    AI Overview
    M8P0.5 and M12P0.5 are distinct, commonly used metric thread standards for compact imaging lenses (board lenses/S-mount) used in security cameras, machine vision, and robotics. The M12 mount is the industry standard (often 12mm x 0.5mm), while M8 (8mm diameter) is used for more compact, space-constrained applications. 
    Key Differences and Technical Details: 
    • M12 Lens (S-Mount): Features a 12mm nominal diameter thread with a 0.5mm pitch. These are widely compatible with board cameras and are often used in 4K or machine vision applications.
    • M8 Lens: Features an 8mm diameter, commonly with a 0.35mm pitch (M8x0.35), though M8x0.5 exists. These are utilized when camera space is heavily restricted, such as in tiny robots or miniature surveillance units.
    • Interchangeability: M8 lenses cannot be directly screwed into an M12 mount. However, adapters exist, such as the CLA812, which allows M8x0.35 lenses to fit into standard M12x0.5 holders.
    • Applications:
      • M12: CCTV, robotics, drones, high-res AI cameras.
      • M8: Ultra-compact cameras, pinhole cameras, miniature drones.
    • Thread Pitch: Both rely on fine thread pitches (0.5mm or 0.35mm) to allow for precise manual focus adjustment by screwing the lens in and out, usually secured with a locking ring. 
    Common Configurations: 
    • M12 x 0.5: Used for 5MP, 8MP, and 4K lenses, supporting 1/2.5" to 1/1.8" sensors.
    • M8 x 0.35: Common in 3MP-5MP miniature lenses with 190-degree field of view options.
