The telephoto camera alone is also technically interesting in a few ways. It offers continual optical zoom across the 75-100mm range without in-sensor cropping.

This doesn’t run across the full gamut, but it does roughly cover the 3-4x optical zoom range, which is often used in portrait photography.
