Camera lenses.

On an iPhone with several cameras, GPS Camera 55 opens on the automatic camera (AUTO) at 1x: the whole zoom range from the ultra-wide to the longest lens, with iOS choosing the lens as you zoom. To take every photo through the same optics instead, pick a single focal length in the lens selector at the bottom of the lens strip — the strip opens from the zoom chip on the left edge of the viewfinder, or from the camera button at the top of the screen.

Where to find it

  • Lenses and zoom — the zoom chip, the lens strip and its stops, AUTO against one fixed lens, how far each one zooms, and remembering the lens you used last.
  • Focus — the AF button, locking focus, a saved focus you can return to, and setting focus by hand.
  • Shutter timer — the camera sheet, the countdown, and why a remote release never waits.
  • Viewfinder controls — the settings behind all of it, plus the viewfinder gestures, the black screen and the video light.

Historical note: versions before 5.3 offered a camera device list in the navigation bar (Single camera: Ultra Wide, Wide-Angle, Telephoto; Combined: Dual, Dual Wide, Triple). That list is gone — the lens selector on the strip and the flip-camera button replace it, and every lens is available in the free app.
