Replacement Lens Cap
This replacement lens cap snaps onto your Apro case to protect your Gopro camera lens when you aren't shooting. Alternatively, you may use the optional UV protective filter to protect your Gopro lens.
While some photographers insist on a filter to protect their camera lens, others prefer to have nothing at all in front of their lenses, which might, even slightly degrade the performance of their lens. Either option is yours. Use the lens cap which comes with your Apro camera housing or add the optional filter for protection.
