A combined variable neutral density and polarizer using PolarPro's Chroma Glass to minimise color shift, available in 2-5 stop (and 6-9 stop) variants and select mist versions. It features independent bi-rotational control for ND and polarization, haptic stop detents, and Defender 360 protection, suited for outdoor photo and video work requiring glare control and exposure reduction. Ideal for photographers and filmmakers wanting fewer stacked filters and neutral color rendering.

Firecrest Ultra IRND are hyper-neutral coated round ND filters available in many thread sizes and densities designed to suppress near-IR while maintaining accurate color balance. They use a rare-earth metal IRND coating on high-quality glass with anti-reflective and hydrophobic finishes, suited for long-exposure and cinematic use. Available densities range from 1 stop up to 16 stops for strong light reduction.

The kit contains four Firecrest solid neutral density glass filters with Firecrest multi-coating and IR attenuation, offering highly neutral color performance for long exposures. It's built for use with 85mm holders and targets landscape and long-exposure photographers seeking minimal color cast and durable coatings.

High-end cinema ND kit containing three Firecrest Ultra solid neutral density filters (1.2, 1.5, 1.8 OD) delivering 4-, 5-, and 6-stop exposure reductions with rare-earth IRND coating and multi-coated Schott glass for neutral color performance across UV, visible and infrared. Suited for professional filmmakers using matte boxes and large-format filter holders who need color-neutral, low-IR NDs for controlled exposure and consistent color rendering.

A combined variable neutral density and circular polarizer designed for the Helix MagLock system with Chroma Glass for minimal color shift and separate ND and polarizer control; includes defenders and requires Helix base plates. It offers tactile stop detents, multi-resistant coatings, and is stackable with other Helix frames. Suited for cinematic shutter speeds and quick magnetic quarter-turn mounting.

Premium Peter McKinnon edition variable ND with Cinema/Chroma series glass, preset stop ranges (2-5 stop), haptic feedback ring, and Defender 360 case; designed to avoid X pattern cross-polarization and to resolve high-resolution sensors. Suited for photo and video shooters who need smooth, repeatable exposure control and high color fidelity.

Thin 2mm cinema-grade IRND glass available in individual densities and kits; uses Firecrest IRND coating for neutral color and reduced infrared contamination while keeping weight low for drones, gimbals, and lightweight matte boxes. Available as single-sheet 4x5.65in filters or multi-filter kits with tray options, suitable for professional cinematography needing lightweight, high-quality ND filtration.
