Apple will be holding an event today starting at 10 a.m. Pacific Time, with the company expected to unveil new iPhones and much more.

Ahead of the event, Apple's new CEO John Ternus just shared a mysterious teaser video. The short clip appears to show a beam of light that is shining onto the edge of an iPhone. The light is coming from a hexagonal shape that changes size, which could hint at the iPhone 18 Pro's rumored mechanical aperture upgrade.

The main 48-megapixel Fusion camera on the iPhone 18 Pro and/or iPhone 18 Pro Max is rumored to have a variable aperture, which would allow users to control the amount of light that passes through the camera's lens and reaches the sensor. This would provide greater control over depth of field. However, given that iPhones have smaller image sensors due to smartphone size constraints, it is unclear exactly how meaningful this improvement would be.

In addition to the iPhone 18 Pro models, Apple is expected to unveil its first-ever foldable iPhone today. The device is reportedly named iPhone Duo.

Ternus became Apple's CEO on September 1, succeeding Tim Cook, who is now the company's executive chairman. Ternus joined Apple in 2001, became a VP of hardware engineering in 2013, and became SVP of hardware engineering in 2021.

MacRumors is in attendance at Steve Jobs Theater and will be providing live coverage of Apple's event today, so stay tuned. It will be a very busy day.

Can't tell if the round body on the bottom is a camera lens up close or an outline of a folding point. of a folding phone.
 
Sounds intriguing. I upgrade every year, which seems to upset some people around here. My only question is how high Apple thinks it can push prices before people finally flinch. Then again, App Store revenue and leasing plans make sticker shock disappear one monthly payment at a time. 😏

Thank you, MacRumors, for being the one site to point out the inconvenient matter of physics. An f/1.8—4.0 variable aperture on a sensor as small as the one in a phone amounts to basically marketing puffery. The software-defined bokeh, despite its foibles (mis-identified subjects, weird edges, etc.) is still the better solution to separating subject and background on phone snapshots.

Out of 8 billion people in the world and a smartphone market that’s estimated at 1.2 billion units sold in 2025, they “only” have to sell 200 million devices to be roughly on track with the prior year. 80% of the people in the market for a smartphone this year could flinch (or choose Android) and they’d still clear over 200 million.
