Four drones, four different constraints
The Mini 4 Pro keeps weight and cost down while still offering RAW, D-Log M and omnidirectional sensing. The Mini 5 Pro keeps the compact body but adds a 1-inch main camera and better night sensing. The Air 3S gives up pocketability for a dual-camera system and a heavier, steadier airframe. The Mavic 4 Pro is the production tier: a 4/3 Hasselblad main camera, two tele cameras and an Infinity gimbal.
Extra lenses are the real step up
Sensor size is only half the decision. Both Minis give you a single 24 mm-equivalent view, with the Mini 5 Pro moving to a 1-inch sensor. The Air 3S adds a 70 mm-equivalent lens, so you can change the framing without flying closer. The Mavic 4 Pro goes further with 24, 70 and 168 mm-equivalent views. Longer lenses help with scenery, vehicles, architecture and keeping a safe distance, but they add cost, weight and more files to manage.
In low light, the 1-inch sensors in the Mini 5 Pro and Air 3S have an advantage around sunset, in shadows and under high-contrast skies. The Mini 4 Pro does best in good light. The Mavic 4 Pro's 4/3 sensor and 6K recording leave the most room for cropping and grading. If you mostly post social video, the top tier is hard to justify.
Weight, wind and sensing
The Air 3S (724 g) and Mavic 4 Pro (1,063 g) are heavier, faster platforms that generally sit more steadily in wind, but they need more space in the bag and more attention to local operating categories. The two Minis fit small kits and are easy to carry all day. Keep standard and Plus battery figures apart when you compare: the Plus pack changes weight and, in some places, the rules.
All four have omnidirectional sensing. The Mini 5 Pro and Air 3S add forward LiDAR, and the Mavic 4 Pro pairs night-capable sensing with its own navigation system, while the Mini 4 Pro relies on vision sensors that work best in decent light. None of them detects every wire or branch.
The body price is not the full cost
Controllers, batteries, chargers, storage and cases can reshuffle the price ladder, and official prices and availability differ sharply by market. The Mini 4 Pro wins on value when its camera is good enough. The Air 3S earns its premium through the second lens. The Mavic 4 Pro pays back only when its three cameras and production features get regular use. Rated flight times and transmission ranges are manufacturer maximums and drop in wind, cold and interference.
