Put a roll of Fujifilm NPS 160 in my Pentacon Six TL to photograph random things. I took most photos a month later though.
It looks like the focusing is more accurate after I adjusted the focusing screen. The flocking also appears to have heavily cut down on internal reflections. On the downside that means a lot of the character of my Pentacon Six is gone. But now I feel more confident in using it and not having to worry about bright lights from just out of shot.
