K&F CONCEPT 6-pack Magnetic Filters for Pocket 4/3 – UV, CPL, ND16/PL, ND32/PL, ND64/PL, ND256/PL with Screen Protector

What it is and what it solves

This 6-pack from K&F CONCEPT is a set of magnetic filters designed for the Osmo Pocket 4/3. It includes UV, CPL, and six ND/PL combinations (ND16/PL, ND32/PL, ND64/PL, ND256/PL). The magnets are crafted to align with the lens base of the Pocket 4/3, enabling quick attachment and removal without removing the housing. If you value swift setup and reduced opportunities for lens handling, this kit aims to offer a practical upgrade to protected, better-controlled imagery.

Build quality and performance on paper

The filters use AGC optical glass, described as having high transmittance and reduced reflections from both the filter itself and glare. A 28-layer coating is intended to minimise reflections and flare, with claimed waterproofing, smudge resistance, and fingerprint resistance. In practice, this type of coating helps when shooting in bright light or near water, and should make cleaning easier between sessions.

What stands out

• Magnetic attachment designed for quick changes, which can be helpful when you’re moving between scenes.
• A dedicated UV filter and polarising options combined with a set of neutral density filters for exposure control, all in one pack.
• The inclusion of a tempered screen film offers additional protection for the screen of the Osmo Pocket, which is a thoughtful pairing for a travel kit.

Limitations and what to watch for

• The description specifies the filters are for Pocket 4/3, if your setup deviates from that model, confirm compatibility before purchasing.
• The impact of ND values depends on lighting and the sensor’s dynamic range, you may need to adjust exposure and white balance to maintain natural skin tones and colours.
• As with any multi-filter kit, there is a risk of mounting misalignment if the magnetic interface isn’t seated properly, take a moment to align each filter carefully.

Who it’s for

This kit is suited to mobile filmmakers and photographers who use the Osmo Pocket 4/3 and want a compact, all-in-one filter solution for landscape, architectural, or travel shoots where quick transitions are helpful and you want additional control over glare and exposure.

Who it isn’t ideal for

If you rely on the absolute maximum optical performance from a single high-end filter or require specific filter diameters or resolutions not covered by this 6-pack, you might find the options limiting. Also, if you work in highly variable or extremely challenging lighting, you may still need to stack filters or use higher-end glass beyond what a compact kit offers.

When it makes sense to buy

• You prioritise convenience and portability in a single carry kit.
• You frequently shoot in bright conditions or near reflective surfaces where glare is an issue.
• You want a basic setup for ND control and polarisation without swapping multiple competing filter systems.

When to pass

• You need the absolute highest optical quality from filters and are prepared to invest in dedicated, non-magnetic filter systems.
• You require specific filter sizes or professional-grade colour fidelity beyond a compact 28-layer coated glass solution.

What to check before buying

• Confirm compatibility with your Osmo Pocket 4/3 configuration and any protective housings you use.
• Consider how you will manage cleaning and maintenance to keep the 28-layer coating effective over time.
• Verify that the six filters cover the exposure scenarios you expect to encounter in your usual shoots.

Practical use example

Imagine capturing a seaside sunset with the ND256/PL engaged to keep shutter speeds reasonable while the CPL helps control sky reflections. Swapping to the ND16/PL allows a brighter midday scene to be captured with reduced glare as you move along the coastline, all without fiddling with bulky gear.

FAQ

• How easy is it to attach the filters? The magnets are designed for quick attachment to the Pocket 4/3’s lens base, enabling faster changes between scenes.
• Do the coatings affect colour accuracy? The 28-layer coating aims to reduce reflections and flare, this should help maintain image clarity, though some workflows may notice subtle differences when using stronger ND values.
• Is the screen protector sturdy? The tempered film is intended to protect the screen from bumps and scratches, but treat it like a screen protector and inspect it after drops or heavy use.

Decision – Is it worth it?

Is it worth it? If you value portability, quick filter changes, and a bundled set to cover common exposures for Osmo Pocket 4/3, this 6-pack offers practical utility. It may not replace premium, purpose-built filters for critical colour work, but it provides a coherent, affordable route to better control and protection in everyday shooting.
