Canon EF 200mm f/2.8 L II USM
Facts
excellent telephoto lens
estimated retail price 840 EUR
in my use from 2/2010 to current date
comes handy when I feel like a paparazzi: takes close-ups from a distance
Pros
Cons
with 200 mm and with the maximum aperture f/2.8 some serious light and high ISOs are required indoors
at the limit of being too heavy for my shooting style so could be an overkill for a small DSLR body
IS could be helpful (but isn't IS only for wimps)
