Purpose and user
The Urth 86mm Circular ND4 2-Stop Lens Filter Plus+ is built for photographers and cinematographers who need consistent 2-stop light reduction. It enables wider apertures and longer exposures in bright conditions without overexposure, preserving true colour fidelity thanks to professional-grade German SCHOTT B270 glass.
Build and mounting
The filter uses an ultra-slim magnalium rim designed to prevent vignetting on wide-angle lenses. Twenty layers of nano-coating protect the surface from water, oil and scratches while making cleaning easier. Double-threaded construction allows stacking with other 86mm filters or mounting a lens cap without removing the filter.
Deciding specification
The filter diameter is 86mm, so it only fits lenses with an 86mm front thread. Buyers whose lenses use a different thread size cannot use this filter without a step-up or step-down ring, which is not included.

Questions about this item
What filter thread size does the 86mm ND4 Plus+ fit?
It fits lenses with an 86 mm front thread, matching the diameter printed on the barrel.
How thick is the ultra-slim rim and will it clear a standard lens cap?
The ultra-slim rim is designed to prevent vignetting on wide angles and accepts a regular 86 mm snap-on cap.
How do I install the filter without cross-threading the double-threaded mount?
Align the filter squarely, turn gently until the threads engage, then rotate until snug — do not force it.
