Hi !
I would like to know what is the distance between the flange and the film for th e 121 / 8.0 Super Angulon when focused at 18 feet. Reason for this question ? I' m building Super wide 8x10 camera and I need to know the starting point for plac ement of my lens board. I will do fine tuning with shims. Thanks.

Sorry, I overlooked 18 feet. Focal length is 121.6 mm and flange focal distance is 132 mm @ infinity. If 18 feet is 5486 mm then the focal point is at 124.36 mm. So the flange focal distance @ 5486 mm is 124.36 * 132 / 121.6 = 134,99 mm.
Kind regards.
Thank you Ruud !
Internet is great especially when great and knowledgable people are at the other end.
