Ulanzi Black Mist 1/4 Camera Lens Filter for DJI Osmo Pocket 3 / Ulanzi PK-01

The Ulanzi Black Mist 1/4 Camera Lens Filter for DJI Osmo Pocket 3 / Ulanzi PK-01 is a screw-on diffusion filter designed for small camera lenses such as those on the DJI Osmo Pocket 3. It produces a subtle softening effect that reduces contrast, tames highlights and creates a gentle glow around bright areas. The filter mounts as a 1/4 element to provide on-camera creative control for portrait video, interviews, vlogs and run-and-gun shooting without complex post-production.

Advantages

This filter delivers a controlled diffusion that preserves image detail while smoothing skin tones and preventing harsh highlights. Its screw-on design ensures secure, repeatable mounting on compatible lens housings, and the compact form factor is suitable for small action and pocket cameras. The Black Mist effect helps achieve a more cinematic look in-camera, reducing the need for heavy digital grading and enabling faster delivery of footage.

How to use

Usage recommendations

For best results, use the Black Mist 1/4 when shooting portrait or interview footage under mixed lighting to achieve smoother skin tones and a cinematic highlight roll-off. Combine with natural or soft key lighting rather than harsh direct lights to maximize the diffusion effect. Check framing for any potential vignetting on very wide angles and adjust composition or remove the filter if necessary.
