We’re already there, I think. For the bigger cameras (with no added hardware), it’s optical zoom up to a point, then then digital zoom beyond that. Mainly because they’ve got the one optical path and once they go out of the bounds of that, there’s nothing else but digital.Or, at least specify the difference between "digital" and "optical" zoom
When cell phones had only one fixed focal length camera, the “optical up to a point” was just that one focal length
I think it just takes a recognition that devices with three fixed focal lengths are different in real ways from devices with variable focal lengths BUT there IS some crossover where, for simplicity, it makes sense to call that one specific length in a cell phone an optical zoom.
