The camera setup is versatile and complete - something you don't see on every mid-range device. The main sensor is the popular 48MP supporting pixel-binning technology and it's paired with a bright f/1.7 aperture and OIS for less shaky images. There's also a 16MP sensor coupled with an ultra-wide lens, but Motorola doesn't disclose anything besides 117-degree field of view. The EXIF data shows f/2.2 aperture, though.
The third camera on the list is the 8MP telephoto unit capable of 3x zoom, has OIS and features f/2.4 opening. It's nice to have 3x loss-less zoom at this price. Even some flagships are stopping at 2x so kudos to Motorola. After all, the company named its phone One Zoom. And lastly, the fourth camera is a 5MP depth sensor, mainly used for the bokeh-like effects when shooting portraits.
And as for the front-facing camera, Motorola has put a 25MP sensor using the Quad Pixel technology to output 6.25MP images. It's paired with f/2.0 aperture lens.
Here are some daylight shots with the main camera, the ultra-wide lens and the telephoto.
And here are two portrait samples to test out the edge detection.
