K&F CPL Polarizing Filter for DJI Mini 4 Pro drone — Nano-X series (model SB8569)

The K&F CPL Polarizing Filter for DJI Mini 4 Pro drone — Nano-X series (model SB8569) is a circular polarizer designed specifically to fit the optical system of the DJI Mini 4 Pro. It reduces reflections and surface glare from water, glass and other non-metallic surfaces, increases color saturation and contrast, and helps produce clearer skies and richer outdoor aerial images. The filter is part of the Nano-X line, engineered for lightweight use on small drones without compromising image sharpness.

Advantages

This CPL filter selectively blocks polarized light to reduce unwanted reflections and haze, improving image clarity and color fidelity in bright conditions. Its circular design ensures compatibility with the autofocus and exposure metering systems of the drone camera. The Nano-X build emphasises low weight and balanced optical performance, helping to maintain stable flight characteristics while attached to the Mini 4 Pro. The multi-coated glass minimizes flare and ghosting for consistent results across different lighting situations.

Suitable for

• Aerial landscape photography with enhanced sky contrast and color saturation
• Filming over water, snow or wet surfaces to reduce surface reflections
• Urban aerial shots where glass and reflective surfaces cause glare
• Outdoor videography in bright sunlight to improve overall image quality

Key specifications

• Type: Circular polarizing (CPL) filter
• Compatibility: Designed for DJI Mini 4 Pro drone camera optics
• Construction: Multi-coated optical glass for reduced flare and ghosting
• Frame: Lightweight profile to suit small drone gimbal balance
• Function: Reduces reflections, increases color saturation and contrast

How to use

Mount the CPL filter onto the DJI Mini 4 Pro camera following the manufacturer's alignment and attachment method for the Nano-X series. Rotate the filter ring while observing the live view to adjust the degree of polarization until reflections are reduced and desired sky or color contrast is achieved. Re-check gimbal calibration and flight balance after attaching the filter, and verify autofocus and exposure metering in camera preview before recording or shooting stills.

Usage recommendations

Use the CPL filter mainly in bright outdoor conditions and when photographing reflective surfaces; reduce or remove it for low-light, high-contrast shadow detail work, or when using certain ND/UV filter stacks that may affect exposure or gimbal balance. Regularly clean the optical surfaces with a soft microfiber cloth and store the filter in a protective case when not in use.
