Pretty much what the title says! I have had issue after issue, and I picked up a new air 2s today and yet again I am having issues! This one has a strange sound from the internal fan motor! https://www.iwmetservice.co.uk/wp-content/uploads/pollen/video-1638300481.mp4?_t=1638300734
Is this something I can just put up with, I mean will it eventually cause an issue or is it OK?

Completely Normal sound to me. The fan is running that's a pretty simple observation.

To be honest it sounds very different to all the other ones (bar one). The others just hissed whereas this buzzes. Maybe the others just had superior fans? I mean as in quality or something? Maybe im just getting OTT now after so much bad luck!

Thanks for the reply

Hi Islandvisions, I'm sorry to hear about your confusion. Could you please check if there is an error message prompt in your app? Normally, if there is an issue with the drone, there will be an error message prompt to let you know. Thanks.

If you've had 8 replacements, there's probably nothing that you could put up with.

Having a genuine problem that needs replacing is uncommon, but it happens.
Having it happen twice would be bad luck and very rare.
Having it happen 8 times is unbelievable and indicates that there's a problem with the person involved, not the drones.

What an arrogant comment!!!!!
The drones that were faulty were inspected and tested and found to be faulty!!!! How dare you accuse me of being the problem!!!! You absolute a-hole!!!!
Oh and for your information I have been professionally flying drones and aircraft for over 10 years! Also I currently own a DJI mini 2, a Mavic Pro and a Mavic pro 2 and none of these have any faults like I have reported, also each one of my air 2s's had their own unique fault!

1st arrived damaged, 2nd kept losing signal mid flight, 3rd was completely blurred on rght of lens, 4th had a larged blurred patch mid upper image/video, 5th had a noise from the internal fan motor that sounded like a dying cat and was so extremely loud, also emitted a strange smell that resembled a burnt out clutch in a car, 6th had a big blurred patch centre/lower right (i uploaded pics of this before), 7th had 2 prop motors sounding absolutely awful and got extremely hot even after just 5 minutes flying time, and this one 8 which I have discovered has a slightly blurred patch on screen near center right but I can cope with it and a sight buzzing with the internal fan motor, but as it was only ever so slight I thought I would come here to ask people opinions, not be judged!!!!!

Oh and I thought I should also add that I took images with the blurred lens ones along with recording the sounds of the bad motors, all of which I will be happy to upload, just to prove my point that you shouldn't judge someone without knowing the facts first abd also to prove you completely and absolutely wrong!!!

Don't bother uploading anything.
I flat out don't believe that 7 drones in a row were faulty.
If the company had that many problems with quality control, they would have never got to the place they have in the market.

I, 2 3 .... perhaps, but past that it's pointing to you.
Do you have similar problems with other items you buy?

Of course you wont believe it, so I will upload the clips and photos to prove you wrong. This may take a while to get them all in one place.
I will start with the pics as I know where I saved them.

No way that is normal! Another with a completely out of focus patch! Problem is that I need this drone for high photo quality as they will be printed and having something like that is no use to me at all.
I am now beginning to realise there is a theme here and I think no matter what I do there is always going to be something like this. Even my DJI mini 2 is way sharper with no bad spots. Just a shame the res isn't so high on it.

If you want to check image quality, do it with a subject that has hard detail rather than the soft detail of a million distant thin twigs.
It's hard to know if that's actually a lens or focus issue or simply compression artifacts.
Shoot a well lit house wall from 20 ft or something like that and then check for sharp detail.

Was that the full image you posted, or just a zoomed in section?
It only measures 1500 x 1000 pixels so it's not a full-size image.
Are you looking at the actual full-size image from the SD card or a cached thumbnail?


I am now beginning to realise there is a theme here and I think no matter what I do there is always going to be something like this.
Hmm ... didn't someone suggest something like that already?

There wouldn't be compression artefacts as I used a DNG file and even though I converted to jpeg to upload, it wouldn't compress enough to cause any issues first time round.
The images are reduced in size to upload, but the cropped one is a 100% crop on the previous image and on this one.  

There is absolutely no way this is normal.

I have added a third image so you can see the normal, high quality sharpness vs the blurred strangeness on the right.

I have uploaded a third image so you can compare the amazing quality to the left and the horrible, fuzzy blurred area to the right.

I've noticed these blurred patches on my photos as well. Haven't been able to come up with a better solution than to apply sharpness/clarity locally, using radial filter in Lightroom.

Ahh
You would have thought that they would have picked up on this as it is clearly a quality control issue.
I have had multiple ones that have had a patch like this and not always in the same place either, and I have found that if you managed to focus on the exact spot when taking a photo, the rest of the image ends up being out of focus!

I think I saw this issue being mentioned here at least 10 times already, with multiple photos being posted from various users to provide proof. No official statement came from DJI though.
What saddens me is that these patches appear even on top-down shots, where depth of field isn't that relevant, yet the blurry parts still remain quite visible.

Meanwhile, if you are so convinced that the camera has problems producing a properly focused image, you could confirm that by test shooting a well lit house wall at close range.
But only if you really want to see what the problem is.

To be honest it shows very very clearly on just normal shots, and I have sent the images to a "drone doctor" who confirms that he has had multiple people report the same issue and also confirms that my images are very much in line with those too and that the issue isn't sensor related but poorly manufactured lens elements. He suggests I send it back and try and order one from the newer stock, although he doesn't say how I can do that last part!

Then why show the shots you did as your example?
Wouldn't it make more sense to clearly see the extent of the weird softness without all the distraction of all that distant soft detail?
But if a "drone doctor" (whatever that is) has commented ......

I don't see issues with the posted images. But then they may not be looking the same on my pc. Or my old eyes cannot tell the difference.

On the third image I do see blurs on the left as well, but mostly on houses of the same tan/beige color. The high contrast white and black houses look good all over the image. Again ... just my eyes.

To be totally honest I am surprised this isn't extremely obvious to some people, whereas others can see it clearly.
I am a professional photographer of over 20 years and I know when there is an image problem, im not just being difficult or trying to make a problem when there isn't one.
Also this (as I have now found out) is a common fault and many, many people are reporting the same issue, including on this thread too! So why I am not being believed by some, despite the clear issue with the image is beyond me.

I do Apple tech support and I can personally attest to the fact that sometimes, albeit rare, the consumer will get faulty hardware after faulty hardware after even more faulty hardware.  If I didn't see the diagnostics with my own two eyes I would not have believed the same consumer can have so many problems.  Apple, like DJI, has pretty darn good hardware that most consumers will never have an issue with.  But there is always an outlier and your case sounds like one.

Best not to get into spats over it here though.

All that said, there are cases where user error (or unfeasible expectations) cause multiple call ins.  So, in the end, only you know which category you are in.  An outlier in the statistics, or the latter.  As deep as you're into these problems, consider keeping close contact with DJI Support and follow their lead.  Yes, you can get good advice and opinions here but as you have discovered there is also the troll factor.

That's great! Can you please test the lack of blurred patches a bit more extensively, maybe do a couple of shots and post them here? Sounds like too good to be true, but still hoping.
