The way I understand it, this lens might just squeek by on 11x14 contact prints. I built a temporary box (cardboard and lots of black tape!) to try and get an idea of the image circle when using the front cell only. This "camera" was a little too primitave to tell me very much, other than the focal length becomes about 370mm and the image circle is enormous. I`d like to build a 8x20 point and shoot camera for paper negs., to be contact printed, if this lens will cover, and be reasonably sharp. As I`ve no way to test this without turning it into a project, I`m hoping someone has some experience with this lens.
