At first when I picked up this baby, wow!...First impression this is very solid, worth every penny. Originally I had me eyes on the D100, but with the vertical grip and all. It weight almost as the D1x, so I had to consider the D1x. Weight is a concern, but with the shots I get, I forget about that usually. Every function is almost automatic and with little delay. I dropped it a couple times already by accident of course. Nothing, still ticking. But the 28-70 glass attached is in repair now. Come back home soon please. Reading and writing is awesome too. I tried 512mb media as Ridata, Sandisk, and Crucial. All seem to work well. Ridata give me a little bit probs ie, freezes my camera once in awhile. But very cheap and fast card for the most part. There is a bit of noise in long exposure and high iso. But can be dealt with using the proper software. I can go on and on but I won't bore you. In summary, awesome, awesome and awesome. Nikon might take a while to get new cameras out but when they do you got to love them.
By the way if you have any specific questions, you can email me personally or post here of course too. I know I didn't have a complete review of everything.
