What is the news?
Apple is testing 2 upgrades for the rear cameras in its upcoming iPhone 18 Pro and iPhone 18 Pro Max, which could completely change night photography. These include a variable aperture main camera and a wide aperture telephoto lens, which are aimed at improving photo quality in different lighting conditions. This information has come from a reliable leaker named Digital Chat Station on Weibo.
There will be a change in aperture
MacRumors reported that Apple is developing a main camera that can physically adjust the aperture. Current iPhones have a fixed aperture, whereas the light reaching the sensor can be controlled by increasing or decreasing the variable aperture. In low light the lens can open wider to capture more detail and reduce noise. May be narrower to avoid overexposure in brightly lit scenes.
This change will be available for the first time
If this feature is introduced, it will be the first time that Apple will use variable aperture technology in an iPhone. Recent Pro models from iPhone 14 Pro to 17 Pro have used a fixed F/1.78 aperture. Variable aperture is not a new technology for smartphones. Samsung adopted this technology for a short time in the Galaxy S9 and S10 series, which was later removed.
