By single shot camera do you mean a "one shot" camera?
I gather Robland was meaning a one shot configuration. In my version, I will most likely approach it as a one shot at first. Building 20x24 holders might be fun, though. And costly. I picked up today what will be the rear standard, and another item that will be a contact printing frame.
Oh Robland, where art thou?
