This is probably going to work best! A method already employed by most all cameras with lengthy bellows, I don’t know why I didn’t try this first. Of course, I can’t say yet that the issue is solved outside of my living room with a wide angle, but the next shoot should provide those answers. This is a 1/8″ sheet of pvc which has been cut with a knife and placed in the center of the bellows without glue. I had initially thought to contact cement the frame, but maybe it’s no necessary?
