Irix Edge ND16 Neutral Density Filter 86mm - 4-Stop Light Reduction, Multi-Coated Optical Glass, Slim Aluminum Frame

Cut light by 4 full stops with the Irix Edge ND16 86mm filter, built around premium Schott B270 optical glass and a multi-layer NANO coating that repels water, oil, and scratches while preserving true-to-life colour neutrality. Whether you're chasing silky waterfalls in broad daylight or shooting wide open at f/1.4 for razor-thin depth of field, this slim-profile neutral density filter gives you the creative headroom to slow the shutter or widen the aperture without overexposure.

Overview

The Irix Edge ND16 is a circular neutral density filter with a 86mm thread, engineered for photographers and videographers who demand consistent, high-quality results. Its ND16 rating corresponds to a 4-stop light reduction (optical density 1.2, 6.25% transmittance), making it ideal for long-exposure landscape work, architectural shots with moving clouds, or capturing motion blur in bright conditions. The filter's double-threaded aluminium frame allows stacking with other filters or attaching a lens cap, while the low-profile design minimises vignetting on wide-angle lenses.

What stands out

• 4-stop neutral density (ND16) for long exposures and wide apertures in bright light
• Schott B270 optical glass with multi-layer NANO coating: anti-reflective, hydrophobic, oleophobic, and scratch-resistant
• True colour neutrality – no perceptible colour shift, preserving image fidelity
• Slim, lightweight aluminium frame with double threading for stacking and cap compatibility
• 86mm diameter fits a wide range of professional lenses
