Hmmm, tough choice. I would immediately jump on the 85 1.8, but the 100 will give you more of a distance to your subject and put them more at ease...Originally Posted by modafoto
MMmmmm....I say the 100 f2. Forget the 2.8 (I use one for portraits and would love the 2.0)
Actually, I use the 80-200 2.8 L for portraits....So the 100 would be great IMO.
