Material durability: Priority is given to anti-aging and pull-resistant rubber materials to avoid cracking after frequent opening and closing. Sealing: Ensure that the lid fits snugly with the body interface, and has the function of dustproof and waterproof splash to protect the internal circuit. Ease of opening and closing: The design needs to be both compact and easy to open, so as to avoid falling off or damaging the interface if it is too tight. Fixed structure: Check whether there are anti-loss designs such as buckles and hooks to prevent the lid from being lost. Compatibility: Adapt to the camera model to avoid poor closure or inability to install due to mismatched dimensions.
