I just came back from a 25-day trip to Japan with a Nikon Z8 and the 24-200 f/4 lens, as well as an iPhone 15. The first half of the trip was an organized tour with twenty-two people. I was one of two people with a "real camera", the other person had a Sony point-and shoot. I found that there were many situations where I used my phone, rather than the Nikon, either because I didn't have the Nikon with me, or because it was just faster rand more convenient to use the phone. That being said, I did take a lot more pictures with the Nikon in situations where I could take my time composing or for some reason, I wanted the superior quality that I got from the Nikon. By the end of the trip, I was convinced that as much as I love my Z8, in future, I will not be using it on trips. It is heavy to carry (that didn't bother me at all twenty years ago!) and not nearly as convenient to use as a smaller device would be. I haven't yet done detailed quality comparisons of the images from the two devices, but I am tending to leave the Nikon at home on trips. From now on, it will likely be reserved for local wildlife and landscape photography. For trips, I will use my 12-year old Canon S100 and if it fails to rise to the occasion, I will purchase an equivalent, updated point-and-shoot for travel. YMMV.
A experience i have very often and hear so much of, the phone fits in your pocket, its instant access, can export images even edited so easily in Snap Seed on the phone, i have PS and LR on my phone a friend loaded but never really use it, just Snap Seed mostly.
Apple has in my opinion the best natural accurate colours and white balance, i think HE image feature in the Z8 Z9 etc is designed or made by Apple ?.
Samsung is awesome and has amazing zoom, its a brilliant phone camera, i just prefer the look of Apple colour.
Some people i know use the Apple 15 Pro Max in quality drone applications, how i don't know.
You can shoot RAW or JPEG in these phones instant panorama which i use a lot, if was holidaying over seas, i would never take conventional gear, just a good phone.
I find Phones are excellent especially for macro or very close up work.
If i am going on a dedicated photography trip that's different.
From some of the pro photographers i have heard they like the stills from phones but they love the video capability.
I like most people just love taking photos on our quality smart phones.
I din a trip not long ago, camera gear in the VAN, i took 4000 images of many weeks, all on my Canon G10 yes the old G 10 in RAW, and the rest on my phone, the DSLR gear never saw the light of day.
Only an opinion
