Happymodel FOV Extender Kit for DJI O4 Camera

Overview:
The Happymodel FOV extender kit is a lightweight optical upgrade designed to widen the field of view on a DJI O4 Air Unit Camera (not Pro version) fitted to a micro whoop drone such as the Mobula7 O4 and Mobula8 O4. This is the same kit supplied fitted to the Happymodel Mobula8 O4 2S HD Micro Whoop (ELRS).

In typical O4 installations, the stock lens offers a good balance of image quality and central detail, but pilots seeking a more immersive perspective will appreciate the extended viewing angle that this kit delivers without compromising overall setup weight or requiring a separate camera module. The kit also includes a modest set of optical filters to help manage bright conditions and improve dynamic range when filming.

This accessory is particularly useful for pilots who want broader situational awareness and greater cinematic context in their FPV footage while keeping the DJI O4 video system’s clarity and reliability.

The extender’s design integrates directly into the existing adjustable canopy on Mobula7 O4 and Mobula8 O4 frames, maintaining a clean installation and ensuring the wider perspective aligns correctly with the aircraft’s forward axis.
