Allen,
I don't think any D800e models have been delivered? Mine has the aa filter. One interest I had was video, and from what little I can read, not having the aa filter would not be good for video.
The professional I was referring to had gotten a D800, had not unboxed it, and asked to shoot mine to test whether he might be satisfied with the D800 -- he also shoots a Hasselblad 50 mp. After testing with mine, he elected to keep and start shooting with what had already been delivered. I think he will shoot less and less with the Hasselblad based upon his initial comments re the D800, and might even sell it. I think that says a lot about what he thinks of it.
He and other pros he has shared with are extremely impressed with the photos shot with mine, and its pairing with the Nikkor 14-24mm f2.8 lens I have to use on it. I am likewise very impressed with the photos shot (at this point only in full 2x3 format RAW) and also with video shot through that lens inside with available light. I need to test video outside in full daylight and other lenses, but even inside, the still frames extracted from the video is quite good.
The Pro discussion (I don't consider myself a pro) relative to comparison to medium format appears to center around diffraction at higher f stops, and it is not clear whether the "e" model would lessen this concern.
If you send me an email, I can share some test stuff with you. My email can be found by clicking on my name to the left, and looking in the bio line of the resulting Profile.
The file sizes are very large, and not evey configuration will love them.
Ernie
