Hello,


I  have had the DJI Mini pro for a few weeks now and already from first  footage I noticed that the right side of the images and videos or a  little softer than the others.

I  have been chatting with DJI and they told me to refresh the firmware  using the DJI Assistant 2, both on controller and drone, and  re-calibrate the drone, which I have done and the problem is there. It  actually sometimes is much worse and obvious than other times. It  probably indicates a de-centered lens issue as some people have  suggested in other posts.

So  I opened a case and have had mail conversations with support for almost  a week, and now I'm being told that the blurriness is in normal  range!!?

So it seems like DJI won't be helping me more with this issue and I'm stuck with a 1200EUR drone with lens issues
I  am not a professional photographer but have been taking photos for  almost 20 years from point and shoot cameras to DSLR and handi-cams and  mobile phones, and I see the problem there. Please take a look and these  two samples:

Please  take a look at the tree lines on the right side especially the little  yellow trees, they are completely blown out of focus. Is this normal  range?







Or this photo which I deliberately put a bit out of focus which shows the right hand side buildings are more out of focus than the center and left:



I really appreciate you opinions with the above samples as there could be some issues with my eyes and would be grateful to see what you think about the focus issues of my  drone.

If DJI deems this to be normal then I guess I'm left with no other choice then? Here in Sweden you can't return and claim a refund once you open the package. Should I write off  my invested money completely then?

To my eyes, the right side of the image is (too much) out of focus indeed.
Maybe you can share some original jpeg photo's here (not scaled down to use the forum upload or screen captures from the video) via onedrive etc.
  

Tip for you, when evalutating optics do not process the image or use any sort of blurring or filter. Can you show me (link to download if you can) the full size JPG and I can look at this for you. I have dealt with decentring and tilted lenses many times.
Provisionally, looks like it needs a new camera, which is easy for support to do when we can show the problem clearer. Let me see the jpg and ideally, RAW if you want to PM me I will be able to evaluate it for you. Ideally, more than one shot, and a different scene. Then we can make a case for you to email them, clearly showing the issue.

Thanks a lot for your responses. I do appreciate it a lot.

Here is the link to a drive folder with some original jpg photos:

I am at work just now but I will check this tonight and get back to you mate.

sorry for the duplicate post, I thought the Save button on the forum didn't work and I somehow posted same link twice.

Hi there, we are sorry for the unpleasant experience. We will forward this issue to the corresponding team for a check. Could you please provide us with the original footage for further confirmation? You can upload them to Dropbox or Google Drive and then send us the link here.

Thanks for your response Mindy. Please find the original material for download, including the video I sent to support last week in this drive link. I appreciate your help. https://drive.google.com/drive/folders/1EVFSrHOR29qQXeM8L0VxacBFX9BCXbG-?usp=share_link

At least 2 of those images look ok to me from what i can tell, are you tapping the screen or using the button to focus prior to the shots?

Had a look at these jpgs you linked to in your drive link. One shot is just a focus miss. As Bashy says, how are you focusing? Some use the screen, but I prefer the button and don't get issue. Technically a half press focuses, but if you just press it fully, it should focus and then take the shot in a one-er.

I checked the left and right sides of your frames. You will get resolution fall off in any lens to the borders, and especially corners, espeicially when this is a plastic element to reduce weight. If you look at file DJI_0137 this is the sharpest across frame shot you have provided here, but I would say my lens seems a bit sharper than this. I'd say, your lens has some extra hard fall off on the right frame, which with this sort of lens means it is not perfectly aligned to the sensor behind it. As a tip anyway, I'd urge you to go into your settings on the app and drop the NR to -2 and leave sharpening at 0. Then during RAW processing, adjust that to taste.

This aside, I think I would push to have that camera changed based on what I am seeing. I am not a video expert by any stretch but, I would again say there is much stronger resolution loss on the right border than left in this as well. No smoke without fire, as they say. There is definately copy variation out there.

I can send you a full size from mine to compare if you like?

Thanks for your respose @Bashy.  I have tried both half press of the button and tapping the screen, and even manual focusing, and I don't see much difference. I usually get acceptable stills, but in the video the problem shows the most.

@ primeshooter. You are right, the one that is out of focus (DJI_0125.JPG) is the one I purposefully put out of focus a little bit, and there it is clearly visible that the right side of frame is out of focus. However my main problem is in videos. As you can see in the footage DJI_0091_1.mp4 at around 1:25 the trees on the right side are totally out of focus and come to focus as they are framed more to the center. My phone has much sharper results across the entire frame.

I do appreciate if you can send me a full size photo of your drone so I can have a look at it.

If you pm me your email I can do this for you mate. I think it needs camera switch out, which DJI should be able to do for you.

I have had ongoing conversation with DJI following the original case I opened. They asked me to send some more footage. Today after several days of not using the drone and taking good care of it I wanted to fly it, and guess what?  The drone could not fly I got an error message about motor being stuck. One bad luck after another... I could see that the rear left motor was't rotating. Now I have to send this drone for reparation.... complete disappointment so far.  Don't know if they have any QC on these units or I am an unlucky person who got a faulty drone with camera AND now motor issues....

I have the same problem with my mini 3 pro. I have half of the image aout of focus! I am a professional photographer and I know when I have a problem with a lens. wish is the case!! I hope they fix it.

I know my 2 cents isn't worth much here, the OP is in touch with people that are much more experienced then I, however, I never expected the pictures or video I take with my Mini 3 Pro would even be in the ball park with pictures I've taken with my D500 and 70-200 Nikor lens.  Seems to me you could never get near the quality out of this little camera.  I'll just sit over here, sorry to interrupt.

It has nothing to do with image quality it has only to do wtih having the camera and the lens working like they should!  If I take a picture and I have half in focus and the oder half out of focus it is not image quality it is pure malfunction.

You're right, what I was saying the you can't expect razor sharp focus from a plastic lens and no focal length.

Ain't that the truth... They are getting better and better, and if you had a drone with a Sony 240p camera 10-15 years ago, you still get to immensely appreciate the quality we have today in these drones...

I'm having issue with the focus as well, but when I think that I'm dealing with a flying camera and a drone that cost me less that one of my Nikon's lenses, I tend to relax and enjoy the moment...

Hi there, we are sorry for any inconvenience. If you have a foggy lens issue, you can submit a case through the link below and send it back for further assistance. http://www.dji.com/support If you've already submitted a case, you can check the case status through this link. https://repair.dji.com/us/trace/search

So, can we expect some kinde of general solution of this problem, which is common as we  can see, ( some update or something) or we should act individualy with DJI ☹️. I just bought a new mini 3pro yesterday and made first flight today… and yes, there is some focus issues definitelly ☹️. This is fragment from video 4K 30fps.

I think  it depends if you are lucky or not to get a mini 3 pro with no focus problem... ! I have a friend that has the same drone but has no focus problem! Check out the left part of the roof how blurred it is comparing to the right side

Ok… a question for DJI Administrators… Is there any case with declared focus issues, when these recommended steps ( refresh on DJI Assistant 2, reset camera parameters, reset RC and Aircraft firmware… itc), actually help, in terms that focus issues are gone completely and permanently? Or sending unit back is the only solution?
