1. This waterproof case does not include a touch screen back cover. Without the touch screen back cover, adjusting camera settings requires removing the camera from the case. With the touch screen back cover installed, you can operate the camera directly without removal. 2. The optical design fully encloses the lens, enhancing protection for the waterproof lens and improving focus accuracy and image clarity compared to an exposed metal lens. 3. Heavy-duty sealing with factory pressure testing. 4. Why use an anti-fog insert? During water-based or cold-weather activities such as diving, swimming, skiing, surfing, and mountaineering, temperature differences between the inside and outside of the waterproof case can cause condensation. The anti-fog insert absorbs moisture vapor to prevent lens fogging. It is reusable after drying. 5. Without the touch screen back cover, adjusting camera settings requires opening the waterproof case. When diving or swimming, this process is inconvenient and repeated opening may increase the risk of internal fogging or water ingress, affecting image quality.
