Haida 72mm NanoPro Magnetic ND 0.9 3-Stop Filter

Precise 3-stop light control

The 72mm NanoPro Magnetic ND 0.9 filter delivers exactly three stops of neutral density reduction for photographers who need to open their aperture or slow their shutter in bright conditions without shifting colour balance. Its multi-coated optical glass suppresses reflections and glare while maintaining contrast across the frame. The magnetic mount locks on instantly and releases just as fast, so you can react to changing light without fumbling with threads.

Upgrade from screw-in ND filters

Photographers who currently thread individual ND filters will gain the ability to swap densities in seconds and stack up to four magnetic filters together for combined effect. The hardened nano coating resists water, oil, dust and fingerprints, reducing cleaning time between shots. Full compatibility with Kase and ICE Magco magnetic systems means existing magnetic filter collections work straight away.

Not for non-magnetic workflows

Lenses without a 72mm filter thread cannot use this filter directly, and the product ships without an adapter ring. Shooters who rely on variable ND flexibility will find the fixed 0.9 density limiting compared to adjustable alternatives. The magnetic system adds a thin profile that may vignette on ultra-wide lenses at their widest settings.

Fixed density limits creative range

The single 0.9 value means you must carry multiple filters to cover different lighting scenarios, unlike a variable ND that slides continuously. Stacking four filters increases total thickness and can introduce corner darkening on wide-angle glass. Magnetic attachment relies on the supplied adapter ring staying secured to the lens; losing that ring renders the filter unusable until replaced.
