Designed to be used with the Khronos iPhone Case and Quick Release Filter Tray, the Khronos Magnetic FSND 0.6 Filter from Tilta reduces the amount of visible light hitting your phone's sensor by 2 stops, which allows users to have greater control over their exposure. With less light hitting the sensor, users are able to lower shutter speeds to more cinematic levels or create a shallower depth of field. ND filters help reduce reflections, glares, and flares, while providing clean and accurate color, thanks to a wavelength reduction for visible, UV, and infrared light. In addition, the filter offers protection against scratches, smudges, and debris.
