K&F Concept ND/PL Filters for DJI Osmo Action 4/5 Pro – 4-Pack

What it is

This is a 4-pack of real ND/PL filter sets designed for the DJI Osmo Action 4 and Action 5 Pro. Each kit includes ND8&amp,PL, ND16&amp,PL, ND32&amp,PL and ND64&amp,PL filters. They’re built to be lightweight and easy to attach, with a threaded mount that fits the camera’s lens without fuss.

What problem it helps solve

If you’re shooting outdoors in bright light, the ND filters reduce the amount of light entering the sensor, allowing you to use slower shutter speeds for smoother motion. The PL (polarising) element helps cut reflections from non-metallic surfaces like water or glass, and can also tame glare in outdoor scenes. In short, you get more cinematic motion and clearer colours when the sun is bright.

How the build holds up in practice

These filters use high‑grade AGC optical glass, which aims to deliver clear images with minimal distortion. The manufacturer also highlights a 28‑layer multi‑coat system intended to curb reflections and maintain colour accuracy and contrast across the board. The result on paper is clearer skies, more natural skin tones, and less colour shifting in high-contrast scenes.

What stands out day to day

• The 4‑pack covers a spread from moderately bright to very bright conditions with ND8, ND16, ND32 and ND64 options.
• The 2‑in‑1 design integrates ND and PL, reducing glare while managing exposure in a single pass.
• A robust threading system aims to deliver a secure fit without frequent adjustments.
• The balance between weight and performance is noted as suitable for action camera setups where you don’t want extra load or wobble.

What might not be perfect

If you’re after a lightweight, budget‑friendly kit, this set appears competitive, but you should consider whether the Osmo Action’s dynamic range is best served by these specific ND steps. Some users may prefer a different progression of ND strengths for frequent changes in lighting. Also, the description focuses on what the kit contains and generic performance claims, field results can vary with lighting, filters’ alignment, and post‑processing.

Who it’s for

• Creators who shoot outdoors with an Osmo Action 4 or 5 Pro and want more control over exposure and glare without swapping lenses.
• Filmmakers aiming for smoother motion in bright scenes and more natural colour in reflective environments.
• Beginners who want a single, simple accessory kit to cover common daylight scenarios.

Who it isn’t ideal for

• If you rely on ultra‑wide dynamic range in extremely harsh light, or if you need very fine ND steps beyond ND8/16/32/64, you might find the set limiting.
• If you already own higher‑end filters with more aggressive coatings or different step sizes, you may prefer to mix and match to your preferred workflow.

When does it make sense to buy

• You frequently shoot outdoors in daylight with an Osmo Action 4/5 Pro and want a practical, ready‑to‑go filter kit.
• You value glare control from PL together with exposure reduction from ND, in one compact package.
• You prefer a lightweight solution that won’t noticeably affect the camera’s balance or gimbal performance.

When to hold off

• If you rarely shoot in bright light or have alternative stabilised lighting setups, the investment may be marginal.
• If you expect niche colour fidelity improvements or need more exotic ND configurations, this kit may feel basic.

Things to check before buying

• Compatibility with DJI Osmo Action 4 and 5 Pro (as stated).
• Ensure you’re comfortable with the four filters in the pack and their ND strengths.
• Consider whether you need a separate case or pouch for protection and transport.

Practical hint: a moment in use

Imagine a bright lakeside scene: you twist on ND64 to drop light and slow the shutter, while the PL element helps cut glare off the water, so the reflections don’t overpower the sky. The result should be smoother water motion with more accurate colours, without overexposing the highlights.

FAQ

• Do these filters introduce noticeable colour shift? They emphasise maintaining colour accuracy through multi‑coating, but some shift is possible depending on lighting and camera settings.
• Will the PL always cut glare equally on water and glass? PL performance varies with angle and surface, it’s generally effective outdoors but not a universal cure-all.
• Are they easy to remove when not needed? The threaded design is intended for straightforward attachment and removal, though you’ll want to handle them carefully to avoid fingerprints.

Is it worth it?

A solid pick if you prioritise practicality, lightweight design and a straightforward 4‑filter set to handle common daylight scenarios. It may not be the best fit if you chase extremely precise ND steps or require specialised filtration for niche shoots.
