On the back of the iPhone XR you'll find a single optically stabilised wide-angle 12-megapixel f/1.8 camera jutting out slightly from the glass. As there is no secondary telephoto sensor you can no longer optically zoom and jump to '2x', and the iPhone XR also handles portrait mode shots differently.

Does iPhone XR have wide-angle lens?

The iPhone XR has a 12-megapixel wide-angle lens with an f1. 8 aperture and optical image stabilization. This happens to be the iPhone XS' main lens too -- the one you'll use to take the majority of your shots that aren't in portrait mode or zoom.
