Just picked up my D800 today.
There have been some reported AF issues with the outer left or right AF sensors, especially with large aperture lenses like f1.4 and the like, but it seems as though the AF works perfectly so far. Even used it on my 85mm f1.4G and every shot was spot on focus using either a left or a right or a middle focus point. Happy with this.
There does seem to be a very slight green tinge to the rear LCD, but I am actually thinking this is an auto WB issue as the photos did need a tad bit of WB correction. I will have to investigate this further. Maybe a firmware upgrade to fix this very minor issue (if it is indeed an issue).
First thing I noticed was that you can feel that it is much lighter than the D700, yet with the same solid feel like the D700. Happy with this.
Shutter noise is more subdued than the D700, more like the D7000 but with extra damping. Happy with this.
AF does seem faster and more precise as I didn't have any misfocus issues that could be attributed to the camera. This is great news especially under the adverse conditions. Very happy with this so far.
Here are a few shots. I normally use Capture One Pro to convert my RAW images, but as they do not have the RAW file for the D800, I decided to convert them to TIFF through NX2 (I don't like NX2 workflow) so please bear with me as these are quick conversions to show the capabilities of the camera.
These were taken at Sydney's Taronga Zoo on possibly the worst day of the year as it has been pelting down with rain most of the day and been very gloomy and dull. Still, it doesn't put off someone with a new toy to test.
Many were taken at ISO6400, noise reduction has been used on some images (Noiseware Professional) some were taken with the 300 f2.8 VRII (first pic with 2x TCIII), some with the 85mm f1.4G and some with the 70-200 f2.8 VRII, but EXIF is included for your information. Most are shown for their high ISO results and crops of them for closer scrutiny.
