D700 Noob here, I've managed to get the thing into some kind of weird mode where only 1 focus point is active in the center of the viewfinder. I've tried various options in the autofocus menu settings, such as the dynamic AF area setting 9, 21, 51, etc... (although I doubt that's the issue because I don't even see an option for 1 - but that's all I've got!) For a brief time it was a single active AF point in the upper left corner...but after reseting everthing I could find, it moved to the center.
What did I do? Up to now the only controls I've been experimenting with are ISO and exposure compensation. I thought I read that there is a feature where you specify a specific focus point to be active, but I can't find it in the manual.
It could be that way by default. Ever since I got my D3 back from Nikon it has been that way. It has been so long that I do not remember how I had it before. If against something with high contrast I can just barely see the grid.
You should be able to move the red square with the large shuttle button if it is unlocked.
I have my manual open in pdf where I can do a search. Why did you find the solution and what was it?
I was in single-point AF mode. There is a 3-position switch below the selector dial "AF Area Mode Selector", that controls that mode. I must have tweaked it somehow.
I really need to take a class or something on this beast. It is SO MUCH more complicated than my F4 was. Don't get me wrong... I love it! Being a gadget junkie, half the fun is tinkering with all of the settings. It's more fun than video games for me!
My wife's D3 is set up different from mine. I could save her settings to a flash card and transfer them. Instead I copied my back up settings from my computer and loaded those.
I did however forget that the default is single mode when they return a camera from Nikon Repair. I won't be using it much before this weekend's Event or I would have figured that out at the first burst of shots.
