I've built another panoramic pinhole camera for 120 film from ABS. It's similar to my last camera (see the posts below) but with a few improvements. This camera is also up for sale on ebay right now. The camera takes four 6x17 images on 120 roll film. I'll post some pictures taken with it soon (once I contact print some - I don't have a scanner that will do 6x17). The pictures are great, though! I've now had 4 rolls of film through the camera, and everything is working great.
The camera is welded together using ABS cement this time - the result was a very rigid and strong camera! The cloth tape is just for insurance against light leaks - it has no structural role.
The tripod mount is more professionally done this time.
The main difference is that this camera has spring-loaded film winders - so there is no need for a swing-out base. The camera is more solidly constructed as a result. The winders just pop up and the film drops in.
