Enhance Your Photography with Our ND2-400 Adjustable Camera Lens Filter Adjustable ND Filter: Transform your photography with our innovative adjustable ND filter, featuring a unique combination frame that allows for smooth transitions from light to dark. By rotating the frame, you can easily adjust ND values from ND2 to ND400, enabling precise control over exposure and light levels. CPL Stacking Technology: This filter utilizes advanced CPL stacking technology, combining two CPL filters to deliver a versatile ND range from ND2 to ND400. This makes it an excellent choice for long exposure photography, capturing stunning motion effects and dynamic landscapes. Please note that this filter does not support higher density levels such as ND1000 or ND2000. User Friendly Design: Designed with ease of use in mind, this filter includes a scale range to help you achieve consistent exposure across your images. Simply adjust the filter on your lens and monitor the brightness levels. For high-density situations, a long exposure of 4 seconds or more is recommended to ensure even exposure throughout the frame. Moire Pattern Elimination: Moire patterns can occur with adjustable ND filters, but they can be minimized with the right techniques. By using extended long exposure at the 'X' position, these patterns can be effectively eliminated. Keep in mind that there is a limitation at the ND1000 level, so the recommended usage range for optimal performance is ND2 to ND400.

These materials are not only lightweight but also highly resistant to breakage, ensuring that your filter remains intact and reliable through rigorous use.
