This 6-stop, 90mm Kase Magnetic ND Filter 90mm 6-Stop for K9 Holderis compatible with a Kase K9 100mm Filter Holder. Its 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without ovrexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the color of the image and are ideal for pairing with other filters.

Mounted within a non-threaded, steel filter ring, this filter is made specifically to fit within a separately available Kase 90mm Magnetic Lens Adapter Ring behind a Kase K9 100mm Filter Holder. Constructed from Schott B270 Superwhite glass for enhanced clarity and color fidelity, each glass surface includes multiple layers of anti-reflection coatings to prevent internal ghosting and reflections. These coatings also offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.
