Great images and also representative of the AF performance of my D800 under most conditions.

My only issue with the D800 focus is that AF-C tends to micro hunt when shooting under tungsten lights (typical lounge lighting), never settling on the subject. This would typically be an eye of a head and shoulders subject. My D3S never did that.

I'm currently working on posting some test images to show this using a photograph of a portrait as the focus target (flat target). Sequential images show slight variations in focus accuracy from shot to shot, depending at what point in its continuous micro hunting the AF-C focus is stopped at to take the photo.

Have you experienced anything similar? No point in sending my camera in to Nikon if this is a limitation of the AF-C performance generally.

i just sent a d800 back because of the same problem. Lounge light makes it really hunt for focus a lot in AFC. A friend of mine has a d800E and is experiencing the same problem. Sure i can use live view to get the best shots, but i also like to take candids of children in lounge light using AFC. too much to ask?

Why use AF-C if the models don't move? ...and if they move then the AF should follow them. If the AF is hunting perhaps they (or you) are moving a bit. If not then you should reduce the sensitivity setting.
