Korean media ETNews published a blog post yesterday, reporting that the variable aperture actuator, the core imaging component of Apple's iPhone 18 Pro series, has entered mass production. According to ET News supply chain, China's Sunyu Optics has begun production of actuators, and LG Innotech is also deploying special equipment at the Gumi plant in South Korea to prepare for large-scale mass production. Variable aperture is the most important hardware upgrade for iPhone imaging systems in recent years. The lens aperture of traditional mobile phones is fixed, and the amount of light entering cannot be physically adjusted. The variable aperture moves the lens component through the actuator to physically change the aperture size, allowing the user to accurately control the depth of field.
