At a glance, our lens switcher looks the same as before; we kept
it in the same spot so it doesn’t interfere with your viewfinder
and is within easy reach. Keeping the viewfinder clear of any
obstructions is one of our highest priorities.
It works similarly, too, at first glance: just keep tapping to
cycle between 1x, 2x, and 0.5x sizes.
Unfortunately, switching cameras has a bit of a delay. If you’re
composing a shot and want to compare the 0.5x and 1x lenses,
cycling past that 2x lens feels slow and clunky. No sweat. Haptic
touch (or in common parlance, long press) the lens button to bring
up our lens switcher.
This is a really clever bit of UI, very well-implemented. And part of that, as Sandofsky notes, is that it never obstructs the viewfinder.
