VR: How It Works Nikon vibration reduction lenses employ two angular velocity sensors: one detects pitch (horizontal motion); the other detects yaw (vertical motion), and working together, they both detect diagonal motion. Every 1/1,000 second the sensors interpret camera movement and send angular velocity data to a microcomputer in the lens. The microcomputer figures out how much compensation is needed to offset the camera's shake and sends that information to two voice coil motors that move selected lens elements to compensate for the detected motion. You might think of VR as an imaging technology equivalent of Newton's Third Law: For every action there's an equal and opposite reaction. With one important exception: There are times when you don't want your VR lens to compensate for motion—specifically, when you're panning the camera. So built into the computer's programming is an algorithm that allows for big motion. In other words, when you pan, the VR system knows it's what you want to do, and it won't try to defeat your intention. Quote Link to comment Share on other sites More sharing options...
