iPhone 18 Pro Max features new variable aperture camera system
Apple has introduced a variable aperture feature on the main camera of the iPhone 18 Pro and Pro Max models.

How the new hardware works
The device adjusts its opening size to control light intake and focus depth. A wider opening lets in more light but keeps distant objects blurry. Narrowing the opening reduces light while keeping the entire image sharp.
Testing the camera update
Reviewers tested the black iPhone 18 Pro Max immediately after receiving it. They found the change creates a noticeable difference in photo quality. The new controls allow users to manage these settings directly.
