Neutral density filter with a reduction of light from 16 3/5 stops, equivalent to a density of 5.0. Specially designed for solar eclipses, as completely coloured. The image with a 1,001 transmission of light under normal conditions can also be used to take photos with a larger aperture or with a shutter speed than usual. The colour is completely neutral, without changes in the final image. The aluminium frame guarantees the longevity of the filter when extra weight. This filter is not suitable for direct sun looking. Is for photographic purposes only.
