The traditional digital camera market is running around 20m units a year, down from 120m ten years ago or so. Apple sold over 200m cameras with integral phones last year, and they have perhaps 15% of the market. So I submit that this ship has sailed. Apple, Samsung and Huawei are the biggest camera makers in the world, and the biggest the world has ever known.
Last week my daughter (whose Nikon DLSR is gathering dust) posted images of her three girls on their first day of school taken with her iPhone X, using portrait mode, that were both technically and artistically excellent. Great color, great bokeh with suitably shallow (but not too shallow) DoF. Sharp and crystal clear, at least when viewed as intended, on a screen. I doubt she did any editing; perhaps she straightened them, but I don’t think even that happened.
I also posted some pictures of the girls I took over the weekend with my ILC, carefully processed in LR. Also excellent (IMHO). But definitely no better than hers.
Are there images I can get with my kit that she can’t with her phone? Sure.
Do I enjoy shooting with my kit more than with a phone? Sure.
But none of that matters. Apple et al are the leading camera makers today. Canon, Nikon, Sony and the others are rapidly becoming (or already are) niche players in a declining niche.
