Iphone camera lenses question

copied from earlier post that I believe was wrong forum

Does anyone know the real answer to just what the FF equivalent focal lengths and digital zoom capabilities are for iphone 13 pro and pro max.

From published material the ultra wide lens is a fixed 13mm equivalent, the wide lens is a fixed 26 mm equivalent and the telephoto is a fixed 77mm equivalent, This seems to be very straight forward and understandable for someone that is knowledgeable in photography (cameras) terms.

But what resulting effective focal length equivalent is achieved at maximum digital zoom with each of the three fixed focal length lenses?

But there seems to be no data published that specifies just how the digital zoom range affects the total effective final focal lengths for each fixed lens or total effective focal length.

This question is complicated by the fact that published specs state that these cameras have optical zoom also, which is wrong or at least deceptive when based on standard terminology for camera lenses.

Thanks in advance.
