- banana_giraffe 7y agoI think you're referring to so called electrically tunable lens. Most every camera these days uses an electromagnetic diaphragm to control the aperture. And yes, it's a electrically tunable lens are a thing. Optotune is one company I've heard of making hardware for the industrial space, there are probably others.
