The iPhone X is the pinnacle of Apple’s cameraphones. It improves on the iPhone 8 Plus camera with a superior telephoto module, which has an additional OIS system and a brighter lens (f/2.4 vs. f/2.8).
As you may know, the telephoto cameras of both the iPhone 7 Plus and 8 Plus are disabled in the dark. Instead, 2x zoom is achieved by cropping and then upscaling the image from the wide camera, leading to a soft image with less than expected detail.
So you’d think with the iPhone X’s two improvements that benefit the low-light performance, this restriction will finally be lifted. But alas…
