Breakthrough Photography X4 3-stop ND (77mm) brand_Blazes Photographic 4X N-AF MC4 for NikonBreakthough Photography calls this an "X4" filter, but it's a 3 stop ND, which actually makes it an 8X. The branding is confusing, but the filter is good, with neutral colours and an easy grip frame. In excellent condition. For 77mm thread size.
