When the dual-lens system switches to the telephoto lens?
Apple introduced the dual lens camera module with the iPhone 7 Plus in 2016, allowing users to capture better low light shots, including photos with 2x zoom. But the camera does not always switch to the wide angle lens to the telephoto lens, depending on the lighting conditions. There were cases in which the phone simply cropped the photo from the wide angle lens.
iPhone 8 Plus and iPhone X offer an improved sensor with wider aperture, and even OIS in the iPhone X. A test by StudioNeat has measured how much light is required before the telephoto lens is enabled in the iPhone X.
An object was placed on a white backdrop, while two LED studio lights were placed on both sides of it. The phones (X, and 7 Plus) were mounted on tripods, and starting from a completely dark room, the testers slowly raised the light to observe both cameras.
The conclusion is pretty clear – the iPhone X requires less time and light before switching from the wide angle to the telephoto lens. This in turn results in faster shutter speeds and lower level of iOS compared with the iPhone 7 Plus.
It’s clear that the OIS really helps in the iPhone X, and this is the phone you should buy if you want the best possible photo and video quality.
