The NiSi Starter Kit for DJI Air 2S is a kit featuring two ND filters ND8, ND16, and an enhanced Polarizer designed for the DJI Air 2S. Each of these NiSi filters is designed with a lightweight airframe with Aircraft Aluminum Construction resulting in an amazingly light filter at approx 1g. These filters feature a high definition optical glass free from color cast which provides ultimate sharpness. These NiSi filters for DJI Air 2S are treated with NiSi’s Nano coating making them easy to clean, waterproof (the water beads up, and falls straight off) and very low reflection. These filters for DJI Air 2S are designed to complement the style of the DJI Air 2S and are easy to attach and remove from the camera. This Kit includes ND8 (3 Stop) ND16 (4 Stop) and Enhanced PL (Polarizer). Achieve more natural and refined videos expanding your creative possibilities. The ND filters lengthen the shutter speed by reducing the amount of light entering the camera – it gives a more natural sense of motion when filming. The ND filters feature the same IR technology available in NiSi's square filters to reduce color cast and allow a very true to life color.Polarizing FilterThe NiSi Enhanced Polarizer for DJI Air 2S helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
