The NX-Series Discovery Filter Kit from Cokin features a soft-graduated ND filter, offering you precise control of exposure across your frame. The NX series holder allows you to use square filters on threaded lenses, helping to reduce the effect of vignetting some threaded filters create. Multiple adapter rings also make the NX filter holder compatible on 72, 77, and 82mm lens threads.
Graduated ND filters are denser in one area and lighten across the filter, allowing you to control highlights and shadows in separate parts of the frame, which can be especially helpful when shooting images with a clear horizon line. The inclusion of a 3-stop filter with the NX series holder allows you to swap or stack filters to suit your exact needs and conditions. A convenient carrying pouch also makes it easy to transport your filters while always having them within reach
