Thanks for the thoughtful reply... my 75 SA is the older f8 version which has a published 180mm IC at f22.... time to upgrade!
Did you modify your 5x7 holder to do 2 shots? I'd love to see your workflow.

I did not physically measure the IC.
as per specification: Schneider Super angulon 75mm F5.6 ( all 3 versions ) are having IC at 198mm ( not 180mm )
it should noted that IC is measured at F22 , and not wide open.
I have a center filter 3A infront of the lens, and I think, it will reduce the IC a little bit.
5 inches is 25.4 x 7 = 177.8mm
at half frame, the corner should be OK, but if you use full frame 5x7, then the corners will be dark.
I did a simple CAD file to see the coverage.
