The rumored iPhone 16 Capture Button may detect multiple pressure levels, similar to a dedicated camera’s two-stage shutter button.

MacRumors previously reported a new Capture Button on iPhone 16 models. Bloomberg’s Mark Gurman said it would record video. The Information reported additional controls, including swiping left or right to zoom and lightly pressing the button to focus on a subject.

Weibo user Instant Digital reported that the Capture Button’s main function would be to take photos or start video recording, while a light press would adjust focus. This resembles the two-stage shutter release on many DSLR and mirrorless cameras: a half-press locks focus or exposure before a full press takes the photo.

Earlier reports place the Capture Button on the lower right of iPhone 16, replacing the US models’ mmWave antenna, which would move below the volume and Action buttons on the left.
