The DJI O4 Lite camera is an incredible piece of hardware. Weighing just 8g but capable of 4K 60fps videos, perfectly for micro FPV drones. While image quality is genuinely impressive, one major complaint has been the narrow field of view. At just 117°, the stock O4 lens feels zoomed in. It’s flyable, but it’s not enjoyable. And once you apply stabilization in Gyroflow, the image becomes even more cropped, which makes the footage feel less immersive. That’s exactly where the Flywoo O4 Wide Angle Lens comes in. After testing the new version, I honestly feel this is how the DJI O4 camera should have been released in the first place.

Where to Buy
Get the Flywoo Wide Angle Lens from:
There are two versions, you can get the modified camera that comes with the wide angle lens installed (camera set), or you can just get the DIY kit and modify your own O4 camera (lens set). Personally I prefer the modified camera set because modifying your own O4 is quite time consuming and risky.
Why a Wide-Angle Lens Is So Important on the DJI O4
For FPV flying, FOV (field of view) isn’t just about aesthetics—it directly affects how confident and comfortable you feel in the air.
With the stock O4 lens:
- The image feels zoomed and restrictive
- Close-proximity flying is harder
- Stabilized footage looks even more cropped
A wider FOV gives you:
- Better spatial awareness
- A more natural FPV “speed feel”
- Stabilized footage that’s easier to watch
Flywoo’s wide-angle lens expands the FOV of O4 camera from 117° to 155°, which is a massive improvement.
A Quick Look Back: The Old Clip-On Adapter
Flywoo previously released a clip-on wide-angle adapter, which I reviewed earlier. While it did improve the FOV significantly, it came with a few drawbacks:
- Reflections and lens flare from stacking optics
- Vignetting in the corners caused by the adapter
- Slight softness and loss of clarity near the edges
It was a step in the right direction, but clearly a compromise.
The new version is a complete redesign, and it fixes almost all of those issues.
What’s New With the Flywoo O4 Wide Angle Lens
This new lens is not just an add-on—it’s a proper lens replacement designed specifically for the DJI O4 Lite camera (not the O4 Pro).
Key improvements include:
- More professional looking design and build quality
- Less vignetting
- Sharper image
- Less glare and internal reflections
- Proper Gyroflow support via custom lens profiles
Most importantly, the image finally feels wide, immersive, and natural, especially for FPV flying.
Weights are nearly identical so the main advantage is just image improvement and build quality.

Image Quality
I tested the new wide angle lens on the Firefly18 1S, check out some footage here:
Compared to the stock O4 lens, the increase in FOV is significant when using the new Flywoo Wide Angle Lens. However it’s clear that it’s not as wide as the previous clip-on lens, so I think the actual FOV is slightly less than 155°. But the improvement is still massive.

There is no more adapter edges appearing in the image and no corner blur. Clarity and sharpness are also as good as the original O4 lens, if not better. Everything looks very clean and sharp. Lens glare and reflection are also massively reduced.
Stabilization and Gyroflow Support
To use stabilization properly, it’s highly recommended to use Flywoo’s custom lens profiles in Gyroflow. These are available for both 16:9 and 4:3 aspect ratios. It also works without custom lens profile but the image might look warped during yaw movements.
Buying Options: DIY vs Pre-Modified Camera
Flywoo offers this lens in multiple configurations, which is important depending on your skill level.
1. Pre-Modified Camera (Recommended)
This version comes with an O4 camera that has the wide-angle lens installed out of the box
This is by far the easiest and safest option, and it’s the one I recommend for most pilots. Modifying the O4 camera is not very beginner-friendly.
However, with any non-official O4 camera, you will always get a red warning in the corner when flying (“camera calibration error”). It’s nothing to worry about, the camera is fully functional as I’ve tested.
2.DIY Lens Kit
You can modify your own O4 camera using the DIY kit:
- Remove the image sensor board from the original housing
- Glue the image sensor to the new housing,
- Adjust focus manually
The process is a bit harder and you could damage the camera if not being careful. Detailed instructions can be found here.
Mounting Options and Compatibility
The wide angle lens housing is 14mm wide, identical to the original O4 Lite camera. The distance between the two mounting holes is also the same, however, they use different screws:
- The original O4 Lite uses M2 self-tapping screws
- Flywoo uses M1.4 screws

Adapters are also included to support other mounting:
- 18mm adapter (supports Flywoo’s BNF drones. With washers, it should also work in 19mm micro analog camera mounts)
- 20mm adapter (supports DJI O4 Pro and O3 mounts)
One issue though, Flywoo needs to pay more attention in quality control: my O4 Pro adapter came defective (one side is glued the wrong way).
Installation
To replace the original O4 camera, you need to remove the glue on the connector first.
Connect the MIPI cable to the wide angle camera using the included adapter
That’s it.
To use either the 18mm or 20mm adapters, secure the 4 screws on the sides.
One important note: if you’re upgrading a Flywoo Firefly16 or Firefly18 1S, you’ll likely need the updated canopy designed for the new lens.
ND Filter
Flywoo also provides a brand new clip-on ND filter that attaches cleanly to the front of the lens, which is a nice bonus for cinematic flying. Get it here: https://oscarliang.com/product-kix0
UV, ND8, ND16 and ND32 are available. Note that these filters only support this wide angle lens and don’t work on any other cameras at the moment.

Camera Calibration Error (Should You Worry?)
As mentioned, any aftermarket O4 camera will give you this warning “Camera calibration error” in your goggles (it’s there all the time). But in my testing, the camera worked absolutely fine and I didn’t notice anything wrong apart from the annoying warning, so I wouldn’t worry about it.
Final Verdict: Is the Flywoo O4 Wide Angle Lens Worth It?
Absolutely yes.
This new Flywoo wide-angle lens is a massive improvement over the stock DJI O4 lens. Not only it offers a much more usable field of view without compromising clarity, it also provides more mounting options thanks to the adapters. It doesn’t magically turn the O4 Lite into an O4 Pro—but it gets it much closer. I genuinely feel this is how the O4 camera should have come from DJI in the first place.
If you fly DJI O4 Lite and care about immersive FPV footage, this upgrade is very easy to recommend.
