The Kase Armour System incorporates round 95mm magnetic filters that fit into the round opening of the filter holder. The round magnetic filters can be rotated with a cog wheel on the filter holder, allowing you to use the magnetic filters independently of the 100mm filters.
The Master Kit includes three 95mm magnetic filters; a Circular Polarizer and two ND filters (ND 1.8 6-stop and ND 3.0 10-Stop).
The kit also includes three 100mm Magnetic Grad ND filters (Soft 0.9, Soft 1.2, and Reverse 0.9) that attach to the holder with the included 100x150mm magnetic filter frame. Two step up adapter rings (67-82mm and 72-82mm) as well as a 77mm and 82mm adapter rings allow you to use the Armour filter kit on a wide variety of lenses.
Please Note: Armour is not Compatible with Kase K9, Wolverine or Skyeye Magnetic Filters.
