1. Made of whole beef tendon, the friction and wear resistance are very good.
2. From 86mm to 37mm in diameter, a stepped design is adopted, and 16 different sizes are realized by 7 double-sided cylinders.
3. Each surface adopts a concave design to avoid contact with the lens when opening the lens, thereby avoiding accidental damage to the lens.
4. The height of each cylinder is 50mm, even the double mirror ring can handle it.
5. Size: 37-40mm, 43-46mm, 49-52mm, 55-58mm, 62-67mm, 72-77mm, 82-86mm.
