I am currently using -Apo Rodagon 90mm f1:4mm for all medium - 50 mm -n f2.8 for 35mm - Apo Rodagon n 1:4 f 150mm for 4x5

I really like the coverage of the 90mm I have a bunch of 80mm Apo that I never use because of the two 90's.

for murals laser align the neg stage to wall or baseboard,,, as well glass carriers,, as well mask out the neg,, as well get rid of any flare light.
