Are 4 Rear Cameras On A Smartphone Really Necessary?

What in God’s name will I use 4 rear cameras on a smartphone for? Are they not all taking thesame picture?

First, Huawei and LG both issued unique 3 rear camera setups, then Samsung decided three wasn’t enough, launching the quad-camera Galaxy A9 2018 last month. Adding a quad-camera setup to a non-flagship is bold.

Samsung thought we could do with one more rear camera when it launched the Galaxy A9 2018 last month, offering a quad-camera setup. In addition to the expected standard, super-wide, and telephoto cameras, the Korean company tossed in a 5MP depth sensor.

It’s an interesting move, because super-wide and telephoto cameras can generally supply depth information anyway. In fact, the Galaxy Note 8, Galaxy S9 Plus, and Galaxy Note 9 can all create Live Focus images with the aid of a telephoto camera. This could be a case of a depth sensor being used to obtain even more detailed depth maps (for better portraits and bokeh effects).

The Galaxy A9’s quad-camera setup might not be the only solution, as other brands could conceivably swap out that depth sensor for a monochrome camera, a low-light camera or another telephoto snapper.

Do you think 4 cameras is necessary?
