iPhone 18 Pro Variable Aperture vs 17 Pro: Photo Changes
The iPhone 18 Pro's main camera can switch between f/1.48, f/1.8, f/2.8 and f/4, while the iPhone 17 Pro was fixed at f/1.78. That gives more control over low-light shots, background blur and group-photo sharpness, but it applies to the main camera only and the starting price rose $100 to $1,199.
