zoom in and out on iPhone 11
The camera zoom control has been changed on the iPhone 11 Camera. If you have an iPhone 11, there will be two buttons: .5x and 1x. .5x is the new ultra-wide camera and 1x is the standard default camera. If you have an iPhone 11 Pro, there is a third button for 2x zoom. You can tap the button to jump to that zoom level. However, you can also slide horizontally on those buttons to open a zoom wheel. This allows you to select intermediate zoom levels and also displays the equivalent focal length in 35mm film. You can also pinch and zoom with two fingers to adjust zoom, and switch between lenses, but the focal length wheel will not be shown. If you have changed to a custom zoom level and want to jump back to 1x, just press the center button
