Neutral Density Filter Mounts
The LBTEK Neutral Density Filter Mount NDFR-PM allows for the any round continuous or step-type ND filter onto a rotating axis. It comes with an M6 threaded hole for connection to a 12.7 mm post. The mount enables 360° rotation of the filter in free space, and this minimizes the impact on the clear aperture of the neutral density filter. Each mount includes an M6 to M4 threaded hole adapter.
