Several posts also indicate using the 70-200 is a great portrait lens. Great compression and it's an "L" lens. Almost twice the money as the 85, but in my opinion much more versatile.
I like my 50 for head shots, my 85 for head and shoulders or on occasion 3/4 shots. The 70-200 can do it all, but you need a little more room indoors, which I use with artificial light sometimes. Outdoors always the 70-200. I have the f/4 non-IS which works well for me.
Actually, the 50 is best for full body shots, and longer lenses best for head shots.
