The Apple iPhone 11 Pro Max has three fixed lenses for .5x zoom, 1x zoom, and 2x zoom, as well as a 10x digital zoom. Photo samples of these are below. The photo quality diminishes at the 10x digital zoom level, but at that setting the iPhone could serve as a simple 10x binocular device to see distant objects a little better.

.5x Optical Zoom – Wide Angle

1x Optical Zoom

2x Optical Zoom
