Kase Armour K150P 150x150 square frame 2.0 ND filter

Kase Armour magnetic filter frame for square ND filters 150x150mm, 2mm thick.
You use the magnetic filter frame to use your square ND filters of 150x150mm with the Kase 150 Armour magnetic system. You simply place the filter in the magnetic frame and then attach it to the holder. The edges of the frame are finished in such a way that no light from the side and back enters the image. This prevents annoying reflections.
