What is variable aperture on a phone?
The aperture of a lens (it is the lens that has an aperture, not the camera) simply refers to how open or closed the lens’s diaphragm is, which is where the light enters through and then hits the camera’s sensor.
Most phones come with cameras that have fixed apertures. For example, the Pixel 7 Pro’s main camera has an aperture of f/1.9. The lower that number after the “f/” is the more light the sensor can capture. This number also affects how shallow the focus is, and how blurred out the background and foreground are.
So, when a phone’s camera has a variable aperture it means that the lens can change between multiple apertures, resulting in different looks and control over one of the main elements that affects how much light the camera can capture.
While lenses with variable aperture are still quite rare in phones, there are already examples such as the Xiaomi 13 Ultra that have shown what this tech could do. For now, this tech is still mostly seen implemented by Chinese phone manufacturers, but there is a good possibility we will see it in more globalized models like the iPhones and Galaxies out there in the years to come.
