I am interested in the different mechanisms that cameras use to achieve movements... I've kinda been collecting images of different cameras for ideas when it comes to building. I picked up a rollfilm camera today at the swap meet for $5, that has one of the most interesting rise mechanisms i've seen. It uses a horizontal screw, and a lever that moves along the screw. The lever is connected to the lens, and pushes the lens up as the screw is turned.
Here is a picture of the camera, with various ammounts of rise: http://www.enteric.org/images/movements.jpg The camera is a Krugener Delta, and is equipped with a pneumatic shutter, and a lens around 135mm. I've never seen a pneumatic shutter, and it is most intreguing to play with. When you change the shutter speed when the shutter is cocked, the piston moves in and out of the cylinder; out for slower speeds, and in for faster. For some reason, I had always assumed that the orfice that the air was released from changed with different shutter speeds. It takes some sort of large roll film. It's bigger than 116... On the back of the camera, there is a door that is removable, revealing an opening that is 82mm x 115mm. I assume this is for a ground glass and sheet film back. This is definitely not the run of the mill folder.
