I have not - I wonder how much IR there is in a studio flash. I also wonder how much af a filter you would use. none? then the difference would be small, R25? more pronounced but then how much IR is there to see? 89b? There may be no light at all in the studio for this one. It would be an interesting experiment though - i have some Konica loaded up right now, maybe I'll give it a try this week.
