    I have a Goerz 19 inch f 11 lens, which I never use, but have no idea of the coverage. It is not a red dot, meaning it is pre 1950's (red dots came out then, I think).

    It seems to cover 8x10 with no problems, but I don't know the max coverage.

    Any thoughts on that?

    I get more movements with my 12" Dagor than I can my 19" Artar on the 8x10, but the Dagor is a little mushy at the edges if I use movements. It was made in 1911. The Artar (which is a Red Dot) is more uniformly sharp from edge to edge. It's angle of coverage, BTW, is 46°, with an image circle of 16.1" at f/16. Since it's an early one, the Dagor's angle of coverage should be about 85°.
