SmallRig has introduced a family of magnetic Split Filter Kits built specifically for the dual-lens DJI Osmo Pocket 4P, using a two-piece design that covers both the wide and telephoto lenses in a single snap-on unit. Three kit configurations are available, spanning fixed ND, adjustable VND, CPL, and 1/4 Black Diffusion, with prices ranging from $45.99 to $49.99 and the ability to stack up to two filters at once.

The DJI Osmo Pocket 4P is a slightly different animal from previous Pocket models, and that has direct consequences for accessory makers. As we covered when DJI teased the two-camera pro version, the 4P pairs a 1-inch-type main camera with an added 3x telephoto camera on the same three-axis gimbal, which means any filter solution has to account for two lenses sitting side by side rather than one. SmallRig’s answer is a split, dual-aperture filter that clears both optical paths simultaneously while leaving gimbal rotation unobstructed.

A split design built around the dual-lens module

The defining feature here is the form factor. Each filter is a single piece with two openings, one for the wide camera and one for the telephoto, mounted onto a dedicated magnetic base. According to SmallRig, the split filter structure allows for quick installation and replacement, and the instant-on magnetic base lets you snap a filter into place without needing to remove it between shots. The company states the design fits the dual-lens system precisely and leaves gimbal rotation completely free, which is the practical concern for anyone shooting run-and-gun with a Pocket-style gimbal.

There is one workflow caveat worth flagging. SmallRig notes that stacking two filters should only be done while the camera is running, and that a single filter should be kept on the unit for power-on and power-off. That is a small operational detail, but it matters for anyone planning to build a two-filter stack into a fast shooting routine.

Three kits, three creative toolsets

SmallRig is offering the system in three configurations. The first pairs fixed ND16, ND64, and ND256 filters with a CPL. The second combines an adjustable VND1-5 with a CPL and a 1/4 Black Diffusion filter. The third bundles ND16, ND64, and ND256 with both a CPL and a 1/4 Black Diffusion filter, effectively the most complete of the three sets.

The VND1-5 filter can be adjusted by placing a finger into a small cutout and rotating the ring, giving between one and five stops of variable light reduction for changing conditions without swapping glass. The 1/4 Black Diffusion filter is aimed at softening highlights for a more cinematic feel, while the CPL handles reflections and glare. It is a familiar toolkit, adapted to an unfamiliar dual-lens layout.

Stacking and optical construction

Across all three kits, the headline flexibility is the ability to combine filters. Up to two filters can be used at the same time, which opens combinations such as ND plus CPL or ND plus Black Diffusion for layered creative control. This is where the magnetic base earns its place, since it allows a second filter to sit on top of the first without a threaded mounting step.

On the optical side, SmallRig claims the filters use multi-layer coated optical glass to achieve uniform light reduction, minimizing color shift and restoring natural, realistic picture colors. The company describes a concentric precision-bonding process with a multi-layer nano-vacuum coating, along with hydrophobic and oleophobic layers and a dual-layer anti-reflective coating on the substrate. These are manufacturer claims rather than independently measured results, and as always we would want to see filters like these tested against neutral references before drawing conclusions about color accuracy. Filmmakers who have followed our matte box coverage will recognize that SmallRig has been steadily expanding its filter and light-control lineup, and this Pocket-specific kit is a logical extension of that.

The filters are built from glass and aluminum alloy. The base measures 45.0 x 30.2 x 3.6mm / 1.8 x 1.2 x 0.1in, with ND and Black Diffusion elements at 44.1 x 19.3 x 1.9mm / 1.7 x 0.8 x 0.1in and the CPL and VND elements at 43.6 x 29.2 x 2.5mm / 1.7 x 1.1 x 0.1in. Depending on the configuration, product weight lands between roughly 97g and 106g / 3.4 and 3.7oz. Every kit ships with a dedicated filter base and a cleaning cloth.

This lands in a moment where magnetic, modular filter systems are gaining traction across the industry, something we saw recently with the Tilta Illusion Magnetic Filters aimed at larger cinema setups. SmallRig is applying the same snap-on logic to one of the smallest capable cameras on the market, and the two-camera Pocket 4P (with its headline 17-stop dynamic range claim from the main lens) is exactly the kind of tool where quick, gimbal-friendly light control pays off.

The three SmallRig Split Filter Kits for DJI Osmo Pocket 4P are available now. The ND16/64/256 and CPL kit is priced at $45.99, while both the VND1-5 with CPL and 1/4 Black Diffusion kit and the ND16/64/256 with CPL and 1/4 Black Diffusion kit are priced at $49.99. Further details are available on the SmallRig website.
