(I leave aside the issue of enlarging and circle of confusion.)


Furthermore Kubrick used the lens on a viewfinder camera. Focussing was most probably done done by means of tape.
Oh! So not movie size....

Also when I mentioned the size format, I was thinking of the comment someone made about the physical size of the glass, and I was saying of it were closer to an APS size area, the glass wouldn't have to be as big to pull off f/0.70 that's all.
