I like my EF 200/2.8 a lot. Lately I've been tempted to sell it in exchange for a 70-200/2.8 IS as I might shoot some weddings though. My favourite 200/2.8 prime features are (1) black colour, (2) light weight, (3) 72mm filter size for sharing with my EF 135/2.0. Example shots from my EF 200/2.8:
Awesome color contrast in both photos!
