This is closer to what a real world vision of my description would look like. However as others mentioned, it’s an incredibly small category relative to everything else Apple do. Apple isn’t one for distractions.

Beats worked because it built on their iPhone and music streaming strategy rather than replacing pieces of either.

Leica Q is a really nice camera that compromises between ease of use and high quality optics. No need to bring Apple into the mix. I’ve owned many M series bodies and lenses but I still use the Q the most often.
