Those guys drive me crazy running around on my roof; but then I have to forgive them, they have somewhat of a "YouTube cat" kind of attraction for me. Wanted to see if I can handhold the 200-500 with the extender, making it a 280-700 f8. Well, think it did not turn out too bad.

So this is at 700mm, f8 (as wide open as she can suffer), ISO 400, @ 1/125 and 1/250
