As the world's first dual-lens action camera, the SJ20 Dual Lens comes with a powerful night-specific lens. Thanks to its large F1.3 aperture, the amount of light intake is more than twice that of other sports cameras currently available! You can switch to the night lens with just a flick of a button and record your masterful scripts in dimly lit scenes! https://www.sjcam.com/cameras/action-cameras/sj20-dual-lens/
