Apple’s upcoming iPhone 18 Pro and iPhone 18 Pro Max are expected to feature a variable aperture camera. The upgrade has been repeatedly rumored and would be a first for Apple’s smartphone lineup, but what would it actually change for everyday users?
An aperture is the opening inside a camera lens that allows light to pass through. A natural comparison would be to the pupils of your eyes, which open wider in darkness and become smaller in bright conditions.
Current iPhone cameras have an aperture fixed at a single size. To compensate for this, iPhone adjusts other settings and uses software processing to lighten or darken the image. In contrast, a variable aperture would give the camera mechanical control over the amount of light entering the camera.
The biggest improvement – and the one you’ll probably notice first – would be smoother video when shooting outdoors. In bright sunlight, the existing camera on an iPhone must capture each frame very quickly to avoid an overexposed image, which can sometimes make motion appear unnaturally sharp or choppy.
In contrast, the iPhone 18 Pro’s variable aperture camera would typically narrow the lens aperture to limit the amount of light that enters. This should prevent washed out highlights and allow the camera to record motion with a more natural blur. Photos taken in good lighting may also appear sharper, especially at the edges. Additionally, Portrait mode photos that use the “bokeh” effect should also appear more realistic, as opposed to computer rendered.
It’s still unclear whether users will control the aperture themselves or whether the iPhone will adjust it automatically. That’s a big question mark, as it should determine whether it’s a practical photography tool or a built-in feature that just makes photos and videos look better behind the scenes.
We should know the answer to this question in the coming months. Apple is expected to launch the iPhone 18 Pro and iPhone 18 Pro Max in September, alongside its first foldable iPhone.
