Has anyone used rear gel filters with the Phamiya 28D?
I'm looking to use some significant ND filtering (10-15 stops) with this lens but the Phase One guide that came with my lens offers no instructions about how to best use gels. I know that it'll be a real pain to have to fit/remove the gels and lens between compositions.
I REALLY don't want to screw up mounting and have a mirror accident! Any advice on using it?
