From post #1,

I am looking at Rodenstock Sinonar-S 210mm or the Nikkor W-210mm.
These are 5” x 7” format lenses. They can’t fully cover the diagonal of an 8” x 10” film. You need to check the diameter of the infinity-focus image circle of any lens you might choose and verify that it is large enough to properly cover the diagonal of your film size.
