As title says my videos have certain areas on screen that seem out of focus, blurred.
It tends to be predominant on the left side of the images.
As anyone having this issues?
Any tips on how to fix or its a camera hardware problem?

Hi, Miguel Leitao. Thanks for reaching out! Please check and confirm if both occur when using either Auto-Focus or Manual Focus. We would also appreciate uploading a short clip depicting the problem so we can check it further. Many thanks and looking forward to your response.

I had exactly same problem, just it was blurry at the right side. I took several photos, of same object being at the left and right side. I've contacted the seller and he said it happened in previous models too. My A2s was exchanged and now it's sharp (of course the edges cant't be sharp with this cheap wide lenses).
So I'm sure it was the lense fault. I used an advanced 3d calculation program which shows that the center of distortion is on the left instead of the center of photo. Now it's correct, in the center.

The seller, but very experienced and one of the best in my country, so he knew what it could be.

Well the store i bought it from, went there today, and they wanted to keep the drone for 48H for making tests and see what was wrong. As it is a general apliances store, that also sell drones, i dont trust them to make tests with my drone. So i back to square one.

Hello. Thank you for your reply. Could you please let me know the name of 3D calculation software you used? Thank you.

FWIW in the past folks have solved the problem by recalibrating their gimbal. Might be worth a shot before sending it back.

I'd also love to know what 3D calculation software you used --sounds useful.

Not exactly a 3d calculation software, I described it wrong, it's photogrametry software - Agisoft Metashape. Not very useful because there is no SDK for Air2s.
But in "camera calibration" you can make  an image of the lens distortion. You can see the center (focus point) which was on the left in my case, and the biggest distortion was on the right.
