According to Apple's press release (https://www.apple.com/pt/newsroom/2026/09/apple-debuts-iphone-18-pro-and-iphone-18-pro-max/):

Variable aperture also provides more control for creative pros by giving them the ability to manually adjust any of the four aperture settings in the Camera app, and an API is available to developers for even more control across the aperture range in their apps.

Can a DTS engineer specify the quoted API please? I can't see it anywhere in the documentation yet.

What does it mean "even more control across the aperture range"? Will it be possible to set the aperture in a 0.0-1.0 range?

27.2 Beta just came out.

However, there are no mentions of new aperture change API's.

I am confused as well.

That is correct. AVFoundation now supports aperture priority, shutter priority, and full manual exposure control through https://developer.apple.com/documentation/avfoundation/avcapturedevice/setexposuremodecustom(lensaperture:duration:iso:completionhandler:)
