The DOF changes in 7.1 are awesome, but that one little change would save a lot of time setting up an anamorphic shot. I wasn't too surprised it wasn't a choice to begin with, I don't see animators beating down the door to make those kind of lens effects happen, but, still, for those of us that want to recreate that, it'd be nice...
You beat me to it. Surprised they didn't have an oval shape.
