Description
The Leitz BEOOY (Hilfsgerät für Nahaufnahmen / Auxiliary Device for Close-ups) is part of a modular Leica system for close-up photography and slide copying, designed primarily for use with Leica screw mount cameras and lenses (typically a 50mm Elmar). The BEOOY itself is often the intermediate tube or extension ring component. When combined with other parts like focusing stages (e.g., BOOWU), bellows units (e.g., BALDAF), or slide copying stages (like the BEHOO), it allows precise reproduction of documents or duplication of slides. BEOOY is just one piece, often needing other components for full functionality.
