The DJI Air 2S is absolutely still worth buying in 2024 at $699-750. The 1-inch CMOS sensor produces excellent images with 20 megapixels and 12.6 stops of dynamic range -- that sensor quality hasn't changed. 5.4K/30fps video is more resolution than most people actually use.
What the Air 3 adds: 70mm telephoto camera (the biggest upgrade), 4K/100fps, omnidirectional obstacle avoidance, better low-light on the wide camera, and 46-minute flight time vs 31 minutes.
If telephoto is important to your work, the Air 3 at $1,099 is worth the premium. If you mainly shoot landscape and wide aerial footage, the Air 2S 1-inch sensor is still one of the best in its price range and image quality won't hold you back. At $699-750 it's genuinely excellent value.
