GoKawiiliFixit teardown reveals iPhone 18 Pro's variable aperture camera is unrepairable if broken
iFixit's teardown of the iPhone 18 Pro and Pro Max exposes the new variable aperture lens, which uses six overlapping blades thinner than a human hair to control light via a magnetic mechanism. The site praises the engineering that fits this system into the same camera footprint as last year's model, but warns the mechanism is essentially impossible to repair if it fails.
