Puluz filter adapter mount for 52mm filters — accessory for GoPro Hero 9 Black

The Puluz filter adapter mount for 52mm filters is an accessory specifically designed to let GoPro Hero 9 Black users attach standard 52 mm screw‑in filters directly to the camera housing or compatible frame. It creates a stable, threaded mounting interface for neutral density, polarizing, and protective filters so users can better control exposure, reduce glare and reflections, and protect the lens during outdoor, action, or water-based shoots.

Advantages

This adapter mount provides a secure connection between 52 mm photographic filters and the Hero 9 Black, preserving framing and stability while allowing quick filter changes. Its threaded design keeps filters aligned and minimizes vignetting when using wide-angle lenses common to action cameras. The accessory is compact and lightweight, adding minimal bulk to the camera setup while enabling improved image control for landscape, action, and long‑exposure photography.

Suitable for

• Attaching neutral density (ND) filters for long‑exposure or motion blur effects
• Using circular polarizers to reduce glare and enhance contrast in water and sky shots
• Mounting protective UV or clear filters to shield the lens during outdoor activities
• Any GoPro Hero 9 Black setups where filter use is required, including housings or open frames that accept the adapter

Key specifications

• Filter thread size: 52 mm (female screw mount)
• Compatibility: Designed for GoPro Hero 9 Black camera housings or frames that accept front-mounted adapters
• Material: lightweight construction suitable for action use (plastic or polymer composite)
• Form factor: low-profile, screw‑in adapter that preserves wide‑angle field of view
• Mounting: threaded connection for standard screw‑in photographic filters

How to use

Align the adapter with the front of the GoPro Hero 9 Black housing or compatible frame and secure it according to the housing/frame instructions until it sits firmly and concentric with the camera lens. Thread a 52 mm screw‑in filter onto the adapter until it is snug; avoid overtightening. For rotating filters such as circular polarizers, adjust the filter while monitoring the image to achieve the desired effect. When using neutral density filters for longer exposures, pair the adapter with a stable mounting solution to minimize camera movement.

Usage recommendations

Use compatible 52 mm filters from reputable manufacturers to ensure proper fit and to avoid vignetting. Check that the adapter is fully seated and concentric with the lens before recording, and rinse and dry the adapter and filters after use in saltwater environments to prevent corrosion or grit build‑up.
