SmallRig ND Filter Kit for DJI Osmo Action 5 Pro/Action 4 - 5 Pack

Our review of the SmallRig ND Filter Kit for DJI Osmo Action 5 Pro/Action 4 finds it best suited to vloggers and action shooters who want simple, reliable exposure control and reflection reduction without changing lenses. The kit's single biggest advantage is its snap-on convenience combined with high-quality optical glass and multi-coating, which together preserve color accuracy while cutting glare and excess light. For anyone who needs quick ND stops and a polarizer that work seamlessly with the Osmo Action series, this kit brings practical control in the field.

Key Features

• Four-filter set: Includes a CPL and three fixed-stop FS ND filters (ND8, ND16, ND32) to cover bright to very bright shooting conditions for balanced exposure and creative long exposures.
• Full-spectrum filtering: The filters reduce light evenly across wavelengths to minimize color casts and keep footage looking true-to-life.
• Snap-on design: Quick-attach mounting lets users install filters without removing the camera lens, saving time during shoots.
• Optical glass with nano coating: Multi-layer coatings on both sides improve color fidelity and provide water- and oil-resistance for easier cleaning.
• Protective silicone cover: A soft lens cover is included to protect the camera lens from scratches during storage and transport.
• Durable construction: Strong chemical stability in the materials helps filters hold up under demanding outdoor conditions.

Who It's For

The kit is ideal for Osmo Action 5 Pro and Action 4 users who shoot outdoors, including adventure vloggers, landscape filmmakers, and sports videographers who need quick ND stops and polarization without fidgeting with threaded mounts. Its snap-on convenience suits fast-paced environments where changing lighting requires rapid adjustments.

Users who require variable ND control, specialty cinematic filters beyond ND8/16/32, or who prefer screw-mounted filters for other camera systems should look elsewhere. This set is designed specifically for the Osmo Action form factor, so it is not a universal solution for larger rigs.

Pros & Cons

Pros

• Five-piece kit gives essential ND steps plus a CPL for versatile exposure and reflection control.
• Multi-coated optical glass maintains strong color accuracy and resists water and oils for easier maintenance.
• Snap-on mounting is fast and practical for action shooting without removing the lens.
• Included silicone cover protects the camera lens when filters are not in use.

Cons

• Fixed-stop NDs limit fine-grain exposure adjustment compared with variable ND systems.
• Designed specifically for Osmo Action 5 Pro/Action 4 so compatibility is limited to those models.

Frequently Asked Questions

Will these filters fit my Osmo Action 4?
Yes, the kit is specified for both DJI Osmo Action 5 Pro and Action 4 models and uses a snap-on mount designed for those cameras.

Can the CPL be used underwater?
The CPL reduces surface reflections and can help with water clarity when shooting above water, but it is not intended for prolonged submersion; the coatings improve moisture resistance but do not make the filter waterproof.

Do the filters affect color accuracy?
The kit uses full-spectrum filtering and multi-layer coatings to minimize color casts and preserve true-to-life colors in footage.
