I'd like to better understand the issues that you guys are having. I just got my d800 last week and most of my initial shots with it have been indoors, in low light tungsten, high ISO stuff. I'm not seeing anything unusual with the AF, but I'm not seeing the claimed "improved low light" AF over my d3s or d300. But, I'm not shooting at any significant distance, usually within 10 feet or so.
So, what lenses are you using, at what distances? You say medium to far distances, but I don't understand what you mean by that. Are you using the cross hair sensors, fast glass, maybe 24-70 or 28-70? Are you then viewing at 100% to determine focus accuracy?
In the past, I've had problems with other cameras in low light conditions, trying to AF on the eyes, but if the subject is too far away and the AF sensor isn't confined specifically to the eye area with enough contrast, then AF accuracy goes way down.
So, if you can give me more detailed info, I'd like to try to duplicate your experiences. I have many of the typical pro level lenses that would be used for portrait, weddings, ie 85 f/1.4, 105 and 135 f/2 DC, 50 f/1.4, 28-70 and 24-70. Let me know if one of those lenses is part of your issue and I'll use the ones you indicate.
thanks

Yes friend thank you, but yea to be more specific is this at dim lights say like reception or church the camera has about 25% percent accuracy, I literally have to shoot like 10 times same pose or whatever to make sure at least one photo is in focus and even there it is still no 100 % right. No amount of AF tuning could really help. When there is plenty lights and my subject has good contrast the D800 nails the focus but I shoot like 80% in challenging light conditions and the D800 is horrible at a medium to far distances, up close is good like your subject is almost filling the frame but at far distances it is trouble. I shoot with primes at F 1.4 through F2 and anything at these setting looks just messy, I can not trust the D800 at all in dim lights it is hit or miss but more like miss and glad I bring with me the D3s it is def better. I have been doing photography since I was 17 years old, I am 36 now and I believe I have some good sense as to what I am doing so no it is not me or my poor techniques, it is the camera so if some of you claim not having this problem you are either ignorant, too afraid to admit it or simply have not shot with your d800 in the poor lighting conditions.

I like my D800 and like you I get wonderful results in the studio and wherever there is daylight available.
In incandescent light, the AF is off more than +20 and cannot be fine tuned. So all my lenses front focus and there is nothing sharp in the picture when light is yellowish. Blue is no problem. I photograph rehearsals on a regular basis and the AF is spot on in near darkness with some blue spots.
