Random thought of the day. Does any current interchangeable lens system have face detect AF that works on various animals? Maybe more correctly, it should be eye-detect. I think I've seen it in a compact, or was it a phone? But just curious if it has made its way into higher end models, and if so, how well does it work?
The application I'm thinking of is when you can get relatively tight shots of the head, and depth of field starts to drop where you don't necessarily want to stop down for more. Regardless of phase or contrast system, unless the AF point is exactly on the eyes, they can be off. Detecting the eyes would help in this context, for a moving subject you don't necessarily want to be manually shifting a point around nor be limited in the framing by fixing the point.
