Do any of y'all shoot the 85 L in a studio setting with a solid color background. Other than the blurring of the nose and face, it seems like it would be a waste.
I can't think of any significant advantage other than that. I almost always use my 70-200 or 100 for studio portraits since the tripod collar makes for quick vertical/horizontal orientation changes. Using a tripod allows me to pull my face away from the viewfinder to connect with my subject as I shoot, and closely monitor expressions at moment of capture.
The 85 is just too amazing on backgrounds and dof to shoot past f/2
