Description
The DolphinRC DJI O4 Wide Air Unit Lens Mod Kit is a 6061 aluminum camera-housing modification accessory for the camera identified in the supplied specifications as the DJI O4 Wide Air Unit Camera. It provides multiple mounting positions and an included thermal pad in a compact 12 × 20 × 21 mm format. Choose the mod kit alone or a bundle with a separate VTX heatsink. This is a mechanical accessory, not a replacement optical lens or a complete DJI Air Unit.
Key Features
- 6061 aluminum construction: a rigid housing structure for a custom FPV camera installation.
- Multiple mounting positions: the supplied diagram labels 6 mm and 16 mm hole spacings for build planning.
- Thermal pad included: provides a thermal interface at the intended contact surface. It is a pad, not a tube of thermal grease.
- Low accessory weight: specified as 3.68 ± 0.1 g without the separate heatsink; this is not the weight of a complete camera or VTX bundle.
- Optional VTX cooling accessories: select the standard heatsink case or a lightweight black or light-blue heatsink bundle.
When a camera mount needs frequent adjustment, a dedicated metal housing gives the build a defined mounting structure. Correct screw engagement and careful tightening still matter: aluminum threads can be damaged by overtightening, and no housing is immune to wear or crashes.

The 12 × 20 × 21 mm dimensions and 3.68 ± 0.1 g weight below describe the mod accessory, not the separate VTX heatsink. Bundle dimensions, combined weights and additional heatsink hardware quantities are not specified in the supplied materials.
Camera, optical lens assembly and DJI Air Unit electronics are not included. A camera shown installed is an illustration of use, not a kit inclusion.
Compatibility & Specifications
Dimensions and weight are supplier estimates and may vary slightly. The scale photo shows one sample at approximately 3.73 g, which falls within the listed tolerance.
Check your exact camera model, housing geometry, frame side plates and cable clearance before ordering. The supplied compatibility wording does not establish universal fit across DJI O4 variants, O4 Pro, O3 or other cameras. Matching one hole spacing alone does not guarantee a complete fit.



Package Includes
The base lens modification kit contains:
- O4 Wide lens modification kit × 1
- Thermal pad × 1
- M2 × 4 mm camera-fastening screws × 4
The three heatsink bundle options additionally include the corresponding VTX heatsink shown in their option images. The base package image does not specify a separate heatsink hardware list.

Installation Precautions
No product-specific assembly manual or torque specification is included in the supplied page. The following are preparation checks, not a substitute for the correct camera disassembly and installation instructions.
- Disconnect power before handling the camera or VTX. Check the exact camera model and confirm the modification procedure before removing its original housing.
- Protect the lens, sensor area and camera cable from tools, dust and strain. Do not force connectors or pull on the cable.
- Dry-fit the mod housing and check the intended thermal-pad contact surface, cable route, mounting-hole alignment and frame clearance.
- Use the supplied camera-fastening hardware only where appropriate for the actual assembly. Tighten carefully without forcing or stripping threads; no tightening torque is specified here.
- If your option includes a VTX heatsink, confirm its separate fitment and instructions. Keep electrical components insulated as required, maintain airflow and check image output and camera security before flight.
This accessory does not change the optical field of view by itself and is not a guaranteed cure for overheating. If the correct modification procedure is unclear, seek installation guidance before disassembly rather than experimenting on the camera.
Product FAQ
Is a camera or DJI Air Unit included?
No. This listing is for the modification accessory, with an optional VTX heatsink bundle.
Does “Wide” mean it includes a wide-angle replacement lens?
No optical replacement lens is listed. “O4 Wide” is the compatibility wording used in the supplied product materials.
Is the included thermal material grease or a pad?
The package image identifies one thermal pad. It should not be described as a supplied tube of grease.
Does every version weigh 3.68 g?
No. The stated 3.68 ± 0.1 g is for the mod accessory without the separate heatsink. Combined bundle weights are not provided.
Will it fit every DJI O4 camera or frame?
Universal compatibility is not established. Check your exact camera and frame dimensions against the specification and mounting diagram before purchasing.
Choose the mod-only or heatsink-bundle option that matches your build. Contact SoarSky with your exact camera model and frame details if you need a fitment check before ordering.
