Review: Caddx Nebula Pro Camera for DJI FPV System

Caddx released the Nebula Pro camera which is an alternative camera for the DJI FPV system. This is a remake of the previous Nebula Nano/Micro camera which wasn’t very good. Is the Nebula Pro better? Let’s find out.

The previous Nebula from Caddx was very cheap and 3 grams lighter than the stock DJI camera, but image quality was just disappointing, to say the least. So they made a new version, the Nebula Pro which has much improved image.

Still debating whether to get into DJI FPV system? Check out my review.

Already bought the DJI system? Here’s a list of DJI FPV System upgrades and accessories you don’t want to miss out on.

Where to Buy?

You can get the Nebula Pro camera alone (see here how to connect camera to Air Unit), or with the Vista Air Unit as a combo. These are affiliate links.

Specs and Features

Let’s compare the specs and features of the new camera with the older ones.

** my own measurement

Here’s the official specification of the Nebula Pro:

  • Image sensor: 1/3-inch CMOS sensor
  • Resolution: 720p 60fps
  • Aspect Ratio: 4:3 & 16:9 (Switchable)
  • FPV / Recording FOV: 150°
  • Lens: 2.1mm f/2.1
  • FPV Latency: <28ms
  • Weight: 6g
  • Dimension: 19*19*20mm
  • Shutter: Rolling Shutter
  • Housing: Aluminum alloy

Nebula Pro vs. Nebula Nano

The new Nebula Pro can do both 4:3 and 16:9 aspect ratios, supports low latency mode as well as high quality mode. That’s something that the older Nebula couldn’t do: it was stuck at 16:9 high quality mode, not to mention you couldn’t even adjust any camera settings which was inconvenient.

It is heavier than the Nebula Nano, but it shows huge improvements in image quality from the previous version. Spoiler alert: it’s now very close to the original DJI camera.

It no longer has analog output – it can only be used with DJI FPV system, either the Vista or the Full size Air Unit.

Nebula Pro vs. DJI Camera

The Nebula Pro has almost the same features as the DJI camera, with a few small differences.

It is lighter and smaller than the DJI camera with its standard 19x19mm micro camera size which fits perfectly in most FPV drone frames. The unusual 22x21mm size of the DJI camera requires 3D printed camera mount or a frame that is designed specifically for this camera size.

Caddx did say the Nebula Pro is using a different image sensor than the DJI camera, but it uses what it seems to be the exact same lens, so you could use the same 3D printed lens protectors on the Nebula Pro.

Nebula Pro Image Quality

From inside the goggles, honestly I couldn’t tell any difference when flying the two cameras back to back.

But when comparing the DVR footage side by side, there is some noticeable differences in image color. The Nebula Pro has slightly colder tone than the stock DJI cam. But apart from that they look pretty much identical, including field of view, wide dynamic range, etc.

Conclusion

Is the Nebula Pro a success?

In my opinion, yes. It has similar image quality to the original DJI camera and yet it’s a couple of grams lighter, has 19x19mm form factor and costs a few dollars less, what’s not to like?

If you ever break the stock DJI camera, I think the Caddx Nebula Pro can be a good replacement too, but do watch out for the different camera dimensions if your frame support it.
