The [terraPin 6X6](http://www.thingiverse.com/thing:495230) is a pinhole camera for 120 film with a 6X6 frame, in a square format. This design consists of a slide-in replacement extension that changes the focal length of the pinhole camera. This affects "shutter speed", angle of view, and, possibly, depth of field.
Designed for 0.22mm diameter pinhole
f/115 center, f/132 nominal
Horizontal and vertical angle of view: 95.6°
This is a "fast", wide-angle extension for the [terraP
