Hi All
I am building a large "mammoth" Camera, 12x18, And I have A lens for a argus c3 that I was going to use as my lens. but I know that the f-stop relates as the distance from the hole to the film Plate. So if the lens says F5.6 for 35 mm that would but much smaller for my
12x18 format and I need this equation so I can use the C3 lens and write the new F-stops on it. IF anyone has any help please let me know.
John
