I've taken 645s on canoe trips (film) and somewhere have a moose image taken with a Mamiya 645, so it wasn't me that said that. What I will say is that, it's not a system optimized for that kind of shot. But, big camera, heavy lens, MF, maybe it will give some of the "I can't get the shots I want without great AF" types pause for thought. The need for fast AF is often way overstated, and the results of those who switch to get it are often less than impressive.

Exactly.
A good wildlife photographer who can use higher resolution but harder to use cameras has a leg up in terms of the final image, on those who need every mechanical advantage to get their images, which usually means 20-24 MP files.

If you're like me, you take the picture you see with the gear you have with you. No need for someone else to tell me what a camera can or can't do. Experience trumps the commentary of the nay sayers. The question should be not whether you can or can't but, how, if you have a particular set-up, you can use it in various circumstances.
