Please note that I specifically said “equivalent focal length”.

A 24mm equivalent will have almost the exact same perspective on any sized sensor, because that’s what equivalent means. It’s a relationship of sensor size to actual focal length.

A 16mm on a 1.5x APs-c is a 24mm equivalent on a 35mm. The iPhones base lens is something like 1.5mm but when related to its sensor, it’s roughly a 24mm equivalent.

There’s no cropping that needs to happen.
