contemplating selling and purchasing a second D 200. I am not a pro but I do all types of photography. For the past 3 days I have been shooting birds in flight at the desert Museum in Tucson Az. I do find the D200 does not track and lock in focus birds in flight as well as the D2x. I get a higher percent of keepers with the D2x. Last week I was shooting butterflys in an enclosed structure. I had about the same percent of keepers as I would get with the
D2x. I am going out to shoot hummingbirds tomarrow.
My initial reaction is that for my type of photography the D 200 would do just as good a job as the D2x with the exception of focus tracking fast moving objects.
The only other issue is the battery. The D2x goes on and on. I have never had to change a battery during the day with the D2x. I do not look at this as a disadvanted to the D200. I just think the D200 will require 1 or 2 extra batterys.
I would be interested in hearing from others that have been thinking of selling a D2x and going with a couple D 200's
