Why don't you consider using Bolex 16mm cameras. If you contact Chambliss Cameras/Film Equipment in Atlanta, Georgia, they seem to be quite helpful in finding and maintaining this equipment, and the owner of Chambliss is in love with Bolexes. You can obtain quite inexpensive, but good 16mm film processing and work printing from Commonwealth Film, Inc. in Richmond, Virginia. I have been quite happy with their color negative processing and workprinting in 16mm. Does anyone have a 35mm slide to 16mm duplicator?
