Footage in this clip has not been edited, it is posted here to demonstrate what the new Nikon FX 36Mpx sensor does when it is left stark naked, filterless.
Nikon D800E is definitely a head-scratching option for anyone looking to upgrade from their bog-standard HDSLR (content looks so similar from all of them lately)
D800E behaves well when all consumer-type enhancements are turned off (D-lighting, auto-lens correction, vigneting correction, noise correction).
Write speeds are a bit slack with uncompressed RAW(NEF) written in 12 seconds to a 90Mb/s Sandisk - file size apx 75Mb - this indicates usage of earlier CF card slots instead of designing something that would allow faster writing (like XQD card slots on D4X). Same happens with SD card slot, as slow as CF.
RAW files are of 7424x4924 size and provide good texture to work with. Ok, slight understatement here, they are amazing. Sharpness is natural and light is perceived without being diluted by low pass filters, much like good old Phase One digital backs, or Hasselblad H4D - without the 20k pricetag.
If one likes to shoot JPG or HDR, you can get the same picture size but in a 16-38Mb file - yes compression is visible. HDR files produced present digital artifacts, but sensor makes up for it so results are suitable for A3+ or larger prints.
Built-in Timelapse mode creates a .mov file at 1080p/24fps (can be altered), footage is usable at consumer level so if you want real interval shoting you can set the beast to shoot RAW at given intervals.
Video section gives us manual audio controls, the usual fps selection and that is that really. HDMI out does 720p or 1080i, so an external recorder wouldn't capture 1080p, unless a firmware update might allow that at a later stage.
My conclusion is that we're not looking at a 5D mkIII deal breaker, those users are addicted for life. I can see digital back people going for D800E as a street camera, since it replicates the texture and depth of medium format sensors in a much more portable body.
