I picked this lens up at an estate sale for 3 dollars, the previous owner was really into optics, but they were all taken apart this was the only complete lens at the sale.
Anyway getting to my question. It takes 13 inches to bring him into focus on my 8 x 10, I then put it on my argyle 20 x 24 process camera still 13 inches to bring it in focus but it covers the ground glass???
It's a coated lens and I see 7 reflections, has no writing anywhere, no f stop scale, but it does have an iris. I'm thinking maybe this was some sort of copy machine lens??
So how do you determine the image circle on something like this, and does anyone know what type of lens this is.
