I owned a Mavic 2 PRO, and later an Air 2s. I found the Air 2s was a major step up from the M2 Pro. Now, I got an Air 3s. I have to say that after some comparative tests using test patterns I found the Air 2s is significantly better than the Air 3s at the comparable frame rate, resolution and mode (HLG or D-log) and default style for the 3s. The Air 3s in HLG mode has issues with the blue dot over a white grid on black background. The grid bleeds into the blue dot creating dark artefacts. This does not happen on the 3s D-log setting and most of all it does not happen in any mode on the 2s. But maybe worse than that is the moire issue on vertical lines. It is much worse than the 2s, again at default style setting. That, I am sure has to do with the encoder having compression issues because it literally flashes terrible artefacts on the patterns. I believe that DJI pushed the "sharpness" on the 3s to at least appear to produce level of details shown by the Air 2s. I sure hope going forward, DJI will improve that (higher efficiency) encoder to manage the moire effects better. Pretty disappointing to say the least. However there are two aspects that the 3s is better: 1) the optics are a bit better showing no apparent chromatic aberration. 2) The 3s does MUCH better in shadows, and shadow details with much less noise in the shadows even in HLG mode. That is probably the most important and most significant video quality improvement over the 2s. I suspect that if the 3s 1" sensor is only 12MP then the pixels are much larger which is most likely responsible to produce a wider dynamic range. 3s HLG video with extreme range subjects clearly shows that off and is much better than the 2s. Also, 4K (Dlog and HLG) at 30 frames records at around 80Mb/s while at 60 frames about 90Mb/s. Both, nowhere near 130Mb/s. The Air2s recorded 10-bit video at about 103Mb/s at 30 frames.
My conclusions: Since the moire issue and the blue color "bleed artefact" in HLG are most likely solvable by firmware over time, yet are quite disappointing at this point, the dynamic range with much lower noise alone makes the Air3s as a camera drone clearly a step up over the 2s and the drone itself most definitely is.

I think you’ll find that while you might think and hope that moire will be sorted with firmware, you should refer to Mavic pro 3 which has a lot worse Aliasing moire in certain situations and 200mbps has not sorted this out, in fact bitrate has nothing to do with aliasing moire and if it had then surely there would be less on the M3 pro. Aliasing/ moire are pretty easy to sort in post and it’s pretty easy to know when it’s likely to occur.
I do agree that shadow detail on the air3 s is exceptionally good and we all know that bitrate is directly associated with detail , and I do believe quality will improve with firmware updates as it has in all dji cameras. |
