- Waterproof Depth Rating: Specifies the maximum depth the case can withstand. Look for a rating that exceeds your intended use (e.g., 10m, 30m, 60m).
- Camera Compatibility: Crucially, ensure the case is explicitly designed for your Osmo Action model (Action 4 or Action 3). Cases aren’t universally compatible.
- Material: Durable materials like polycarbonate plastic or high-strength tempered glass are preferred for impact and pressure resistance.
- Lens Window Clarity: The lens window should be made of a clear material that doesn’t distort or reduce the quality of your underwater footage.
- Button and Control Access: The case should allow easy access to all essential camera buttons and controls, even underwater.
- Ease of Use: Look for a case that’s easy to install and remove, with secure latches or seals.
- Mounting Options: Check if the case includes mounts or threads for attaching accessories like lights, handles, or tripods.
- Included Accessories: Some cases may come with extras like anti-fog inserts, lanyards, or cleaning cloths.
- Build Quality and Durability: A well-constructed case will offer better protection and last longer. Read reviews to gauge durability.
- Price: Waterproof cases range in price. Balance your budget with the features and level of protection you need.
