Quick Answer
The DJI O4 Wide Air Unit is a fourth O4 variant that pairs the lightweight 1/2-inch sensor and 13.3 g weight of the O4 Lite with a 159° ultra-wide lens, making it the widest-FOV option in the entire O4 family, wider even than the O4 Pro at 155°. It records 4K/60fps, transmits 1080p/100fps at 20 ms latency in Racing Mode, and runs the same O4 transmission module as the standard O4 Air Unit, only the camera module differs.
What DJI Actually Changed
DJI released the O4 Wide in late June 2026 with almost no fanfare. We added it to our catalog the same week because it fills a gap we had been patching with workarounds: pilots on 2-inch and 3-inch builds want the immersive perspective of a GoPro without bolting 60 g of action camera to a 50 g airframe.
The O4 Wide Air Unit takes the existing O4 transmission module, keeps the 1/2-inch CMOS sensor, and swaps the lens for a 159° ultra-wide optic. Same 30 × 30 mm module, same 3-in-1 cable, same antenna. Nothing about the RF chain or video encoding changed.
What did change is the field of view. The standard O4 Lite gives you 117.6°. The O4 Pro offers 155°. The O4 Wide pushes to 159°. For context, that is a 35% wider perspective than the standard O4 Lite, captured at the same 4K/60fps resolution and the same 13.3 g total weight.
Where It Sits in the O4 Lineup
| Spec | O4 Lite | O4 Wide | O4 Pro |
|---|---|---|---|
| FOV | 117.6° | 159° | 155° |
| Sensor | 1/2-inch | 1/2-inch | 1/1.3-inch |
| Weight (with camera) | ~13 g | 13.3 g | 32 g |
| Recording | 4K/60fps | 4K/60fps | 4K/120fps |
| Live Feed | 1080p/100fps | 1080p/100fps | 1080p/100fps |
| Racing Mode | 20 ms | 20 ms | 15 ms |
| Mounting | 25.5×25.5 mm | 25.5×25.5 mm | 20×20 mm |
| Input Voltage | 7.4–26 V | 3.7–13.2 V | 7.4–26 V |
The O4 Wide sits squarely in the micro-build tier. The 3.7 V minimum input lets it run on a 1S LiPo, which is what most 2-inch whoops use. The O4 Pro is a different animal entirely: bigger sensor, nearly triple the weight, dedicated 20×20 mm mounting, and the 15 ms Racing Mode that only works with Goggles 3 and Goggles N3.
Who the O4 Wide Is Actually For
We see three clear use cases. First, toothpick and micro-long-range pilots who want cinematic wide-angle footage without the O4 Pro's weight penalty. The 13.3 g total keeps sub-250 g builds honest. Second, cinewhoop builders flying 2-inch ducted quads indoors, where the 159° FOV captures tight spaces a narrower lens would miss. Third, racing pilots who want maximum situational awareness in Racing Mode without stepping up to the heavier O4 Pro.
For pilots who already own an O4 Lite: the Wide is a complement, not a replacement. The wider lens introduces more fisheye distortion in the live feed, which some racing pilots find disorienting at close range. If you fly gates, the O4 Lite's narrower 117.6° FOV gives a cleaner perspective. For freestyle or cinematic lines in open air, the Wide's 159° is transformative.
What We'd Actually Buy
For micro builds and whoops under 3 inches, we would pick the O4 Wide over the standard O4 Lite. The 42-degree FOV increase is worth it for the type of flying these airframes do, and the weight is identical. For 5-inch freestyle where you want the best possible image quality and can carry 32 g, the O4 Pro with its 1/1.3-inch sensor and 4K/120fps is still the right call. The standard O4 Lite remains our pick for pure racing, where the narrower FOV helps with depth perception through gates.
The one thing to watch: goggle compatibility. The O4 Wide works with Goggles 3, Goggles N3, Goggles 2, and Goggles Integra. Racing Mode at 20 ms requires Goggles 3 or Goggles N3. If you are on older Goggles V2, you are limited to standard mode and will not see the latency benefit.
FAQ
Q: Is the O4 Wide a replacement for the O4 Lite?
No. It is a parallel variant. The O4 Lite stays in the lineup for pilots who prefer the narrower 117.6° FOV, particularly for racing where fisheye distortion hurts depth perception.
Q: Can I swap just the camera module on my existing O4 Lite?
The O4 Wide ships as a complete air unit (transmission module plus camera). The camera modules use the same coaxial connector, but DJI does not sell the wide camera module separately at launch. You are buying the full unit.
Q: Does the O4 Wide support the same 23GB built-in storage?
Yes. The O4 Wide includes 23GB of internal storage for 4K/60fps recording, matching the O4 Lite and O4 Pro. It also supports RockSteady stabilisation and offline Gyroflow data logging.
Q: Will the O4 Wide work with my DJI FPV Remote Controller 3?
The DJI FPV Remote Controller 3 pairs with Goggles 3 and N3, which are both compatible with the O4 Wide. The controller talks to the goggles, not the air unit directly, so compatibility follows your goggle choice.
