The real story of the iPhone 18 Pro's camera

In the first few weeks of his tenure, Apple CEO John Ternus was spotted at the Emmys, wearing a tuxedo with an iPhone Duo in his breast pocket, turning the phone sideways to take selfies, and posing for photos with celebrities. The Vergecast hosts note the contrast with Tim Cook’s usual brief, stiff appearances. Ternus, who previously oversaw hardware engineering, comes across as a normal human who might almost pass as cool. But the substance of the episode is not about CEO vibes — it’s about what the iPhone 18 Pro’s camera actually does, and what the hype gets wrong.

The variable aperture is not the real story

The flashiest hardware change is a variable aperture on the main lens, which can stop down from f/1.8 to f/4. But both reviewers — Allison Johnson and David Pierce — found themselves mostly shooting at the default wide-open setting. The lens is optimized for f/1.8, and on a tiny sensor, stopping down rarely produces a meaningful difference in depth of field. In auto mode, the phone only drops to f/4 in specific situations like group shots. The variable aperture is better understood as infrastructure for a future where Apple might use a larger sensor (a 1-inch type, for example) where stopping down would actually help keep more of the scene in focus. For now, it is a test bed.
