After a myriad of problems with my Cine, here's another kick in the gonads...

I finally got out in the bright sun to shoot a building for a client and found that the Hasselblad's sensor has dust on it.  This dirty sensor snuck past me on my other test flights because I was shooting in low light on a wide aperture.  Only when I closed it up a little (f5.6) on this bright day the dust became even more noticeable. Video screenshot attached.

The lens filter cover & lens itself are crystal clear & clean.

Does anyone else have this problem?

Cine Dirty Sensor

I have been flying drones for about 2 years and watched countless Youtube videos but never have I seen Sensor Dust. That's a real worry if it is. On an interchangeable lens camera it's pretty easy to fix but on a sealed drone gimbal? I think you are looking at a return to where you purchased it, you shouldn't have to put up with that. Good luck!  

Oh dear this post doesn't offer much hope either...

Definitely back to the shop!

It happens very occasionally (at least, we see it on this foruM), but you can't do anything about it.
Start a support case.

It does not look like a sensor dust, I'm sorry. Maybe a part of the internal optical tract (lens assembly), but not a sensor. Not that it helps in any way, since we can't clean it up either.
I would still have a second look on the filter (back side) or lens front element. And don't just look, give it an actual clean with the appropriate method. For a spot that small the particle might be nearly imperceptible for a naked eye. Good luck!

Can’t believe I’m the only one that received a dirty sensor. My luck…

I have seen it before obviously would have to have been there through production. Unless its something else. Can you take picture of the Lens with cover off and maybe blow it up “zoom in “ and post here.

What I have seen before is not a single dust spot but a collection of dust spots. Return it or just keep removing in post.

I use Canon pro DSLRs for photography and that definitely looks like sensor dust but I'm not familiar with the construction of the sealed sensor assembly. So it could be an internal filter rather than the sensor, but the end result to you is the same.

You should stop it down to f/11 and then get full blue sky shots to see if there is more dust. Works best when not focused.

Been busy, sorry it took so long. Here's a macro shot with the cover removed:

Wish I would've seen your reply before I took these images, I've would've un-focused them. At F11 focused I don't see anymore dust at least.

Well it looks fairly clean, but from the photos it clearly exists. I think if it was me I would return it. You have no access to properly clean it so return it .

What you did? I also have dust on my M3 sensor.

I contacted DJI support and they had me ship it back. They replaced my Mavic 3 Cine with a new one.

Yep, you basically need to change the camera, it happened on my previous Air2S.

Yeah the same with my Mavic 3, they shipped new one with new serial number.
