Learn how to install the GoTough Naked Filter Adapter on a GoPro HERO3 without a housing, then add screw-on filters for controlled exposure and protection.
Quick answer
Use the Fotodiox Pro WonderPana Go H3 Naked Filter Adapter to mount screw-on glass filters directly on a bare GoPro HERO3 (not HERO3+). The adapter attaches without a housing, so you can add filters for exposure control or lens protection while keeping the camera's normal functions accessible.
Why go case-free with a HERO3
Shooting without the standard housing reduces bulk and avoids reflections or scratches on the housing window. It also gives you direct access to the lens for cleaning. The trade-off is that the bare lens has no filter threads and limited protection, which is exactly what the WonderPana Go H3 adapter solves.
This adapter is specific to the HERO3 Naked camera, not the HERO3+. If you use a HERO3+ or any other model, check compatibility before installing; forcing the adapter can damage the mount or the camera.
When a case-free filter setup makes sense
A case-free setup is best for controlled environments where you want to use neutral density or polarizing filters without housing interference, such as time-lapse or long-exposure shots. It is not ideal for underwater or high-impact action, where a waterproof housing is still necessary. Also, because the adapter is all-metal, it adds a small amount of weight and rigidity to the front of the camera; handle the camera carefully when mounted on a suction cup or clamp.
Step-by-step installation
- Power off and clean the camera: Turn off the GoPro HERO3 and wipe the lens and front bezel with a microfiber cloth to remove dust or fingerprints. A clean surface prevents grit from getting trapped under the adapter. Check for dust before mounting; trapped particles can scratch the lens.
- Align the adapter with the lens: Hold the adapter so its opening lines up with the camera lens. The adapter is designed to fit the HERO3 Naked body; do not force it onto a HERO3+ or other model. Confirm you have a HERO3, not a HERO3+, before pressing the adapter into place.
- Press the adapter firmly onto the camera: Push the adapter straight onto the front of the camera until it seats evenly around the lens. The all-metal construction should provide a solid, snug fit without wobble. If the adapter feels loose or uneven, remove it and re-align; do not use excessive force.
- Screw on your chosen filter: Thread a compatible glass filter onto the adapter's front threads. Turn clockwise until it is hand-tight; do not over-tighten, as this can make removal difficult. Start with a filter that matches your lighting; for bright sun, try a neutral density filter to control exposure.
- Test camera functions: Power on the camera and check that buttons, ports, and the lens are unobstructed. Take a few test shots to confirm the filter does not cause vignetting or interfere with the field of view. Review test shots on a larger screen if possible; small vignetting may be hard to see on the camera LCD.
- Remove the adapter when not in use: To remove, gently pull the adapter straight off the camera. Avoid twisting, which could stress the mount. Store the adapter and filters in a padded case. Remove the adapter before packing the camera to prevent accidental leverage on the lens area.
