What part of it was so amazing? Most of these innovations seem to apply to entry level consumers and those not knowledgable about cameras. He seemed to make a big deal about face tracking and a $7k camera not having that, but if you use a face tracking feature for your autofocus you probably are not skilled enough to be using a $7k camera in the first place.
Nonsense. That's a non sequitur. It's like saying that for people who use automatic transmissions are not skilled enough to drive stick, or saying that people who use automatic focus or any of the semi-automatic Av/Tv/* modes are incapable of using a manual iris or manual focus lens.
People use different tools under different circumstances and for different reasons. Face detection AF is great in live view modes, because manual focusing is harder on an LCD screen. It's also great for video, assuming you're using AF at all, because it makes AF a lot more usable.
For example, I have a 44M that I use for portraits on occasion, and I often end up in full manual mode when shooting anything on a black stage (concerts, plays, etc.) to avoid blown-out faces. But when I'm walking around with a tour group, dealing with wildly alternating amounts of light, I'd miss a lot of great shots if I were trying to manage all of those extra variables. In those situations, I'd estimate that 99% of my shots are done in P mode, with autofocus, and with automatic ISO. The nearly fully automatic setting does a good enough job in most typical circumstances (sometimes a little overexposed or underexposed, but not enough to ruin the shot), freeing me to focus on more important things, like choosing a good shot angle, nailing the timing of the shot to get good facial expressions, and all the other myriad things I'm thinking about in the background. And this is how I come home from a two-week trip with 6,000 photos, with only a single-digit number of shots that are bad enough to throw away.
Would I use face detection? Maybe sometimes, so long as it is a quick knob twist between that and traditional focusing modes, and so long as they also add an in-viewfinder indicator to tell me what shooting mode I'm in. Then again, I guess it would be obvious, because that mode would switch over to an EVF, and none of the other modes would, so....
A trained experienced cameraman will put an evf to his eye and his fingers will turns the lens the right way enough automatically.
Or, if he or she is used to that other camera system, an experienced cameraperson will automatically turn it the right amount in the wrong direction every time....
