The case that comes with the GoPro camera is beautiful, sturdy, and water tight, but it weighs about 100g and the included mounts make the camera stick up over 1″ with the overall surface area growing by a good amount. As a result, many FPV and aerial videographer pilots mount their GoPro without the protective case to save weight and provide a smaller overall footprint. The most significant issue with this “naked” mounting method is that the camera’s lens is directly in harm’s way. Any crash has a high likelihood of damaging the camera’s lens. Once the original lens is damaged, the replacement of the lens is an expensive option costing close to $100 USD — 1/3 of the price of a new GoPro2 camera and almost half of a GoPro Hero HD.
For this reason, FPV Manuals has developed a new, patent pending product we call LayerLens. LayerLens brings the most important part of the original GoPro case back: the protective lens; without adding much weight or size. LayerLens weighs only 11g — about 10% of the weight of the GoPro case. LayerLens is a precision laser cut frame that holds the protective glass lens and is pushed onto the GoPro’s built in lens. It sits tightly in place and is further secured with a small velcro band. In case of a crash that scratches LayerLens’ glass lens, you can easily swap out the scratched protective lens and replace it with one of the lenses that are readily available by GoPro as part of their “Lens Replacement Kit” (which includes 2 lenses for $14 to $20 USD).
The pictures below show LayerLens mounted onto an original GoPro camera, but it fits on the new Hero2 as well. LayerLens currently does not come with a glass lens, so you have to take a lens out of your GoPro case or buy a GoPro Lens Replacement Kit separately.
