Question about optical zoom on iPhone
Posted by: space-time

I am looking at comparison between various iPhone models. For example

SE (2nd gen), 1 camera (wide), Optical Zoom: none
iPhone 12 mini, 2 cameras (ultra wide and wide), Optical Zoom 2x
iPhone 12 Pro, 3 cameras (ultra wide, wide, telephoto), Optical Zoom 4x.

When they mention an optical zoom, are they referring to the ratio of the focal length between cameras, or each of those cameras has an optical zoom built in?

to me, zoom is a continuous change in magnification, not a jump from one fixed focal length to another.

Jump from one fixed focal length to another currently.
