The 70-200mm f/2.8 is the perfect companion to Canon's 28-70mm f/2.8. Its zoom is flexible enough for a wide variety of applications including sports and portraiture and it's bright enough to use under the lights of stage or stadium.
It's also especially useful for extending the range of your flash (extra important with a lens that can get you closer to far away subjects). Like the 28-70mm, this is part of Canon's series of lenses and, if you haven't shot with it, you'll be amazed at just how sharp Canon's Fluorite glass can be.
Coupled with the 28-70mm, you'll command a range from 28 to 200mm at a bright and useful f/2.8 throughout the entire range!
