Rated 1 out of 5 by RickBennette Out of Focus
This case is designed to allow your Action Cam to shoot under water. There's one big problem. The underwater video is completely out of focus. And here's the reason. Water has a greater index of refraction than air, meaning that the water bends light rays more than air does. This does not happen if you use the case out of the water, because the air on both sides of the lens cover has the same index of refraction, allowing light rays to pass through straight in line. But once there is water on the outside, the higher index of refraction of the water against the curved surface creates a lens effect, which causes the light rays to bend and creatie an image that is out of focus. If the camera lens had an automatic focus mechanism, it could compensate somewhat for the bended light. This camera lens, however, has one fixed focus, and so it can not compensate. The only solution to this problem is for Sony to redesign the front lens cover with a flat surface on both sides so the light won't bend in air or in water.

Rated 2 out of 5 by FeAll Not as good as claimed
The SPK-AS1 box claimed to secure underwater shooting.
In fact it does keep water out OK, yet the image is severely out of focus.
In fact that gadget spoiled my short vacation.... Should have taken my old camera with me...
