Square ND32 filter for bright-light control

The Urth 75x85mm Square ND32 5-Stop Lens Filter Plus+ cuts five f-stops of light, giving photographers and cinematographers creative control over long exposures and depth of field in bright conditions. German B270 SCHOTT optical glass with 20 layers of nano-coating delivers true colour rendition and consistent transmission. The coating also repels water, oil and scratches for easier maintenance.

Steps up from lighter ND filters

This filter replaces weaker neutral-density options when you need stronger light reduction for extended shutter speeds or wider apertures without overexposure. The jump is worth it when a 3-stop or 6-stop filter cannot hold highlights in harsh sunlight or when cinematic motion blur demands the specific 5-stop density. The Plus+ coating improves durability over uncoated or lightly coated glass.

Check your filter holder and lens thread

Verify that your square filter holder accepts 75x85mm sheets before ordering. Confirm the holder mounts securely to your lens diameter or adapter ring to prevent light leaks. Ensure your workflow can accommodate square filters rather than circular screw-in types, as this format requires a compatible holder system.

Questions about this item

Does the 75x85mm size fit standard square filter holders?

Yes, the filter is described as a standard fit for 75x85mm square filter holder systems.

How do I install the filter without leaving fingerprints on the coated glass?

Hold the filter by its edges, align it with the holder slots, and slide it in gently; the 20-layer nano-coating repels oil but skin contact should still be minimised.

How should I clean the nano-coating when it gets dusty or smudged?

Use a blower to remove loose particles, then wipe lightly with a microfibre cloth and optical cleaning fluid; the 20-layer nano-coating resists water, oil and scratches.
