iPhone 18 Pro adds variable aperture camera, keeps $100 premium over 17 Pro

Apple's iPhone 18 Pro shares nearly identical dimensions, weight and 6.3-inch OLED displays with last year's 17 Pro, but adds a variable aperture camera for exposure control, a slightly smaller Dynamic Island supporting three Live Activities, and a redesigned vapor cooling chamber. It costs roughly $100 more than the 17 Pro and drops the orange color option available on the prior model.
