I just picked up mine from The Camera Store in Calgary. Its very nicely built, and looks robust, and it holds a film holder tightly against the frame. I will be using it tomorrow.
I believe that there is a 10x8 version in the process of being made with the different cones (focal lengths as well) . Plus for those still trying to get hold of the 5x4 version if you go to
walkercameras.com/pinhole_cameras.html you can order direct. I think the price quoted is excluding VAT but not sure.
Last week we sold our 1,000th HARMAN TiTAN camera, amazing. Thanks to everyone who bought one, has one on order...Press release is on our ILFORDPhoto website.
