The upcoming iPhone 17 series is set to get a major update that is bound to take smartphone photography to the next level. Reports have surfaced which claim that Apple will be incorporating a feature typically reserved for DSLRs, or mirrorless cameras, with interchangeable lenses — a variable aperture.
If true, this innovation promises to give photographers greater control over image blurriness, bringing iPhone photography closer to the capabilities of DSLRs and mirrorless cameras.
Variable apertures allow photographers to adjust the size of the aperture—the small hole through which light passes to reach the camera sensor. On dedicated cameras, this adjustment is made via a series of blades that form a circle, changing size to let more or less light through.
This feature is largely absent in smartphones, which usually have a fixed aperture. For instance, the iPhone 15 Pro uses fixed apertures of f/1.78 for its Main and Telephoto sensors and f/2.2 for the ultra-wide sensor.
Improving Control Over Light and Focus
Adjusting the aperture impacts two critical aspects of photography: the amount of light that reaches the sensor and the depth of field (how much of the image is in focus).
A larger aperture (low f-number) allows more light to hit the sensor, which is beneficial in low-light conditions. Conversely, a smaller aperture (high f-number) lets in less light but increases the depth of field, making more of the scene appear in focus.
This control is particularly valuable for achieving the bokeh effect, where the subject is in sharp focus while the background is beautifully blurred. Currently, iPhones achieve this effect through computational photography, using software to simulate the bokeh rather than adjusting the hardware. The introduction of a variable aperture would allow for genuine in-camera bokeh, offering more natural and precise results.
Which iPhones will get variable aperture?
According to sources from The Information, Apple plans to include adjustable apertures in at least one model of the iPhone 17 range. Given Apple’s history of debuting advanced photographic features in its Pro models, it’s likely that the iPhone 17 Pro and Pro Max will be the first to showcase this technology.
Apple is not the first to experiment with variable apertures in smartphones. The Xiaomi 14 Plus, for example, offers a variable aperture ranging from f/1.42 to f/4.0.
However, Apple's entry into this space could set a new standard, leveraging its expertise in both hardware and software to deliver superior performance and user experience.
The inclusion of a variable aperture in the iPhone 17 represents a significant leap forward in smartphone photography. By offering more control over light and focus, Apple is poised to narrow the gap between smartphone cameras and dedicated cameras, making the iPhone an even more powerful tool for photographers.
As with past innovations, it’s expected that this feature will initially be available in the Pro models before potentially trickling down to the standard editions in future releases. This move underscores Apple’s commitment to pushing the boundaries of what’s possible in mobile photography.
