This 3-stop Armour Magnetic Circular ND Filter from Kase features a magnetic circular design for the Armour 100mm Magnetic Filter Holder. It is quickly and easily installed to reduce the amount of light captured in making an image. This provides greater control over depth of field, or when lengthening shutter speed to add blur.
This filter has a 95mm diameter and magnetically attaches to the Armor Magnetic filter holder. It is made of toughened optical glass with a metallic nano coating to resist showing any color caste. It also features resistance coating that makes it water, dust, and dirt repellent for easy cleaning. This tough finish also makes it scratch resistant, making it great for coastal photography, harsh environments, and terrain where ordinarily resin and glass filters are susceptible to issues.
This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.
