K&F Concept UV CPL ND4 Filter Kit for Insta360 GO 3S

What matters most

This 3‑pack from K&F Concept is designed specifically for the Insta360 GO 3S action camera, providing UV, CPL and ND4 filters to cover common everyday shooting scenarios. On paper, it aims to protect the lens while offering practical enhancements to colour balance, glare control and exposure. It’s meant for users who want a simple, modular set to handle bright days, reflective surfaces and motion blur in one compact kit.

Technical overview

The filters use imported AGC optical glass with multi‑layer coatings on both sides, which helps to minimise glare and flare and to preserve image colour. The kit includes UV, CPL and ND4 filters, each serving a distinct purpose: UV to reduce ultraviolet haze, CPL to cut reflections from non‑metallic surfaces, and ND4 to allow longer exposures in bright light. The frame is made from aviation aluminium alloy and the filters thread onto the camera, aiming for a snug fit with straightforward installation and removal.

What stands out

One practical aspect is the 3‑pack approach. For casual or semi‑pro use, you can swap between UV for general protection, CPL for landscape or water scenes, and ND4 for motion or night‑style effects without needing separate purchases. The lens protection angle is reinforced by the multi‑layer coatings, which are intended to keep the glass resilient against scratches, dust and oil.

Practical use and limits

If you frequently shoot outdoors on bright days or near reflective surfaces, you’ll likely appreciate the ability to adapt quickly with a single purchase. However, it’s worth noting that the exact optical outcomes depend on the lighting and how well the filters are cared for. The kit is positioned as an accessory rather than a complete photography solution, so it’s sensible to pair it with your existing go‑to settings and workflow.

Who it’s for and who it isn’t for

This kit suits vloggers, hobbyists and travellers who want a lightweight, dedicated filter set for the Insta360 GO 3S without juggling multiple separate filters. It may not be the best option if you routinely shoot in very variable or professional lighting conditions requiring more specialist glass or higher ND values.

What to check before you buy

• Confirm that your Insta360 GO 3S body is compatible with threaded filter attachments.
• Consider how often you’ll use each filter type and whether you need additional filtration options beyond UV, CPL and ND4.
• Inspect the coating and frame for smooth threading and a secure fit to avoid light leaks or mounting issues in active use.

In context with alternatives

Compared with a generic, single‑purpose filter, this 3‑pack offers a middle‑of‑the‑road balance: it’s modest in price but provides three core tools for everyday filming. If you expect to push for more dramatic ND effects or require higher precision polarisation, you might look for higher‑end options or larger ND values. For many day‑to‑day Insta360 GO 3S users, this kit can deliver practical value without overextending the budget.

Final buying decision

Final verdict: If you prioritise a compact, ready‑to‑use filter set to cover protection, glare control and light management for casual footage, this K&F Concept 3‑pack is worth considering. It’s not a premium, professional glass upgrade, but it aligns with a practical, no‑nonsense approach to improving everyday footage. Be mindful of handling and storage to preserve coating and threading quality over time.
