Kai from DigitalRev TV seems to agree with me.
He’s giving us his 5 reasons to use the 70-200mm lens. He’s using the Canon 70-200mm lens here but he is talking about the overall benefits of any 70-200mm lens. I love using mine when I shoot moving elements, such as sports and dogs. And for portrait work my 70-200mm f/2.8 is simply amazing.
