Neutral Density Filter ND4 (Full) for DJI Osmo Action by Greenl — model SB5301

The Neutral Density Filter ND4 (Full) for DJI Osmo Action by Greenl is a full-frame gray filter designed to reduce incoming light by two stops. It is made to fit DJI Osmo Action cameras and helps control exposure in bright conditions, enabling wider apertures or slower shutter speeds without overexposure. The ND4 filter is suitable for outdoor action and sports videography, landscape shooting, and time-lapse sequences where managing light and motion blur is important.

Advantages

This ND4 full-frame filter provides consistent light reduction across the image, minimizing the risk of overexposure while preserving color neutrality and minimizing color cast. It allows for smoother motion rendition by enabling slower shutter speeds and helps achieve shallower depth of field when shooting in bright light. The filter is designed for secure attachment to the DJI Osmo Action camera and is durable enough for frequent outdoor use.

Suitable for

• Action and sports videography in bright daylight
• Time-lapse sequences with controlled exposure
• Landscape and outdoor filming where motion blur or wider apertures are desired
• Handheld shooting to reduce harsh highlights and glare

Key specifications

• Filter type: Neutral Density (ND4) — two-stop light reduction
• Coverage: Full-frame for compatible action camera lens
• Optical effect: Reduces light uniformly to allow wider aperture or slower shutter speed
• Color balance: Neutral gray to minimize color shift
• Intended camera: DJI Osmo Action compatible mount and size

How to use

Attach the ND4 filter to the front of the DJI Osmo Action camera according to the camera and filter mounting instructions, ensuring a secure fit before powering on the camera. Use the filter when shooting in bright daylight to prevent overexposure while allowing wider aperture settings or slower shutter speeds for smoother motion or creative depth-of-field effects. Check framing and exposure after mounting and adjust camera ISO, aperture, or shutter speed as needed to achieve the desired result.

Usage recommendations

For best results, use the ND4 filter outdoors in moderate to bright light conditions; combine with manual exposure controls or shutter-priority modes when available. Inspect and clean the filter surface with a soft, lint-free cloth before use to avoid artifacts, and store the filter in a protective case when not mounted.
