Filter set Freewell for DJI O4 Air Unit Pro FW-O4-STD ND and CPL

Freewell filter set for DJI O4 Air Unit Pro

The ND filter set from Freewell is an indispensable accessory for drone owners using the DJI O4 Air Unit Pro. In the set you will find four filters - ND8, ND16, ND32 and ND64 - which allow you to effectively reduce the amount of light entering the lens in sunny conditions. With them, you'll capture smooth, cinematic shots with faithful colors and proper exposure. The filters are made of high-quality optical glass, and are designed to be lightweight, durable and fit perfectly on the camera - without affecting the operation of the gimbal. This is the choice for discerning filmmakers who want to extract the maximum potential from their DJI O4 Air Unit Pro.

Dedicated fit and full compatibility

The filters were designed specifically with the DJI O4 Air Unit Pro in mind, which means not only a perfect fit, but also safety and stability during flight. Thanks to the precise design, the installation and removal of the filters is quick and intuitive, and the whole thing works perfectly with the design of the FPV camera, without disturbing its aerodynamics or the work of the gimbal.

Exposure control in all conditions

The kit includes four filters with different optical density values - ND8, ND16, ND32 and ND64 - allowing you to flexibly adjust the recording parameters to the light level. On sunny days, you'll reduce the risk of overexposure, achieving more natural motion blur and the smoothness you expect from professional aerial shots.

High-quality optical glass and natural colors

Freewell uses premium optical glass in its filters, which guarantees exceptional clarity and faithful color reproduction. True Color technology eliminates unwanted discoloration and maintains full sharpness of detail - without compromising quality, even in the most demanding scenes.

Maximum safety and easy operation

Each filter has been made to weigh as little as possible, which is crucial for FPV systems. The ultra-lightweight design doesn't disturb the balance of the gimbal or in-flight stability, allowing you to focus solely on the shot. Protective coatings on the surface of the filters protect them from dust, scratches and fingerprints. Their rugged construction makes them perfect for the field, and they are as comfortable as possible to use for both insertion and storage. They are a reliable choice for intensive outdoor FPV filming.

How to use

Select the ND filter that matches current lighting (lower ND number for lower light, higher ND number for bright conditions) and mount it onto the DJI O4 Air Unit Pro camera following the product's quick-attach alignment. Verify gimbal balance and perform a short hover test after installation to confirm stable operation. Remove fingerprints or dust with the included cleaning cloth before use.

Recommendations

For best results, start with ND8 in moderately bright conditions and move to ND16/ND32/ND64 as sunlight increases; always check exposure and shutter speed settings on your recorder to maintain natural motion blur and avoid under- or overexposure.
