WOW, "Holly speed demon Batman". I have been using a D3 for a few years and thought it was fast, WOW. Used the D4 for the first time last evening to shoot some Bball. You can just put the focus point on a player running toward you and it will just keep firing, I mean as long as I would hold the release down, no stopping. An all in focus to boot. Did I say WOW? I think the new thing that is the handiest is the locked focus point between landscape and portrait. Still learning all the new stuff. Did I say "WOW".
