iPhone X's telephoto lens is much better than the one on iPhone 7 Plus

26 November 2017 3

The iPhone X features a 12-megapixel f/2.4 “telephoto” lens with optical image stabilization (OIS) as a part of the primary camera setup. This was recently compared to the 12-megapixel f/2.8, non-OIS lens present on the iPhone 7 Plus by Dan Provost from Studio Neat. Both the devices, which were first placed in a pitch black environment, were then subjected to an object in the front. The lighting conditions were then changed gradually to see whether the devices switch lenses in order to collect the light.

The experiment revealed that the iPhone X changed lenses after the light was changed twice, whereas the iPhone 7 Plus took two more levels of brightness. The telephoto lens on the camera doesn’t just help gather data for Portrait mode and portrait lighting but also handles 2x optical zoom feature. When the camera system doesn’t have enough light, it will switch back to wide angle and digital zoom to preserve the quality of the image.

Provost, after the experiment, said,

I also used the manual camera app Halide to get an ISO and shutter speed reading at the various light levels, and came to the conclusion that the iPhone X requires roughly 2 fewer stops of light before switching to the telephoto lens, as compared to the iPhone 7 Plus.

The latest iPhone 8 Plus features a newer telephoto sensor, still has the same aperture and lacks OIS as the iPhone 7 Plus. Thus, its performance is largely similar to that of its predecessor in such lighting conditions. The video is linked in the source below.
