Here and the differences in cameras of Iphone 15 Vs Iphone 16:-

1. Ultra Wide Camera: The ƒ/2.2 aperture of the iPhone 16 allows for far greater low-light camera work.

2. Macro Photography: The macro photos and videos that the iPhone 16 allows for are missing on the iPhone 15.

3. Spatial Video: Recordings of video-like 3D works are possible with the iPhone 16.

4. Camera Button: It's there for fast access but sorely missed on the iPhone 15.
