Today I wish to present three cameras fabricated by Chave Treze from Portugal. He has several handmade cameras to his credit and I'll present three of his cameras which are of panoramic format. You can visit his webpage at http://chavetreze.blogspot.pt/
The first one is a converted Nikon F3 panoramic , with a Holga Lens that yields 24 x72 mm exposures. The details can be found here.
There is a nice video on the last camera in action:
