SuperRes Zoom with telephoto camera
In the Pixel 4 and 4 XL, the new smartphone now packs it with 2 rear camera with 12.2-megapixel f/1.7 main, 16-megapixel f/2.4 telephoto and a front 8-megapixel selfie cameras. It still lacks a wide angle camera that is already present on a number of high end smartphones. As for video, the cameras can handle 4K at up to 30 fps, and 1080p at 120 fps.
To achieve the optimum picture quality, the Pixel uses a combination of 2X optical zoom on the second camera + software Super Res Zoom to deliver sharper pictures than before. To zoom, just pinch on the view finder and it can zoom up to 8x. We supposed that is a hybrid zoom with optial of 2X.

We used the 8X hybrid zoom to focus on the building structure.
It can be easily observed that the lines are well defined as compared to previous Pixel 3 XL.
