I'm very interested in your 8 Door Shade conversion! Any chance of posting a few pics.. I made a magnet mounted Lee wide angle shade so that it would work with my 80mm SSXL but would like to have some more adaptable from my longer lenses..
Is each flap (of the four) able to be adjusted independently?
p.s. Here is my Lee filter adaption and a little talk on why it's needed with large image circle lenses..
