Cambo Wide Focus Adjustment Help Needed

[Richard Wasserman]

I have a Cambo Wide 750 that needs the hyperfocal focus scale adjusted. As it is now it is not getting infinity sharp. I assume this is something I can do myself, if I only knew how. So, how do I do it? Loosen some screws, big wrench....

Also,any idea what to set the focus distance at? I'm thinking about 25 feet That's according to Schneider, but I don't know what size circle of confusion they used—I want to print up to 20x24

Turned out to be pretty easy. It's a matter of loosening the 3 screws that hold the helical together and setting the focus ring where it should be. A few iterations of that, along with a good loupe and I think I'm in good shape. I'll run some film to make sure.
