Capture your best shot with smartphone dual cameras

The most advanced current camera setup is currently found in the Huawei P20 Pro that has three cameras with a total of 68 megapixels. There is a RGB 40 megapixel lens, a 20 megapixel monochrome lens, and an 8 megapixel 3x optical zoom lens. With this combination you get 3x optical zoom, hybrid 5x zoom, portrait support, monochrome modes, and more.

With the P20 and P20 Pro, Huawei not only gives you monochrome support with the second camera, but gives you some options within monochrome mode.
