I think what the OP is talking about is not this at all.My guess is the OP has the menu option a4: AF Activation set to AF-ON only. If this is the case, then pictures can be taken when no focus confirmation dot has been ever acquired.No one knows for sure but it's believed this is a bug because it differs from the D3/D300/D700/D200. There is a rumor that the next D800 firmware update will address this.
