OK thank you pannumon for your comments. I appreciate it.

Would the continuous AF be reliable for a bear in a pine tree ? Or a grazing elk or moose ? But not an animal that was walking away from or towards you ?

If you know how the camera operates and you know how to operate it, stationary animals should not be any kind of a problem. In fact I would just make initial focus and lock it there. Animal walking away/towards may or may not be a problem. It depends if you want the animal to be in focus 90% or 99% of the time. I would perhaps use manual focus, because even if the animal would be slightly out of focus for a moment, it would not be so distracting to the spectator.

Would their single-point AF be reliable under these same circumstances ?

I would say that the AF would be usable, but not foolproof. Most of the potential problems can be avoided by extensive testing of the camera, reading the manual and going through every related camera setting. As with stills photography, camera can always be blamed, but at the same time someone more skilled/experienced would probably have been able to eliminate the issue.

P.S. I see I am repeating myself, as I replied to you already in another thread.
