Mine was delivered today. Build quality is excellent, with one slight nit to pick. The circular selector switch on the back looks a bit less stout than on the D7000. Maybe it will work out, but it looks a bit fragile.
I took it out for an hour after work to check it out and am suitably impressed. I took a tripod mounted series and ran the same shot from ISO 100 THROUGH 6400. I will take a close look after dinner and will post some samples for review later this evening.
This camera looks like a big winner for Nikon. And me.
