I just wonder if I could ever master the DOF with a lens wide open at f/1.4. I tend to find that even f/2.8 is challenging sometimes to properly tame for the right creative effect. I like fast lenses though, if for no other reason than I appreciate a nice bright viewfinder and easier focus.
I do think the 85mm makes more sense indoors though. A 105mm or longer is fine outdoors, but indoors I always feel like I just dont have the right focal length. I hate using the 70-200 for this type of thing because it is so heavy to handhold for a long portrait session.
I just found out about borrowlenses.com and it looks like they have a pick-up location here in Sacramento. I think I'm going to rent it for a weekend shoot and see how I do with it (and if I can get some keepers at f/1.4).
