Score: 74/100Rankings
The Apexcam M80 AIR is a budget-friendly 4K action camera that offers dual batteries, a wide 170° view and waterproof capability, making it suitable for casual outdoor shooting. Its electronic stabilization and Wi-Fi are adequate but fall short of higher-end competitors.
The SJ4000 Pro-Grade delivers 4K video with 3-axis EIS, dual removable batteries and waterproof protection, making it a solid budget option, though its limited frame rates, short 4K battery life and lack of external audio inputs keep it from professional use.
