iPhone 18 Pro Variable Aperture vs 17 Pro: Photo Changes
As of October 2026, the iPhone 18 Pro variable aperture lets the main camera switch between f/1.48, f/1.8, f/2.8 and f/4, while the 17 Pro was fixed at f/1.78. It helps low-light shots, background blur and group photos, but covers the main camera only and costs $100 more.
