Eumig Nautica questions in Super-8 Posted February 23 · Edited February 23 by Andrew Law I recently bought an Eumig Nautica to use on a project. The manual says the only film to be used in this camera are of ASA: 25D, 100D, 40T, or 160T. The camera is fully automatic and there is no way to set the film speed. How does the camera tell what speed film I am shooting on? I would like to shoot on Vision 3 film. Either 50D, 200T, or 250D. What would the camera read these films as? For example, would 50D be read at 25D or 100D? And so on. I am going to have the film scanned in raw and a flat profile to get the most latitude, but am curious what my best bet would be.
