Mike, I suspect it was intended for a 5x7 camera, which is about 96 times the

The basics of making a very slow, moderately long lens aren't particularly difficult. Also, your use is only of the
center portion of the image circle. It could be pure crap in the corners, on the size film it was designed for, and you
would have no idea.
96 times is also misleading. It linear resolution that matters, not area. Yup,
ten times smaller is a lot, but not 100.
The things that make design with good results tough are speed and size/weight. Speed is obvious, I think. But the
pressures of the marketplace figure in, too. Example: I have the first version of the Nikkor-Q 200/4 lens, designed in
It is markedly superior in resolution to the later Oly 200/4 and 200/5. It is also a great deal larger
