#D1D3D4 ND030 Neutral Density Filter - Absorptive 50% Transmission

ND030 absorptive neutral density filters have an optical density of 0.3, or average 50% transmission across the visible spectrum. These filters include identical male and female threads on either end so that they can be stacked with other ND filters to achieve various optical densities. For example, two ND030 filters stacked together would perform approximately the same as one ND060 filter.
