Lumenier LayerLens for GoPro 3 & 4

This is the newest revision of LayerLens for the GoPro 3 & 4

LayerLens for the GoPro 3 & 4 camera series features a hard and anti-reflective ("AR") coated lens with an anti-smudge coating on the viewing side. AR coating is applied to both sides of the lens which ensures low external and internal lens reflections.

• This new design features an injection-molded uni-body lens holder that is light and tough.
• Ships with 1 high quality lens. The lens is a 2mm thick, photo grade, hardened, anti-reflective and smudge coated cast acrylic lens.
• None of the video or photo modes show the bezel.
• Fits all GoPro 3 & 4 models, but does not fit the GoPro 1 or 2 (see our LayerLens model for the GoPro 1 and 2).
• Upgrade the lens to a Circular Polarized Lens to cut down on glare and reflections.

Product Background

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.

For this reason, Lumenier developed LayerLens. LayerLens brings the most important part of the original GoPro case back: the protective lens; without adding much weight or size. Fully assembled, LayerLens for the GoPro 3 & 4 weighs only 7.5g — a small fraction the weight of the full GoPro case. LayerLens has become the standard lens protection product in the fields of RC and FPV where a GoPro is used outside of its standard housing.

Assembly and Care Instructions

The included lens is covered with 2 protective films. One film is green -- this is the inside surface of the lens that faces the GoPro lens. The other side has a clear film -- this is the 'viewing side' of the lens that faces outward. Both sides of the lens are hardened and AR coated. The viewing side of the lens has an additional 'anti smudge' film to minimise finger prints. Remove both films of the lens and remember which side is the viewing side. Mount the lens on the black base with the viewing side facing outward. Screw in the 4 screws with a small phillips screw-driver. Do not over-tighten the lens -- apply gentle turning motion when screwing on the lens and stop when you feel resistance.

Thread the velcro band through the two small holes in the base to attach the assembly onto your GoPro

The AR coating on the lens requires special care. Only clean the lens with a cleaning solution appropriate for cleaning lenses or eye glasses and with an appropriate microfiber cleaning cloth. Try to avoid touching the lens. Never use ammonia based cleaning solutions. For example, never use Windex to clean your lens as it will permanently damage the AR coating.
