Post some shots with specular highlights when you get the lens. I'd really be interested in seeing that. I have a 50mm 1.8 and I really struggle with using a prime instead of a zoom. I'm going to try some studio shots today with the 50mm and some new light modifiers that I got. I just got a Lumiquest Promax system and an Alzo hotshoe softbox.

I usually shot ring candids with my 70-200mm 2.8 IS. Do you think you get enough reach with the 85 for ring candids. I usually shoot head shot candids and not a lot of full body shots, but do shoot a lot of dogs in the group, too.
