Thanks great information. But doesn't Note9 also have 10x optical at least that's what I see and I assume it's optical or is it digital?

@gegphotojr Note 9 has 2x optical and 10x digital zoom.

Thank you. I noticed I could zoom to 10x but it doesn't indicate at what point it changes from optical to digital.
