I was up in the Sacramento National Wildlife Refuge last Sunday in the central valley of northern California, shooting birds. This was the first time I was using my D4 after the firmware upgrade. My un-scientific seat of the pants review is that I can't really tell much of a difference. Focus was already lightning fast and accurate, and it is at least as fast now--I don't even know if I could notice faster focusing than i was experiencing prior. However, when i look at these shots I am really happy with some of the focus detail, so maybe there is something to this firmware upgrade after all. I will probably post some bird closeups in the next day or so on the wildlife board. Anyway, for me at least I can say the firmware might have improved things a bit, but I had no issues before so it is really hard to tell. I wish Nikon would give some better metrics around what the expected benefits are to firmware upgrades.
