Freewell ND Filter 4Pack only compatible with Galaxy Series Cases

The Freewell ND Filter Kit for Galaxy S23 Ultra is a 4-piece set of precision optical filters specifically designed to enhance smartphone photography. These neutral density filters effectively reduce the amount of light entering the camera lens, allowing for controlled exposure time adjustments to achieve professional motion blur effects in photos and videos. Made from high-quality optical glass with advanced multi-layer coating, the filters maintain excellent image sharpness and accurate color reproduction while providing protection against water, dust, scratches, and oil. The innovative magnetic mounting system enables filter changes in just one second when used with compatible Freewell Galaxy Series Cases, without the need for precise alignment. This kit offers versatile creative control for capturing cinematic shots of moving subjects such as flowing water, cloud movements, or urban scenes. The filters have a diameter of approximately 45 mm with a slim profile that seamlessly integrates into the Galaxy S23 Ultra camera system. Each filter features a robust aluminum frame construction weighing about 15 grams per filter for reliable performance under various shooting conditions. The complete set includes four different density levels for varying lighting conditions and creative needs. Proper installation requires the use of Freewell Galaxy Series Cases for secure magnetic hold and optimal optical alignment with the smartphone camera lenses.
