Wow, I just found this thread and that is a large lens. I just recently acquired an 11x14 Studio Deardorff which uses 8x8 lens boards. It would fit, but I may need to acquire a third bellows extension to fully realize its potential. But before that can happen, first I need to see what my newly acquired 11x14 Wollensak Varium f4 will do. I just cut a hole in an 8x8 board large enough to handle the flange which is 6 1/2"+ across.
