Feature: 1. Durable and Antislip: Compatible for Insta360 GO 3. The diamond cut design on the edge of the frame provides a comfortable grip and prevents slipping when installing or removing the lens. The aluminum alloy frame is rugged and durable, with laser engraved text that is fade resistant. 2. ND Filter for Light Reduction and Long Exposure: The ND filter reduces the amount of light entering the lens, preventing overexposure and allowing for longer exposure times. It adds a sense of speed to action shots and creates silky smooth flowing water effects, as well as dynamic sky and cloud imagery. 3. CPL Filter for Reflection and Glare Elimination: The CPL filter eliminates reflections on object surfaces, restoring clarity, texture, and color saturation in bright environments. It is commonly used to reduce glare on glass objects, eliminate scattered light on water surfaces, and reduce oiliness on skin. 4. Optical Glass and Double Sided Multilayer Coating: The lens is made of optical glass, similar to those used in DSLR lenses, ensuring high definition image quality. It is scratch resistant, waterproof, and oil proof. The multilayer coating reduces light reflection between the lens surfaces, resulting in clearer and superior image quality. 5. Waterproof and Anti Fog: The built in gasket in the frame effectively seals out water droplets and moisture, allowing you to capture worry free shots underwater, in rain, and in damp or low temperature environments.
