After many aftermarket options popped up, DJI finally decided to make their won wide angle version of the O4 air unit, often called the O4 lite. This new entry makes the entry point of this kit way lower, while keeping warranty on the product. At first glance, the old and new units are pretty much identical, and for the most part they are. Let's look into what makes them great for different applications.
Main Specifications

What's the Big Deal?
For those coming from other video systems, the standard for field of view is 150+ degrees of field of view. This new version now accommodates people that are used to wider angle systems. Having a wider angle lens makes flying maneuvers easier and makes seeing your surroundings in flight .
Image Quality
Both air units use a 1/2-inch CMOS sensor capable of recording 4K video at up to 60fps, so overall image quality remains very similar. You still get excellent detail, low latency digital FPV, and onboard recording without needing a separate HD camera for many builds.
If you're hoping for better low-light performance or higher frame rates, those upgrades belong to the O4 Air Unit Pro—not the Wide version
Size and Weight
One reason the original O4 Air Unit became so popular is its incredibly small footprint. At approximately 8.2 grams, it's ideal for lightweight 2-inch and 3-inch builds where every gram matters.
The O4 Wide Air Unit does gain some weight, weighing in at 13.3g. While that makes it too heavy for 1s powered quads, makes it a way better offering for all other micro and sub 250g drones.
Flight Experience
Here's where pilot preference really matters.
Choose the standard DJI O4 Air Unit if you:
- Fly racing drones
- Prefer a more natural perspective
- Want maximum precision
- Mostly fly smaller quads
Choose the DJI O4 Wide Air Unit if you:
- Love freestyle flying
- Enjoy cinematic cruising
- Fly close to obstacles
- Want footage that feels faster and more immersive
Many freestyle pilots appreciate the wider view because it helps keep obstacles in frame during aggressive maneuvers and creates a greater sense of speed.
Shared Features
Aside from the lens, both systems share most of the same technology:
- 4K onboard recording
- DJI O4 digital video transmission
- Low-latency HD FPV feed
- Compatibility with DJI Goggles 3, Goggles N3, Goggles 2, and Goggles Integra
- Betaflight compatibility
- Lightweight design for compact FPV builds
DJI vs Flywoo
Now how does this compare to the Flywoo offering. The Flywoo version weights in at 10.9g, which is quite a bit lighter than the DJI unit. They offer a series of filters to fit your filming needs. It comes down to your needs, the DJI version is now more readily available and comes with a manufacturer warranty. The Flywoo is lighter and tends to be a little cheaper.
Final Thoughts
DJI didn't reinvent the O4 platform with the Wide Air Unit—they refined it. By keeping the same compact design and dependable O4 transmission while dramatically expanding the field of view, DJI has created an attractive option for freestyle pilots who wanted a wider perspective without the added size or cost of the Pro model.
Ultimately, your decision comes down to one question:
Do you prefer precision or immersion?
If precision is your priority, stick with the standard O4 Air Unit. If you want to capture more of every flight and make your footage feel faster and more cinematic, the O4 Wide Air Unit is the clear winner.
