I really don't agree with calling the D5300 a mid-range camera, it's 2013-2014 tech. Like I mentioned somewhere else I do understand the price comparison but it's not a mid-range camera anymore, it's very outdated.

Even with less outdated cameras (e.g. the last high-end APS-C from Nikon, the D7500), HDR bracketing is much worse than most mid-range phones from the last 5 years. And assembling them after manual bracketing in post-processing is also not great. Nikon HDR creates halos, doubling, even on relatively fast shutter speeds.

That said, I don’t have the experience of phones being "good enough", and even my Sony RX100 (edit: was "RX1", my bad) first gen which is quite old is out-performing 99% of the smartphone market in picture quality on a good screen, if you exclude HDR.

I doubt phones will ever reach the raw quality of RX1 due to physics, especially the RX1r II. That thing is still a beast.

Sorry, I meant to say "RX100", it is now corrected. Yes, even with the improvements in sensor technology, glass, and post-processing I don't see a phone reaching RX1 quality anytime soon.
