Apple has given the iPhone 18 Pro and Pro Max a variable aperture in the main camera, the first hardware change of its kind in the company鈥檚 flagship phone line. The lens can open as wide as f/1.48, compared with the previous maximum of f/1.8, and can stop down to f/1.8, f/2.8, and f/4. Apple also added manual exposure controls to the native camera app, including settings for aperture, shutter speed, white balance, and focus. The devices are $100 more expensive than last year, and higher storage tiers carry steep prices.
The practical effect of the wider aperture is limited. At f/1.48, the iPhone produces more background blur and slightly better low-light detail than at f/1.8, but the difference is subtle. The larger opening also allows Night Mode to use a shorter capture time, which reduces the chance of blur from hand movement and lessens the noise the system must process out. Apple has set the aperture to adjust automatically by default, mostly staying at f/1.8 in good light, opening to f/1.48 in dim conditions, and closing to f/4 for group photos or close-up text, where more of the frame stays sharp.
The narrower settings offer marginal gains for depth of field. At f/4, the back of a close-up subject that looks soft at f/1.48 or f/1.8 becomes sharper. Even at its widest, the phone鈥檚 f/1.48 aperture is roughly equivalent to f/5 on a full-frame camera in depth-of-field terms, so most of a scene is already in focus. The source article describes the use cases for manual aperture control as narrow.
The manual shutter speed setting changes how the camera processes images. Apple spokesperson Stephanie Ng confirmed that the camera captures a single frame in that mode rather than combining multiple frames, as it normally does. The result loses some dynamic range, though a gain map is still included when highlights are bright enough to require one. The source article notes this is one way to obtain a less-processed image from an iPhone.
Apple also added texture controls to Photographic Styles. The controls can add a film-inspired glow to highlights, overlay film grain, or soften skin. The iPhone 18 Pro and Pro Max share their dimensions with the iPhone 17 Pro closely enough that the two generations use the same cases. Inside, the phones use a revised thermal design that lets the A20 Pro chip hold full performance for longer. The foldable iPhone Duo, announced alongside the 18 Pro, arrives next month and drew more attention at Apple鈥檚 launch event.
