Looks like the newly announced DJI Mini4 Pro is your answer to a more lightweight and affordable version of the DJI Air 3, all thanks to the addition of omnidirectional obstacle avoidance feature.
And, for just $759 (the Air 3 is $1,099), you also get the same camera (48-megapixel, f/1.7) with 4K @ 100fps and 1080p @ 200fps shooting.
You also get up to 40 minutes of battery life and a maximum range of up to 20km on a single full charge. Plus, if you already have the Mini3 Pro, you can sue use the same battery.
The DJI Mini 4 Pro is not yet available in the Philippines but based on the current price of the Mini 3 Pro (Php45,990), the Mini 4 Pro will most likely be around that price.
