He spent over 15 years in the photography industry before joining The Verge as a deals writer in 2021.Apple always makes a big show of the latest cameras in its phones, and the major talking point of the iPhone 18 Pro is about the new variable aperture. Both the iPhone 18 Pro and Pro Max have an adjustable mechanical iris in their main camera modules to let more or less light into the sensor, allowing users to shoot at f/1.48, f/1.8, f/2.8, and f/4. You can, of course, let the camera select your aperture automatically, but the manual aperture control comes along with other new pro controls allowing you to dial in shutter speeds, manual white balance, and even manual focusing.As a whole, this is a wealth of new controls for an iPhone camera. You’d normally have to install a third-party camera app like Halide to do some of this, and now it’s all just baked into the 18 Pro’s native camera app. (It’s almost as if Apple poached a key person directly from Halide.) But I’d temper any expectations over the variable aperture being the standout feature. It’s going to be mid, at best.PreviousNext1/348 megapixels. Four selectable apertures. Image: AppleWhy? Because smartphone sensors are still pretty dang tiny, and most subjects are in reasonable focus until you get really close. And stopping down to f/4 is unlikely to blow you away with much sharper results like it does in full-size cameras or any special qualities aside from some sunstar effects in very particular lighting scenarios. In fact, due to lens diffraction, your photos might be less sharp at f/4 than f/1.8 or f/2.8. What you’re most likely to benefit from by stopping down the lens is more depth of field with close-up subjects, getting more people in focus during big group shots with plenty of light (where people aren’t all lined up together), and more flexibility in shooting video in overly bright situations (like direct sunlight). That might prove useful for those particular situations, but they’re likely to be few and far between.And smartphone sensors are small enough to already have plenty in focus at mid-range and further distances, even when shot wide open. It’s probably why other brands like Samsung and Xiaomi have experimented with variable apertures but quietly ditched them.I think the real star feature of the iPhone 18 Pro’s camera is its f/1.48 maximum aperture. Fuck stopping down, man. People love bokeh.PreviousNext1/2Selecting aperture in the iPhone Camera app. Image: AppleLast year’s Pro iPhone cameras had an f/1.7 aperture, and now being at f/1.48, the 18 Pro camera should work better in low-light as well as have a slightly shallower depth of field. Will f/1.48 be a huge difference in bokeh from f/1.7? Probably not. It’s likely to have depth of field that’s just a smidge shallower — but that’s the look that people often like.I speak from experience here, as I usually shoot on full-frame cameras and one of my go-to lenses is a 50mm with an f/1.2 maximum aperture. A lens that fast, with depth of field that shallow gives a unique look that’s easy to overuse, but it almost never fails that people swoon when I take their portrait using that lens — with that blurry, “dreamy” blur isolating them from the background. The f/1.48 of the iPhone 18 Pro is obviously not going to compare to an f/1.2 on full-frame, but f/1.2 and similarly wide apertures on big sensors is the look that people often want to emulate. It’s the whole reason Portrait Modes on smartphones came into being in the first place.The iPhone 18 Pro is likely to have a very good camera just like most top-flight smartphones have very good cameras. The added controls are exciting and fun, even if I don’t always want to be bothered with manual controls when taking quick snapshots. It’ll be nice to have them right at your fingertips without having to install a more specialized app. Just don’t be surprised if you start ignoring that aperture setting after some initial tinkering in the new phone honeymoon phase. But even long after that, f/1.48 will be the gift that should keep on giving.Follow topics and authors from this story to see more like this in your personalized homepage feed and to receive email updates.Antonio G.

The primary focus of the discussion regarding the iPhone 18 Pro’s camera is its variable aperture feature situated in the main camera module. This system incorporates an adjustable mechanical iris that allows users to control the amount of light entering the sensor, providing selectable apertures of f/1.48, f/1.8, f/2.8, and f/4. Beyond aperture control, the module integrates additional professional controls, enabling manual adjustments to shutter speeds, manual white balance, and manual focusing. This integration streamlines advanced photographic capabilities previously requiring third-party applications, suggesting a significant native enhancement to the native camera application.

Despite the introduction of these new controls, the reviewer suggests that the variable aperture mechanism may not be the most significant innovation. The rationale provided for this assessment stems from the physical constraints of smartphone sensors and the properties of lens diffraction. Because smartphone sensors are relatively small, achieving substantially sharper results by stopping down to f/4 is unlikely to surpass the performance of full-size cameras. Furthermore, the reviewer notes that due to lens diffraction, images taken at f/4 might exhibit less sharpness compared to wider apertures like f/1.8 or f/2.8.

The true distinguishing element of the camera system is considered to be the maximum aperture of f/1.48. While the reviewer notes that the difference in depth of field from the previous generation's f/1.7 aperture is likely subtle, this feature provides a slightly shallower depth of field, which is aesthetically desirable for portrait photography. The reviewer draws an analogy, noting that the look of shallow depth of field achieved by very fast, wide-aperture lenses, such as an f/1.2 on full-frame equipment, is what users often seek to emulate in smartphone photography.

In conclusion, while the added manual controls offer exciting and engaging features for photographers, the variable aperture ultimately functions as a valuable tool that enhances existing capabilities rather than being the sole revolutionary aspect of the iPhone 18 Pro camera. The f/1.48 maximum aperture, in conjunction with improved low-light performance and marginally shallower depth of field, provides a tangible benefit that remains appealing across various shooting scenarios.
