Hello all, I've found this huge lens on e-bay, Gundlach-Manhattan Hyperion Diffu sion Lens, item # 1270036754 . I was wondering if anyone has seen the kind of ca mera which would take this kind of lens and what kind of film would you use? If it's 11x14, do you use reducers to make smaller prints or is it just to make 11x 14 and bigger? Also, why does it have different f-stop readings for different fo cal lenght? It has 12, 18 and 30mm setting, but how does it work if it's not a z oom lenz?
