B W 40.5mm #803 MASTER Neutral Density 0.9 3-Stop MRC Nano Filter

The B W 40.5mm #803 MASTER Neutral Density 0.9 3-Stop MRC Nano Filterreduces the light by three f-stops and is particularly interesting for video when no suitable aperture can be selected in bright light or when a specific, small depth of field is required. With this filter, distinct flow of water effect becomes apparent. The B W 103 ND filter 0.9 is also ideal for shooting photos with a wipe effect.MRC Nano coated glass is used as the basis for the new Master filter line. This guarantees the necessary optical quality and also does not have any adverse effect on a correspondingly high-quality lens. The MRC Nano coating contains a multi-layer anti-reflective component with 7 layers per filter side to prevent annoying reflections. An outer layer with the usual dirt- and water-repellent properties is applied as the final layer. This not only provides all-around protection for the filter, but also makes it easy to clean and maintain the filter pane. The light attenuation itself is very uniform over the entire visible range and produces optimally color-neutral image results. Features: Reducing the amount of light entering the camera Suitable for both analog and digital cameras Selective sharpness by achieving larger apertures ideal for portraiture Long exposures producing a cotton candy effect on moving water and deserted streets void of people and cars Wipe effects, continuous light trails Made in Germany *Please Note:ND filters must not be used for direct visual solar observation (risk of blinding). They let through UV- and IR-rays which harm the eyes.Special sun filters for direct observation of the sun are availablefrom astronomy suppliers.
