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.
