The Top Pick for Most Creators: SmallRig Split Filter Kits
Modular filter systems are interchangeable optical tools—such as ND, CPL, and diffusion filters—that stack, drop in, or snap onto a camera to give filmmakers professional optical control without bulky rigs. For most compact and mobile filmmakers, the SmallRig Split Filter Kits for DJI Osmo Pocket 4P are the standout choice, because they deliver stackable ND, variable ND, CPL, and diffusion in a fast snap-on package built for a pocket gimbal camera. These compact camera filters use a dual-aperture plate that covers both the wide and 3x telephoto lenses in one click-on unit, keeping the three-axis gimbal free to rotate. SmallRig offers three kits spanning fixed ND16/64/256, an adjustable VND1–5, CPL, and 1/4 Black Diffusion, with prices from USD 45.99 (approx. ₱2,600) to USD 49.99 (approx. ₱2,800). You can stack up to two filters at once for layered creative control over exposure, reflections, and highlight softness.
Why SmallRig’s Stackable Filters Unlock Pocket Gimbals
SmallRig’s snap-on split design is purpose-built for the dual-lens DJI Osmo Pocket 4P, with two openings aligned to the wide and telephoto modules on a single magnetic base. That means you do not have to swap tiny filters every time you change focal length, and the gimbal remains unobstructed for run‑and‑gun moves. The VND1–5 plate gives 1–5 stops of variable ND via a small cutout ring, so you can dial exposure for changing light without touching shutter speed or ISO. Across the range, SmallRig uses multi‑layer coated optical glass to keep light reduction uniform, minimize color shift, and maintain natural-looking colors. You can combine ND plus CPL or ND plus 1/4 Black Diffusion in a two‑filter stack, which turns this tiny camera into a flexible, on‑the‑move cinema tool. According to SmallRig, the split filter structure allows quick installation and replacement while keeping the system gimbal‑friendly.
Electronic ND for High-End Rigs: KipperTie LCcineND
If you are building around a matte box and want the cleanest variable exposure control available, go straight to the KipperTie LCcineND. This is a non‑polarising electronic ND filter sized for a single 4×5.65" matte box tray, with an ND range from 1.5 to 5 stops and remote control via smartphone app or follow focus motor. Electronic ND filters avoid the cross‑polarisation artifacts that can plague traditional two‑polariser variable NDs, because there are no moving optical elements in the glass. KipperTie states that the LCcineND maintains excellent color accuracy and consistency at all strengths, with only a small magenta shift compared to no filter. It is enclosed in a CNC‑machined aluminum frame for durability and fits any industry‑standard 4×5.65" matte box. The LCcineND is available for about £1,750 (roughly USD 2,340 / approx. ₱132,000), reflecting its role as a serious professional tool.
Lens and Filter Modularity: MOFAGE POCO II Drop-In Filter Mount
For mirrorless cinema bodies that swap between many lenses, the MOFAGE POCO II is the smartest way to add a drop-in filter mount and modular lens support. The adapter keeps the modularity of the original POCO, but now adds an interchangeable PL/EF front lens mount, more clearance for lenses with longer rear elements, and a lighter, more compact build. On the camera side, POCO II keeps a modular mount system compatible with Sony E, Canon RF, Leica L, Nikon Z, FUJIFILM X, and KineMOUNT. The first‑generation POCO started life as a budget‑friendly PL adapter with an integrated drop‑in variable ND and has grown into a full ecosystem with new filters and camera mounts. According to the manufacturer, POCO became one of the most interesting alternatives to a front matte box, and POCO II extends that idea with cross‑compatible components and new second‑generation VND, clear, CPL, and effects filters for lenses with longer protrusions.
Buy if / Skip if
- Buy the SmallRig Split Filter Kits if you shoot primarily on the DJI Osmo Pocket 4P and want compact camera filters that snap on fast and stack ND, VND, CPL, and diffusion in one dual-lens plate.
- Skip the SmallRig Split Filter Kits if your main cameras do not use the dual-lens DJI Osmo Pocket 4P form factor, since these split filters are built specifically around that module.
- Buy the KipperTie LCcineND if you run a 4×5.65" matte box and need non-polarising electronic ND filters with 1.5–5 stops of remote-controllable exposure adjustment and strong color consistency.
- Skip the KipperTie LCcineND if your work does not involve matte boxes or if you do not need electronic ND control in a single 4×5.65" tray.
- Buy the MOFAGE POCO II if you want a modular drop-in filter mount that adapts mirrorless bodies to PL or EF lenses and supports a growing ecosystem of variable ND, clear, CPL, and effects inserts.
- Skip the MOFAGE POCO II if you never adapt lenses across mounts or do not need an interchangeable PL/EF front combined with a modular camera-side system.
