This weekend I made my broken Lubitel 2 into a really crude pinhole camera. I took the whole front bit off but couldn't do anything for the broken shutter. My pinhole was made with a pie tin and my shutter is a bunch of tape. Quality craftspersonship!
I also began work converting one of the Spartus Full-Vues into a pinhole. It doesn't have a tripod mount so I'll have to make a contraption for it. I'm waiting to see what I get with the Lubitel before making a decision on whether to buy a precision-drilled pinhole or go the pie tin/pop can route. I find it difficult to wrap my head around the idea of spending 40 or so bucks U.S on a teeny hole when the camera itself wasn't more than a few dollars total.
