A friend has made some adapters for extending the lens on the waterproof cases. This allows you to use the original GoPro cases with a camera that has been modified with the Sunex lens. I personally like to use the cases even if not going near water as it protects the real lens on the camera and offers lots of mounting options.
One problem with GoPro waterproof cases is that the round lens on the case causes underwater pictures to be blurry. As a fix for those with the case extender, a flat lens has been created from high quality plastic. This allows for crystal clear pictures/video in the air as well as under water. It is also scratch resistent!
If you want to make camera fully waterproof, you have two choices:
1. purchase a 2nd O-ring. The official lens kit from GoPro includes 2 lenses & 2 O-rings for $20
2. But better solution is to purchase flat lens with o-ring for $15
The following options for purchase:
