Jim, I have a question for you...

How the Hell* do you mount these lenses to a camera????

I have three Great Big Plate Cameras with Universal Iris Mount, but even the biggest one has no chance with these mosters! Even the rigid front of the 24x30cm camera looks like it's sagging!

Or do you mount a camera to the lens???

*"Hell" is not an epiteth, but a station on the railway Northwards from Trondheim, quite close to Værnes Airport. One particular sign at that station is very popular with tourists - it says "Hell Station - Gods Expedition".
