I love this lens, but generally reserve it only for portraits. I was looking at the lastest issue of Photovision and in a segment on lighting at the reception, I was surprised to find how much these photographers used this lens (on 5D2 cameras).
It focuses so horribly slow I can't imagine it being very useful so I go with my 24-70, sometimes FF and sometimes crop. But I'd like to use it more. Anyone else do it much? Challenges with focusing?
I found the 24-105 pretty slow to focus in low light.
