DJI Mini 4K
Three hundred dollars is the entire point here. Strip a Mini down to a 1/2.3-inch 12MP sensor, 8-bit 4K/30, and a downward vision system with nothing looking forward, keep the three-axis gimbal and the GPS return-to-home, and you get the cheapest genuinely stable aerial camera DJI sells. Nothing about the footage will impress anyone who has seen a 1/1.3-inch sensor at dusk, but in daylight it is sharp and level, which is more than any sub-$200 quadcopter manages. O2 transmission is rated to 10 km and holds a 720p feed rather than O4's 1080p. Treat the lack of obstacle sensing as the defining spec: this aircraft will fly into a branch at full speed without hesitating, so it belongs in open fields while you learn.

Holy Stone spent years making competent toys and then built this, which is the first of their aircraft that invites comparison with a Mini rather than with a hobby quadcopter. Three-axis brushless gimbal, a 48MP 1/2.3-inch Sony sensor, 6 km of transmission, subject tracking, built-in Remote ID and 249 grams on the nose. Reviewers have been noticeably warmer about it than about anything else in the brand's catalog. The gaps are still real: no obstacle sensing in any direction, a fixed-focus f/2.6 lens, and a measured 22 minutes against a 30-minute claim. At roughly half a Mini 4 Pro's price with a real gimbal and real Remote ID, though, it is the most credible budget alternative here.
