My camera of choice is a Nikon D500 and my go to lens is the Nikon 200-500 f/5.6, this is not a professional lens but it is my go to lens for wiidlife photography at the moment, its lightweight, portable & yields excellent images as can be seen here.
When used on a crop snsor D500 it also give me extra reach as I at 500mm now shooting at 750mm which is a huge plus. The vibration reduction also works well with static subjects as I can hand hold mdown to 1/15th second at times.
