The Marumi Magnetic Grey Filter ND4000 (100x100mm) is a rectangular filter which allows you to capture a continuously changing landscape beautifully and easily. The Marumi ND4000 (Neutral Density) is specially designed for use with the Marumi Magnetic Filter Holder M100, which is available separately (see optional accessories). Due to the magnetic frame you attach the filter safely and quickly to the filter holder. The Marumi ND4000 then ensures that the bright light is controlled, resulting in a neutral photo color. In addition, you can slow down a certain aperture value by 12 stops. This filter gives you a slower shutter speed, while the aperture remains the same. This allows you to capture a movement without duplicating the moving image.
Furthermore, the filter glass contains a multicoating (Schott B270 glass), making it anti-scratch and water-repellent on both sides. This prevents for example fingerprints on the glass. The anti-static property of the filter glass also prevents sticking of dust particles and dirt.
Usage Marumi Magnetic Grey Filter ND4000
The rectangular glass of the Marumi ND4000 contains a metal frame on the sides, with a wide grip at the top and wavy edges at the side. This makes the filter easy to hold. Due to the magnetic grip you attach the filter to the holder easily, so you can use the filter instantly. The holder then grabs the filter firmly, so that no vignetting occurs. You can stack a total of three filters to the Filter Holder M100, which can be easily adjusted in height by the magnetic strip.
