Ian,

I was not presise. I mean how can I know before purchasing the lens, how wide focal lenght my Bergheil 6x9 or 9x12 or any plate camera can accept giving me possibiltity of making pictures without any limitations ?
I want to buy and adopt Angulon 65mm f/6.8 but I am not sure if I can use this focal lenght with my Bergheil 6x9...
excuse me for that maybe simple question.
