The Thypoch M Mount Positive Lock Adapter M-Z has been designed for professional film and video workflows and features a positive locking mechanism similar to PL connections to prevent micro-movements caused by external forces such as follow-focus systems, ensuring image stability and recording safety. The model integrates a dual-locking system with a primary lock for a secure lens-adapter connection and a secondary safety lock to prevent accidental lens removal, enhancing reliability. The adapter includes a removable grip module that can be repositioned or replaced with a flat, non-slip module to avoid interference with camera button layouts or operating habits. Made from aerospace-grade aluminum alloys with CNC machining, it ensures precise flange distance and maintains the optical performance of the lenses. Durability has been confirmed through testing with over 50,000 mounting and dismounting cycles, supporting long-term intensive use in demanding environments. This adapter is compatible with M-mount lenses and mirrorless camera systems, focusing on practical benefits for stable and secure cinematography.
