Firstly, I apologize for my English. I am in doubt about acquiring the Air 3 due to its camera. My question is about the quality for both filming and photos. I would like to know if the Air 3 performs well for professional work. Those who own the Air 3, could you share your camera usage experience?

I use it several times a week for professional imagery.

I have no complaints over the quality. The drone does well when its sunny, cloudy, and nighttime.

Hi, there. Thank you for your interest. DJI Air 3 has improved the camera system, video transmission system, vision sensing system, flight time, and intelligent features. To learn more, you may visit this link. We hope you get the best feedback that you may need. Thank you for your support.

I have got the drone a few days ago, and I'm definitely not complaining about the quality.
It is very sharp, and allows for extensive color grading with 10-bit DLog-M.
Absolutely good enough for most professional use cases. At night, it isn't as good as the Mavic 3, but it alright for most shots!

Depends...
I work with Air 3 in commercials...is fine, but not super...a bigger sensor like Mavic 3 is felt different in editing.
So...for small commercials, weddings, TV broadcast, will work.
For some bigger like movie creator, go to Mavic 3 series.

I've had Air 3 for a month and in my opinion the photo quality is terrible. Not average, not acceptable - just terrible. My old Mavic Pro 1 took better photos than the new Air 3. In the video it's not very bad, but the autofocus works very poorly. Paying $1.5k for a drone, I would expect more respect for users from the manufacturer.
