There have been some useful discussions here about optical zoom on the iPhone 15 pro Max, but I think I have a more specific question. If you open the “wheel”, i.e. by holding your finger on one of the focus buttons, if you rotate the entire wheel is it sitting in optical all the way 0.5x until x5? I noticed if you continue above around times x8, a rectangle appears which diminishes as you increase “zoom“ which I presume this means digital zooming has started. This implies that all the way from times .5 through to x5 is all optical. But is it? Personally I am interested in the optical zoom ranges so that I can set a magnification throughout glass only.
