I've used my 85mm f/1.8 AF on my FE2 in auto photographing the family kids. I found the "plasticky" feel of the manual focus to be an advantage as there was almost no drag while focusing. I could use just one finger to quickly fine focus, we are talking 1-2 inches of FF. This lens has extremely shallow DF at close range when used wide open so fine focus is critical. Using an AF body is easier but to me it doesn't always pick the exact spot I want to focus on even with multiple focus spots in the viewfinder.
