iPhone X’s Telephoto Lens Is Substantially Better Than That of the iPhone 7 Plus


A head-to-head comparison between the telephoto lens of the iPhone 7 and iPhone X shows that the latter’s telephoto lens is vastly superior in low-light scenarios. When Apple launched the iPhone 7 Plus in 2016, it mentioned that the phone would not switch to the secondary telephoto lens in extremely low-light scenarios and instead output an image from the primary camera only.

The company took this approach because in certain scenarios, the primary camera sensor was able to capture more details than the secondary telephoto lens. Now that the iPhone X comes with an improved telephoto lens, how exactly have things changed? As per testing from Dan Provost, the telephoto lens on the iPhone X “requires roughly 2 fewer stops of light before switching to the telephoto lens, as compared to the iPhone 7 Plus.” This makes a world of a difference in low-light as the iPhone X would continue using its telephoto lens in scenarios where the iPhone 7 Plus would just fall back on its primary sensor.

With the iPhone X, the probability of getting a 2x zoomed image from the primary sensor is a rarity. Instead, more often than not, the handset will switch to its secondary telephoto lens. As shown in the video, the iPhone X can continue using its telephoto lens at 16 lux, while the iPhone 7 Plus switched to its primary lens after the available light went below 88 lux.

The telephoto lens on the iPhone X features an f/2.4 aperture and OIS along with an improved sensor which collectively has made this improvement possible.

While the iPhone 8 Plus also features a newer telephoto sensor, it 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 conditions.

How impressed are you with the camera on the iPhone X?
