The Khronos Magnetic Filters are specifically designed to be used with the iPhone 15 Pro and Pro Max. These filters easily drops into the Khronos Quick Release Filter Tray for iPhone when using the Khronos iPhone Case. These filters come in various levels of Neutral Density, providing users greater control over their exposure. This allows users to reduce light visible to the sensor, allowing you to keep your shutter speed consistent when shooting in brighter lighting environments like daylight. Full Spectrum ND Filters evenly reduce all wavelengths of light including visible light, ultra violet, and infra-red.
