: Field Ektar when stopped down to say, f/32? Material
: available on this site seems to omit the 80mm version.
My copy of Kodak's "Camera Technique for professional Photographers (1952) gives a figure of 5 and 5/16th's inches at infinity @ f16. That works out to a 135mm image circle. I would think that stopping down to f 32 would add maybe 5-6 more mm to the coverage.
