The standout feature of the iPhone 18 Pro’s camera isn’t its variable aperture.
Apple always makes a splash with the latest camera features in its phones, and the iPhone 18 Pro is no exception, boasting a new variable aperture. Both the iPhone 18 Pro and Pro Max come equipped with an adjustable mechanical iris in their main camera modules, allowing users to shoot at f/1.48, f/1.8, f/2.8, and f/4. While you can let the camera choose the aperture automatically, the manual control is paired with other pro features that let you adjust shutter speeds, white balance, and even focus manually.
I had the chance to try out these new devices at the iPhone keynote at Apple Park. Overall, the new controls for the iPhone camera are impressive. Previously, you’d need a third-party app to access such features, but now they’re integrated into the native camera app of the 18 Pro. It feels like Apple has taken inspiration from some of the best features of those apps. However, I’d advise tempering expectations about the variable aperture being the standout feature; it’s likely to be just average.
Why is that? Smartphone sensors are still quite small, and most subjects remain in focus unless you’re shooting very close up. Stopping down to f/4 probably won’t yield the dramatic sharpness you’d expect from larger cameras, and you might even find that your photos are less sharp at f/4 due to lens diffraction. The real benefits of stopping down are more depth of field for close-up shots, better focus in group photos with ample light, and improved video flexibility in bright conditions. While these situations can be useful, they’re not likely to come up all that often.
Smartphone sensors are already capable of keeping plenty in focus at midrange and further distances, even when shot wide open. This might explain why other brands like Samsung and Xiaomi have tried variable apertures but ultimately moved away from them.
The true highlight of the iPhone 18 Pro’s camera is its f/1.48 maximum aperture. Forget about stopping down; people love that bokeh effect.
Last year’s Pro iPhone cameras had an f/1.7 aperture, and with the new f/1.48, the 18 Pro should perform better in low light and offer a slightly shallower depth of field. Will the difference in bokeh between f/1.48 and f/1.7 be significant? Probably not. The depth of field will be just a touch shallower, but that’s the aesthetic many people appreciate.
Speaking from experience, I often shoot with full-frame cameras, and one of my favorite lenses has an f/1.2 maximum aperture. That kind of lens creates a unique look that can be overused, but it never fails to impress when I take portraits with that dreamy blur isolating the subject from the background. While the f/1.48 of the iPhone 18 Pro won’t match the f/1.2 on a full-frame camera, it captures the essence of the look that many want to achieve. This is precisely why Portrait Modes on smartphones became popular.
The iPhone 18 Pro is set to have an excellent camera, much like other high-end smartphones. The added controls are exciting and fun, even if I sometimes prefer not to fiddle with manual settings for quick snaps. It’s great to have those options readily available without needing a specialized app. Just don’t be surprised if you find yourself ignoring the aperture setting after the initial excitement wears off. However, even long after that, the f/1.48 aperture will continue to deliver impressive results.
