The original application for the S-Biogon 5,6/40 was the archiving of quality newspapers for institutions like the National Archives and the like. In the pre-computer era this was done with specialized copy-stands. They would capture a double spread, 2 pages side by side, in one shot on high resolution microfilm. The performance requirement in this application was, that the finest detail contained in a newspaper should be still detectable/legible in a large print from the microfilm negative. The S-Biogon served this purpose excellently. The correction and manufacture of this lens is so flawless that its perfomance is limited only by diffraction.
At Zeiss today, we have our lab use our last remaining S-Biogon 5,6/40 whenever we order performance demo prints from 35 mm negs or parts of medium format negs at magnifications in the range of 20x to 50x. The results we get are visibly superior to anything generated with even the best enlarging lenses.
