When it comes to compact CineWhoop-style FPV drones is quite changing to install a full-size GoPro camera due to its heavy weight. Insta360 was the camera brand that provided ultra-light cameras for 2-3″ drones. The new Hawkeye 4K Thumb camera adopts a similar design but without a built-in battery. By comparison, the Insta360 GO 2 weights 26.5g and records 2.5K@50fps videos, and the FireFly 4K Thumb weights 15.5g and records 4K@50/30fps or in Pro mode (with GyroFlow data) 4K@30fps.
The Hawkeye 4K Thumb features a native 4:3 image sensor. At 2.5K video resolution, the 4:3 mode provides 36% more pixels than the 16:9 mode. So the stabilization in 4:3 mode is much better than in 16:9 mode. The 12MP Sony sensor provides a 170° field of view. It supports 5-23V DC inputs so that you can power it from the drone’s main battery (2-5s LIPO).
The FireFly 4K Thumb camera can save gyro data while recording. The sampling rate can up to 1000Hz, which according to Hawkeye, provides the most accurate data for GyroFlow stabilization.
