Grouping the 70/80-200/210 zooms together is a mistake, those Vivitar Series 1 zooms are well regarded as top notch for the day, but they pale in comparison to the truly modern 70-200s by the camera manufacturers. Nearly every facet of image quality has truly been advanced by better coatings and computer optimization for this design segment. I cannot say the same for most primes, apart for ultra-wide-angles.

That being said, unless tasked with event coverage where I simply must get the shot (and am being paid to do so), the 70-200 range solves a lot of problems that would take a lot of other glass to solve similarly well. The most recent Canon 70-200 2.8L IS II is astoundingly good, but yes, it is a brick in your bag.
