Has anyone experience having dark circular area on their screen whilst taking photos or videoing. I had to send my mavic 3 back as suggested by the support team. They've look at it and confirm that there's no problem with the images. I then had to send them a video footage to show exactly what I mean ,they've investigated again and confirm that alls okay and are at present sending the drone back to me.

I meant to state Mavic 3

I'm not understanding.  Are you saying that you have found issues with the photos, and DJI denies that there are problems with the drone taking the photos?  If so, can you share an example photo?

It’s to the right of every photo taken and video. At first I thought it was a smear on the lens,replaced it with an nd filter and it was still there’s ,even carefully wiped the lens with negative results. Waiting for the drone to be returned and I’ll have to see if it’s still there,I have been using the Rc pro as the controler.

There has been another user on this forum with similar issue. Looks like something is sitting within the Lens system that you can't get to. Whatever it is that is not acceptable and you need it fixed/replaced. Goodluck and let us know how you go. Really hope this is occurring within a sealed component and a one off and not something that can "develop" on any mavic 3?

I'm baffled how any analyst can conclude that there is no product defect.  There was a similar issue reported, and if I recall right that customer did receive a replacement.

Well I’ll have to wait and see when the drone returns to me. The DJI engineers report states that they’ve checked the camera and can’t find any fault within the system.

... that is almost unbelievable for me, really!

looks very much how dust on a sensor would look. Have you tried puffing a little air on the lens? I don't mean on the filter portion, but if you remove the glass filter, then puff some air onto the lens. Sounds like you may have already tried this. Its likely a small dust spec sitting directly on the sensor. If you look down into the lens under magnification, you should be able to maybe see the spot if it is in the glass somewhere. I would occasionally have this happen years ago in my SLR cameras. You would have to take the lens off, lock the mirror up to fully expose the sensor inside the body of the camera, then very carefully clean the sensor.

I am shocked DJI would say nothing is wrong here, unless there is just some miscommunication. For example, maybe they are saying the drone and camera do not have any defect, and they may be right in that, but hopefully they did clean the sensor to get the dark spot off. Its also possible that dot could move over time, or if the camera is jarred around. Keep us updated on how it goes.

Yes, maybe they mean "we have addressed the issue and now find no defect".  It sounds like they ran an electronic diagnostic of some kind and the electronic report came back nominal (which would not account for dust obstructing the sensor).  That's my fear.

The sensor is inside the camera, not on the lens.
If it's on the sensor, it won't be moved by blowing the lens.

Well they did provide two pictures showing no dark areas as proof that there’s no fault within the camera images. Well I hope those dark areas don’t reappear and as soon as it arrives I shall be taking out their care refresh 1 year as a precaution, should any other problem reoccurs.

Do you know what aperture was used in these shots? One way they may have produced shots without the mark showing using a very big aperture opening e.g f/2.8 which could reduce the effect, conversely it would be more obvious with a smaller  aperture e.g f/11 either that or do live near Roswell???

These are the two pictures they sent to prove that the dark spot has now gone.

It looks as if these were taken indoors.

Hi, I have now questioned DJI,if these photos were taken indoors, and if the problem of the dark area is still there ,then I’ll be requesting a full refund and continue using my ever faithfull mavic 2 pro.

Text I’ve received.

When you get the drone back I would run through some test shots across all apertures and see what results you get. Good luck!

Absolutely, will be doing that,thanks.

Thinking about your case I would also run different tests a different focus points though I would have thought it would have been worse if DJI had taken those shots focusing on something close up as opposed to close to infinity like your initial shots. i.e. if it's something in-between the sensor and front lens the further away you are focused the less visible it would be.  Is going to be a real puzzle if your tests come up clean, I guess you then have something moving around in there which could be really frustrating to recreate!

Well I must say that DJI has shipped out my drone yesterday noon and I’m expecting it back sometime this afternoon,batteries are going to be charged and I’ll be busy flying it carrying out various tests. Got an email from DJI recommending me taking out their DJI care refresh 1 year. What’s everyone’s opinion in this , is it a good step.

Well I must say,I’m impressed that the drone left the Netherlands yesterday afternoon and I’ve received it back today at 13.40. Flew the drone for a length of time changing all the settings on the camera ie,shutter,aperture etc, and the dark area is gone, I’ll be running more tests tomorrow . Still contemplating in taking out the DJI care refresh 1 year.

Well I used two batteries at length,so dar no issues with dark spots,still aiming to carry out more tests when the weather improves. Need to take a good look at all footages,just to reassure myself that if it was dust within the lens that it hasn’t moved around or causing blurr areas,which is possible. Took the plunge and took out the care refresh plan 1 year.

What's the longest shutter speed on the M3? are you able to set it on that take some pictures and shine a light down into the lens to see if anything might be down in there? So far looking good though. Good you have this post now as if it is something and dislodges in the future you can refer back to this for support with your case to DJI.
