This isn't my experience _at all_. Until about six months ago, I carried a Fujifilm X-E2. It's an older camera (~2014), and was 16.3 MP. I upgraded to an X-Pro3, which is 26.1MP. Given that the MP stat increases with the square of resolution, that's not a huge change. My iPhone X has a 12MP camera, the same as the iPhone 13 Pro. The technical resolution _doesn't matter_. It hasn't mattered since the 10MP barrier was breached. I would prefer the Nikon that I carried in ~2004 to the iPhone 13 Pro for "photography". Note that that is in quotes, because "photography" is very different from "taking pictures". I use my iPhone when I'm with my family most of the time and it's great for that. It's great for documenting activities and "capturing memories". That's not at all the same thing as "photography". My X-Pro3 can produce excellent images at 12,800 ISO and f/1.4. My iPhone doesn't even tell me what ISO its capable of as far as I know, has a static f/2.4 aperture, and the OS "Camera" app doesn't even let me set shutter speed. It does "does its best". They aren't comparable tools.
Recommends it
Fujifilm Mirrorless Cameras (mine is 2nd gen XE2). First ever interchangeable camera I carry with me to all my family trips. Excellent build quality, physical controls, high quality lens options and not to mention insanely great jpegs straight out of the camera. I have taken so many wonderful pictures and captured so many precious moments of my family and kid, it is easily the best purchase I made by a long shot.
