Thom Hogan dives straight into features about which many of us await enlightenment
"......Nikon had told me earlier that you couldn't turn subjection recognition on or off via a button. They're wrong. As Brad Hill has also noted, there's a way to do that, though it involves dedicating Recall Shooting Functions to this. I'll give you an example of where that might be something you want to do: a team wins the championship trophy and a player suddenly thrusts this forward towards your camera. You probably want the trophy in focus, but if the player is in the frame and human subject detection is on, the trophy will likely be right up front and out of focus. Press the button you assigned Recall Shooting Functions to (with Subject Recognition Off) and if you're in one of the two Wide-area AF modes focus should move to the closest thing (the trophy).
Which brings me to a "kudos". Kudos to Nikon for finally realizing they shouldn't be so paternalistic on button assignments. On at least one recent Nikon camera, Fn3 could only be assigned to something like six things. Why, I have no idea. Three of those were things I'd never use, so basically this meant that one function button really had to be relegated to a couple of things I "might" use (as opposed to "do" use)....."
