I've got a similar device that's been sitting here in my bookshelf for a few years, waiting to be constructed. Its a "Sharan Wide 35 Panoramic Pinhole Camera". Now I just need someone to make a CMOS sensor to put in the back. :-)
Talk to a stranger today!
Some Fuji gear; Speed Graphic (gathering dust); Polaroid 250 (waiting for an 'art' project)
