Camera filter set K&F Concept ND8/ND16/ND32/ND64 + Polarizer for DJI Osmo Action 4

The K&F Concept Camera filter set for DJI Osmo Action 4 includes four neutral density filters (ND8, ND16, ND32, ND64) and a circular polarizer designed specifically for the Osmo Action 4 lens. These screw-on filters reduce incoming light to allow longer exposures and more consistent shutter control when filming or shooting stills in bright conditions, while the polarizer cuts reflections and enhances color saturation. The set is intended to improve motion blur control, smooth video capture, and dynamic range in outdoor and landscape photography without modifying the camera body.

Advantages

The neutral density filters provide graduated light reduction options that help achieve natural motion blur and correct exposure in high-luminance environments. The circular polarizer minimizes glare from reflective surfaces such as water and glass and increases contrast and color depth. Filters are matched to the Osmo Action 4 optical profile to preserve image quality, maintain sharpness and reduce the need for post-processing exposure adjustments. The compact set offers quick interchangeability for on-location shooting.

Suitable for

• Outdoor video recording in bright sunlight
• Landscape and nature photography
• Capturing smooth motion and controlled shutter speeds
• Reducing reflections on water, glass, and wet surfaces
• Timelapse and long-exposure effects with action camera

Key specifications

• Filter types: Neutral density (ND8, ND16, ND32, ND64) and circular polarizer
• Function: Light reduction for exposure control and polarization for glare reduction
• Compatibility: Designed for DJI Osmo Action 4 lens mounting system
• Construction: Multi-coated optical glass for improved light transmission and reduced flare
• Mount: Screw-on/clip-on design matched to the camera’s lens thread or adapter (specific adapter not included)

How to use

Select the ND filter appropriate for ambient light: ND8 for mild reduction, ND16/ND32 for stronger light, and ND64 for very bright conditions or when slower shutter speeds are required. Attach the chosen filter to the Osmo Action 4 lens according to the camera’s accessory mounting method, ensuring a secure fit and that the filter surface is clean. Rotate the circular polarizer while observing reflections in the viewfinder or on the camera screen until glare is reduced and color saturation reaches the desired level. Combine ND and polarizer as needed, taking care to maintain stable handling to avoid vignetting or unwanted rotation during recording.

Usage recommendations

Before shooting, clean filters with a soft microfiber cloth to avoid scratches and remove fingerprints. For video, set shutter speed to approximately double the frame rate for natural motion blur when using ND filters. Store filters in a protective case when not in use and change filters in a dust-free environment to minimize particles on the sensor or lens.
