Compatible film cassette solution for handroll and bulk 35mm film Key benefits Enables automatic ISO recognition: equips a film container with a filmrecognition/DX system so your camera can read film sensitivity (ASA/ISO) and latitude automatically and use that information for exposure. Keeps handroll and bulk film usable with automatic cameras: solves the problem of cameras rejecting or misexposing film that comes in nonDX or neutral reloadable cassettes. Broad compatibility: fits handroll pan film and bulk film loaded into reloadable cassettes, and also fits other 135 (35mm) 36EXP film cassettes that do not have DX coding. How it solves common problems Automatic exposure accuracy: when a cassette/container lacks DX coding or when handrolled film data differs from the cassette, your camera may not receive correct sensitivity data. This product provides the missing recognition so the camera's automatic exposure system can set the correct exposure. Reduces manual settings and guesswork: no need to remember or manually set ISO on every frame when using bulk or handrolled film in nonDX cassettes. Compatible with a variety of reloadable cassettes: works with neutral/noDX containers and standard 135 36EXP cassettes without DX coding. Important attributes Function: provides filmrecognition data (sensitivity/latitude) to the camera's automatic exposure system. Compatibility: hand roll pan film, bulk film, reloadable/neutral containers, and 135 (35mm) 36EXP cassettes without DX coding. Performance: restores automatic ISO detection and improves exposure reliability when using nonDX film containers. Use scenarios Street or travel photography: convert bulkloaded 35mm film into cassettes that your automatic camera can read, so you can focus on shooting without constantly changing ISO settings. Darkroom or handrolled projects: handroll specialized films and still let modern automatic cameras detect sensitivity for consistent exposure. Film lab or hobbyist reloading: when reusing neutral reloadable cassettes or fitting bulk film into 135 cassettes without DX, ensure the camera receives correct exposure data. Note Some reloadable film cassettes/containers are neutral (no DX information), and the film data in a handrolled setup can differ from the cassette. This product addresses that mismatch by supplying film sensitivity and latitude data to compatible cameras.
