The variable aperture isn’t the cool part of the iPhone 18 Pro’s camera

Aand 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 , 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 and 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.

Last 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.
