NX Series 100x143.5mm Filter Frame

The aluminium frame secures 100mm by 143.5mm square filters for use with the NX Series holder. It protects filter edges and enables handling without touching the glass surface. Photographers using compatible Cokin Nuances filters will find this frame essential for the holder's slim profile and ultra-wide-angle lens clearance.

Installation uses the two supplied screws

The frame slides into the NX Series holder once the screws are fastened. A common issue is cross-threading the small screws if they are not aligned carefully before tightening. Ensure the filter sits flush inside the frame before final torque to avoid light leaks at the corners.

Under continuous field use the aluminium

The rigid frame maintains filter flatness during long exposures with ND8, ND64 or ND1024 densities. It also supports the Clearsky and Infrared 720 filters without warping. The design prevents vignetting on ultra-wide lenses even during extended shooting sessions.
