Purpose & Audience
The Urth 100x100mm Square ND32 5-Stop Lens Filter Plus+ reduces incoming light by five f-stops using German B270 SCHOTT optical glass. It targets photographers and cinematographers who need precise exposure control in bright conditions for long exposures or wide apertures.
Fit & Exclusions
The standard 100x100mm square format suits filter holders built for that size. Buyers whose holders accept only circular screw-in filters or a different square dimension will need an alternative solution.
Sustained Behaviour
The 20-layer nano-coating maintains a consistent transmission curve during extended use, preventing colour shift. The durable glass and coating resist environmental wear, so optical performance remains stable across repeated shoots.

Questions about this item
What filter holder or adapter ring do I need to mount this 100x100mm square filter?
You need a 100mm square filter holder system or a 100mm adapter ring that matches your lens thread size; the filter itself has no built-in threads.
Will the German B270 SCHOTT glass introduce any colour shift when stacked with my existing ND or polarising filters?
The Plus+ range uses a 20-layer nano-coating designed for a consistent transmission curve and no colour cast, so stacking should preserve true colours.
How can I verify the filter is delivering a true 5-stop reduction after I fit it?
Meter a scene without the filter, add the ND32, and confirm the shutter speed lengthens by a factor of 32 (five full stops) at the same aperture.
