Yes, the iPhone 11 does have a 0.5x camera. The ultra wide-angle lens allows you to capture double the field of view for expansive landscape shots. Read on to learn how the 0.5x lens aperture compares to the main camera and why the wider perspective is useful for certain types of photography.
The iPhone 11 features a dual-camera system with both a standard wide-angle lens and an ultra wide-angle lens. The ultra wide-angle lens provides a 0.5x zoom out compared to the primary camera. In other words, it allows you to capture much wider field of view photos – about 120 degrees compared to the traditional wide-angle lens which captures around 85 degrees field of view.
So when people refer to a 0.5x camera, they are talking about this ultra wide-angle lens on the iPhone 11. The 0.5x denotes the wider perspective you can capture compared to the 1x standard wide-angle lens. While the primary wide-angle lens has an aperture of f/1.8, the 0.5x ultra wide-angle lens has a slightly smaller aperture of f/2.4. This means it lets in a bit less light, but provides that dramatically expanded field of view that allows you to pack a lot more into each photo.
In summary, yes the iPhone 11 does have a 0.5x camera. It’s the ultra wide-angle lens that provides double the field of view compared to the main wide-angle camera. This provides a lot more flexibility for taking beautiful landscape shots, architecture photos, and when you simply want to fit more content into each frame.
