It is the end of July 2024, and in more than a month, we will see Apple's annual flagship iPhone 16 series mobile phones. However, due to the small upgrade of this product, many friends may have started waiting for the iPhone 17 Pro.

Recently, foreign media broke the news that Apple is planning to equip the iPhone 17 Pro with an adjustable aperture. It is understood that an adjustable aperture refers to a circular opening in the camera lens that can be adjusted in size, which controls the amount of light entering the camera. The size of the aperture is usually expressed in f-numbers. The smaller the f-number, the larger the aperture and the more light enters the camera; the larger the f-number, the smaller the aperture and the less light enters the camera.

It is important for mobile phones to be equipped with adjustable apertures. A larger aperture allows more light to enter the camera, which is very beneficial for shooting in low-light environments, reducing noise and improving image quality. In addition, by adjusting the aperture size, users can control the depth of field of the photo, that is, the degree of background blur. A large aperture can produce a shallow depth of field, making the subject stand out and the background blurred; a small aperture can achieve a greater depth of field, making both the foreground and the background clear.
