I was putting emphasis on friendliness! It seems you were written in this forum mainly to argue with people (judging by the other thread you yourself mentioned). Every person has different criteria for their needs in wildlife and birding photography just like any other kind of photography. With this in mind I do not need to have your permission to comment on this thread. And don't put words in my mouth. Once more - since you do not seem to have read that - I myself mentioned the 100-499 range advantage of Canon's RF lens).
EDIT: And another member in this forum mentioned D5 and yet another SONY 200-600. Should they get your permission too?
It's amazing you looked through my post history and concluded I mainly argue with people. You should probably look again and not cherry pick the one or two times I've DISAGREED with someone who was making an illogical statement.
AGAIN, thanks for painting me as "forum police" when that's just because you totally misinterpreted (and continue to misinterpret) what I said. I'm done talking to you.
