I’ve now shot a few commercial jobs and a wedding with the D800. Overall I’m very pleased with it. The amazing resolution is showing the limitations of the glass more than anything, particularly if you need to go beyond f16. It’s still not perfect, though some quirks may be operator error. I’ve experienced the lockup issue which is supposedly fixed by the firmware update I haven’t applied yet. I’m hoping the next update will address the green cast in the monitor. It’s annoying, especially compared to my trusty D300. Sometimes I’m in yucky mixed lighting situations – a little fluorescent, a little tungsten and (don’t ask) a little daylight. I could at least give a semi-reasonable guess looking at the D300 monitor. The D800’s green cast makes manual adjustment pure Kentucky windage and its odd auto white balance at times makes it a pure post thing. I haven’t tested the left focus yet and haven’t noticed it, but I have had some odd focus at times in the actual images. Hopefully it’ll all get straightened out in time, it’s still a fine machine.
