I am toying with an idea of making my own panoramic camera. If you have a LF lens/shutter in "I'm probably not going to use this" stage, I am interested in buying it from you. I am looking for focal length considered normal to wide in either 4x5 or 5x7 format. It has to work - meaning shutter must fire and reasonably accurate and lens can have some marks but shouldn't be that bad that it'll show in the final result. As this is my experiment, I would rather not spend all that much. Please let me know what you have and how much you'd want for it. I'm in Central Florida, US.
