The DJI O4 Lite digicam is an unimaginable piece of {hardware}. Weighing simply 8g however able to 4K 60fps movies, completely for micro FPV drones. Whereas picture high quality is genuinely spectacular, one main grievance has been the slim subject of view. At simply 117°, the inventory O4 lens feels zoomed in. It’s flyable, nevertheless it’s not fulfilling. And when you apply stabilization in Gyroflow, the picture turns into much more cropped, which makes the footage really feel much less immersive. That’s precisely the place the Flywoo O4 Huge Angle Lens is available in. After testing the brand new model, I truthfully really feel that is how the DJI O4 digicam ought to have been launched within the first place.

The place to Purchase
Get the Flywoo Huge Angle Lens from:
There are two variations, you may get the modified digicam that comes with the extensive angle lens put in (digicam set), or you possibly can simply get the DIY package and modify your individual O4 digicam (lens set). Personally I desire the modified digicam set as a result of modifying your individual O4 is kind of time consuming and dangerous.
Why a Huge-Angle Lens Is So Essential on the DJI O4
For FPV flying, FOV (subject of view) isn’t nearly aesthetics—it straight impacts how assured and cozy you’re feeling within the air.
With the inventory O4 lens:
- The picture feels zoomed and restrictive
- Shut-proximity flying is more durable
- Stabilized footage appears much more cropped
A wider FOV provides you:
- Higher spatial consciousness
- A extra pure FPV “velocity really feel”
- Stabilized footage that’s simpler to observe
Flywoo’s wide-angle lens expands the FOV of O4 digicam from 117° to 155°, which is an enormous enchancment.
A Fast Look Again: The Previous Clip-On Adapter
Flywoo beforehand launched a clip-on wide-angle adapter, which I reviewed earlier. Whereas it did enhance the FOV considerably, it got here with a number of drawbacks:
- Reflections and lens flare from stacking optics
- Vignetting within the corners brought on by the adapter
- Slight softness and lack of readability close to the perimeters
It was a step in the suitable path, however clearly a compromise.
The brand new model is a whole redesign, and it fixes virtually all of these points.

This new lens isn’t just an add-on—it’s a correct lens substitute designed particularly for the DJI O4 Lite digicam (not the O4 Professional).

In comparison with the inventory O4 lens, the rise in FOV is critical when utilizing the brand new Flywoo Huge Angle Lens. Nevertheless it’s clear that it’s not as extensive because the earlier clip-on lens, so I believe the precise FOV is barely lower than 155°. However the enchancment remains to be large.

There is no such thing as a extra adapter edges showing within the picture and no nook blur. Readability and sharpness are additionally nearly as good as the unique O4 lens, if not higher. The whole lot appears very clear and sharp. Lens glare and reflection are additionally massively lowered.

Nevertheless, with any non-official O4 digicam, you’ll at all times get a crimson warning within the nook when flying (“digicam calibration error”). It’s nothing to fret about, the digicam is totally useful as I’ve examined.

- Regulate focus manually
The method is a bit more durable and you may injury the digicam if not being cautious. Detailed directions may be discovered right here.

One subject although, Flywoo must pay extra consideration in QC: the O4 Professional adapter got here faulty – one facet is glued the mistaken approach.
Putting in
To switch the unique O4 digicam, you must take away the glue on the connector first.

Digicam Calibration Error (Ought to You Fear?)
