A doctor in San Diego has started using Macro mode on an iPhone 13 Pro to get a better look at the eyes of patients. The popular feature on the new iPhone Pro models doesn't require specialized hardware and is very straightforward to use, making it a fast and simple way of checking on a patient. All of which means patients shouldn't be too surprised if their next ophthalmologist visit involves an iPhone centimeters away from their face.
Macro mode is really quite neat. Without using specialized lenses - as would be the case with a DSLR - the iPhone can achieve incredible shots with a focus range of up to 2 centimeters away. While these shots are unobtainable with a regular focal length lens or camera, the iPhone 13 Pro's ultra-wide lens doubles as a software-enabled macro lens, since it has an f/1.8 aperture and a 120-degree field of view. The feature is typically used for capturing smaller objects, such as closeup shots of spiders or flowers. Essentially, if it's small, Macro mode can probably take a pretty good photo of it, adding one more tool to the iPhone 13 Pro for on-the-go photographers.
