You are very right at that, no argument here.

You are right again.
It is just your reference to professional wildlife photographers I was refering to.
I guess they don't use an amature camera and a tripod for all those reasons. With birds, fast moving targets and the like you are more late than anything else.
I guess professional wildlife photographers (and I have only 1 reference), have other options available that may fit these circumstances better.
