DJI O4 Pro Air Unit ND Filters and Lens Protectors

Pro-level Neutral Density (ND) filters and clear lens protectors made specifically for the DJI O4 Pro Air Unit. Does not fit O4 Lite.

Made for Action

Camera Butter O4 Pro filters are the only ones made with Corning Gorilla Glass, making both the ND filters and clear lens protectors considerably stronger than filters made from conventional optical glass. Our O4 ND filters acre actually stronger than most lens protectors!

Made to fit into small frames

Our O4 Pro filters and lens protectors are just 20.6 mm wide - only 0.6 mm wider than the O4 Pro camera. That means they need very little clearance around the camera and will fit into almost every O4 Pro frame available.

The top extends about 2 mm above the camera's lens hood. If you don't have clearance above the camera, the filter can be installed upside down.

Optical quality you can measure

Our O4 Pro ND filters use high-quality optical coatings for exceptionally neutral transmission with very little visible colour shift. High-quality nanocoatings also shed water and resist fingerprints, oils and dirt.

Made specifically for the DJI O4 Pro Air Unit

Unlike filters primarily designed for the Avata 2, Camera Butter O4 Pro filters and lens protectors are designed specifically for the O4 Pro and FPV use. That means:

• They fit tighter and stay on more securely
• They fit into very narrow O4 Pro installations
• Corning Gorilla Glass makes them much tougher than filters made from conventional glass

Get the most out of your DJI O4 Pro while giving the exposed camera lens serious protection.

Pack options

The full pack contains:

• ND4
• ND8
• ND16
• ND32
• Magnetic carrying case

Also available as a 2-pack of clear lens protectors, an ND8/ND16 2-pack, and a 2-pack of ND32 filters.

Installation and removal - IMPORTANT!

To install: Push the filter firmly down first, then lever it inward into place. Never press on the glass. Apply pressure only to the frame.

To remove: Use the same motion in reverse. Push the filter firmly down, then lever it outward. Do not pull it straight off. Pulling straight out can break the filter and may damage the camera's lens hood.

Note: Due to the design of the DJI O4 Pro camera, some vignetting (dark corners) may appear in Ultra Wide mode with any filter, especially when stabilization is used.

DJI O4 Pro filter FAQ

Do these filters fit the DJI O4 Lite?
No. They are made specifically for the DJI O4 Pro Air Unit and do not fit the O4 Lite.

How wide are Camera Butter O4 Pro filters?
They are 20.6 mm wide, only 0.6 mm wider than the O4 Pro camera, so they require very little clearance around the camera and fit into very tight FPV frames.

Are the ND filters also protective?
Yes. Both the ND filters and clear lens protectors use Corning Gorilla Glass, giving the camera substantially more impact protection than filters made from conventional optical glass.

Are these filters made specifically for the DJI O4 Pro?
Yes. They are designed specifically around the O4 Pro camera rather than adapted from an Avata 2 filter, giving them a narrower profile and a tighter, more secure fit.

How do I remove an O4 Pro filter safely?
Push the filter firmly down first, then lever it outward. Do not pull it straight off, as this can break the filter or damage the camera's lens hood.

Can O4 Pro filters cause vignetting?
Some vignetting can appear in Ultra Wide mode with any filter because of the camera's design, particularly when stabilization is used.
