K&F CONCEPT FSD01 Filters Kit for DJI Osmo Pocket 3/4 – 4-Pack with Magnetic CPL, Wide Angle, ND2-32 and Black Diffusion 1/4

What it is and what it solves

The K&F CONCEPT FSD01 is a 4-pack magnetic filter kit designed for the DJI Osmo Pocket 3 and 4. It includes a Wide Angle Lens, a CPL, an ND2-32, and a Black Diffusion 1/4 filter. Built with AGC optical glass and a 28-layer nano-coating on both sides, the set is aimed at expanding shooting options while helping with glare, exposure, softening skin texture, and overall contrast. On the surface, it offers a straightforward way to broaden the pocket-sized camera’s capabilities without swapping lenses. However, as with any add-on kit, real-world results depend on how you use it and the lighting you’re working in.

How it fits into daily shooting and why it matters

The FSD01 broadens the field of view by adding a magnetic Wide Angle Lens, increasing the FOV to around 112°. That can be useful for travel or tight indoor spaces where you want to capture more of the scene in a single frame. The CPL seeks to reduce non-metallic reflections off water or glass and to enhance colour saturation and contrast, which helps in landscapes or reflective surfaces. The ND2-32 is a variable neutral density option, giving 1–5 stops of light reduction to control motion blur in brighter conditions. The Black Diffusion 1/4 softens skin texture and adds a film-like glow, which some scenes may prefer for a more cinematic look.

What stands out and where it may fall short

On the plus side, you get a compact array of filters with real tactile magnetism for quick changes, a feature that can save time on shoots. The use of imported AGC glass and hydrophobic, dust-repelling coatings is sensible in mobile photography contexts. The downside is that the wider option, the Wide Angle Lens, can introduce distortion or vignetting if used in tight frames or at the edges of a wide shot, and the ND range is fixed in a compact dial rather than a more granular system. It’s not a comprehensive upgrade kit, it’s a practical add-on for everyday scenes rather than a replacement for a dedicated camera setup.

Who it’s for

This kit should appeal to hobbyists or creators who frequently use the Osmo Pocket 3/4 for travel, vlogging, or casual landscape work and want a quick way to vary exposure, contrast, and field of view without swapping gear. If your priority is ultra-clean wide landscapes or controlled deep stops in very bright sun, you may want to assess whether the 1–5 stops of the ND2-32 coupled with the diffusion effect aligns with your typical lighting.

Who it isn’t perfect for

If you’re chasing super-clean landscape shots with pristine edge-to-edge sharpness and minimal distortion, or you rely on precise, granular ND control, this kit may feel a step behind more modular options. Also, the packaging note indicates compatibility with Pocket 3/4, but some buyers may encounter minor confusion about wording on older proofs—the contents are the same, yet the label might read differently.

When it makes sense to buy

Consider this kit if you want an all-in-one, ready-to-use filter set that covers basic to mid-range adjustments: glare reduction, mild softening for portraits, light control through ND, and a wider framing option for travel or environmental shoots. If you value convenience, quick changes, and a bundled price over chasing individual high-end filters, this kit offers straightforward value.

What to check before buying

• Verify you’re comfortable with the Wide Angle increase and the potential edge distortion in certain compositions.
• Consider whether the 1–5 stop ND range suits your typical outdoor brightness levels.
• Note that the packaging may state Pocket 3, contents and compatibility remain with Pocket 4 as well.
• Look after the coatings and glass by cleaning with soft materials to preserve spray resistance and coating integrity.

How it compares to other approaches

For casual shooters, having a magnetic filter system built for Osmo Pocket 3/4 is more convenient than carrying separate screw-in filters or a larger filter kit. If you already own a dedicated mirrorless or action camera with built-in ND and CPL options, you’ll likely notice the differences in image quality, field of view, and colour handling when using mobile-centric filters. This kit prioritises portability and ease of use over absolute optical performance.

Is it worth it?

• If you want a compact, all-in-one filter kit for the Osmo Pocket 3/4 that covers wide-angle, polarisation, light reduction, and skin-softening effects, it’s worth considering.
• If your aim is to extract top-tier optical performance with precise control and minimal compromise, you might want to compare individual filters or alternative setups.

FAQ

• Will the filters fit Osmo Pocket 3 and 4 interchangeably? Yes—the kit is designed for both Pocket 3 and Pocket 4 devices.
• Does the ND filter offer exact stops anywhere in between 2 and 32? The ND is described as ND2-32 (variable), providing 1–5 stops of light reduction, with the exact stop depending on the dial position.
• Is there any special care required for the coatings? The filters use hydrophobic, dust-repelling coatings intended to make cleaning easier, avoid abrasive cleaning and use soft cloths.

Final decision

Is it worth it? If you want a practical, portable upgrade for everyday Osmo Pocket 3/4 use, this kit provides a balanced mix of convenience, versatility, and modest optical enhancement that can justify the cost for many shooters.
