According to Baidu Encyclopedia, VR means anti-shake. On the lens, "VRNO" means the anti-shake function is on, and "VROFF" means the anti-shake function is off. VR anti-shake technology is an optical technology that improves image blur caused by camera shake. It enables fast shooting when slowing down the shutter speed by three stops, allowing clear photos to be taken using telephoto lenses. When a photographer shoots a moving object, the system will even automatically detect the movement of the camera and activate the anti-shake system.
