Some time ago i posted progress report -making of 6x12 anamorphic camera: http://www.f295.org/main/showthread....in-progress%29
first tests i made with zone plate. I left that camera on the shelf for many weeks, but finally i found some time to finish it. Camera work well, however i noticed two small issues.
1. Winding of film from start to first frame must be made very gently and carefuly- some films has very thin backing paper and it collapsed down several times
2. Adhesive foam added by me as a gasket wasn't 100% light tight and it caused small light leak at the edge. I replaced it for microgum foam.
A very nice looking camera. In the meantime you built an impressive variety of different pinhole camera models. Vermeer would be certainly proud that you used his name for your brand.
