Neutral Density Adjustable Fader Filter ND32–512 for DJI Osmo Action 3/4/5 Pro — K&F SB10088

The K&F SB10088 Neutral Density Adjustable Fader Filter ND32–512 for DJI Osmo Action 3/4/5 Pro is a variable ND filter designed for action camera housings and mounts. It provides continuous light attenuation from approximately 5 to 9 stops (ND32–ND512) to help control exposure and motion blur in bright outdoor conditions. The filter is intended to maintain desired shutter speeds and frame rates when filming fast motion, enabling smoother motion portrayal and creative long‑exposure effects while using DJI Osmo Action 3, 4, and 5 Pro cameras.

Advantages

The adjustable fader design delivers seamless transition across a wide ND range without changing filters, allowing precise exposure control. Its construction is optimized for action camera housings and secure mounts, reducing the need to open or modify waterproof casings. By enabling consistent shutter speeds, the filter helps minimize rolling shutter and stutter when capturing high‑speed footage and supports creative control over motion blur and depth of field appearance in daylight shooting.

Suitable for

• Outdoor action sports filming in bright sunlight
• Capturing smooth motion and reducing stutter at high frame rates
• Creating long‑exposure effects such as blurred water or streaking light
• Use with waterproof housings and mounted rigs for biking, surfing, or motor sports

Key specifications

• Variable attenuation range: ND32 to ND512 (approx. 5–9 stops)
• Compatible camera models: DJI Osmo Action 3, 4, 5 Pro
• Form factor: adjustable/rotating fader filter designed for action camera housings
• Primary purpose: exposure control and motion blur management for video
• Typical use environment: bright outdoor conditions and high‑speed shooting

How to use

Mount the adjustable fader filter to the lens opening or compatible adapter of the DJI Osmo Action 3/4/5 Pro housing following your housing manufacturer’s instructions. Rotate the fader ring to set the desired attenuation between ND32 and ND512 while monitoring exposure on the camera display. Use lower ND values for moderate reduction of light and higher values for very bright conditions or pronounced motion blur effects. Check framing and focus after fitting the filter and adjust ISO and shutter speed as needed to maintain the target frame rate and desired look.

Usage recommendations

For consistent motion rendering during action sequences, select an ND value that allows a shutter speed appropriate for your chosen frame rate (for example, shutter speed close to double the frame rate for natural motion blur). Keep the filter and housing surfaces clean to avoid introducing artifacts, and verify compatibility with your specific housing model before extended water exposure.
