Hi, I also have just subscibed to this list and I am also building a Wide angle camera. I am considering a number of options that you might consider: 1. using a variety of "stacked" lensboards to achieve a variety of depths of field for a fixed lens camera. 2. Using an antique Goerz helicoid focusing unit adapted by taking out the original elements and f/stop diaphram and mounting a shnieder angulon lens and shutter into the helicoid somehow . These Helicoids can be found for pretty cheap on a number of old camera's. These are primarily low cost alternatives and I am sure there are better methods. However, I am on a budget. As always.lol Hope this might help.
