I've got a lens that was designed to be used in military aircraft to photograph the wake of torpedos as they were launched from the airplane. The cameras produced 7" wide photos. So I'm thinking to myself that that's a pretty big image circle and it might make a nice tilt lens for my 35mm camera. Has anyone made, or does anyone have plans, for building the tilt mechanism? I know lensbabies makes them but buying one is nowhere near as fun as building one. No particular lens mount or anything just the swing part. Greg
