A new code leaked from inside of Google Pixel 4 Camera shows to have a telephoto lens in the second rear camera. This discredits the rumors of a wide angle lens which was predicted earlier by several tech publications. There would also be an infrared sensor on the front camera, which indicates the possibility of face unlock.
XDA-Developers were the first who came to know about this new feature. They got inside the code of Google Camera’s Super Res Zoom, which displayed hints for ‘telephoto’ lens. This is a part of the new Camera APK inside of Android Q beta 5 which could eventually make its way into the Google Pixel 4.
The telephoto lens was actually not required in a Pixel phone because if you consider the Pixel 3 phone, it does a pretty solid job with background blurs and captures great zoom shots with good depth information for all kinds of shots. That being said, maybe the telephoto lens will have its own significance for the Google Pixel 4 and we will only come to know about that when the phone launches.
The infrared sensor will be a new addition to this upcoming Pixel device, alongside the regular and wide-angle selfie cameras. The basic use of this would be ofcourse for face unlock simialr to the Face ID on iPhones. But it could also be used for augmented reality purposes that makes use of the front camera.
More than the telephoto lens, the wide angle lens is gaining more popularity and has been implemented in Galaxy S10 series and could also be seen in the 2019 iPhones.
