But my personal photo kit since 2010 has evolved from a pile of Nikon gear in a Pelican 1510 to a Lowepro shoulder bag, to a little body-and-two-lenses bag, to my current setup - which is an iPhone and a drone. And that setup covers about 98% of what I want to shoot.
Superwide? iPhone's got that. Panorama if I need wider. Stitching if I need even wider than that.
Nifty fifty? Got it. And Portrait Mode has gotten significantly better. Yay fake bokeh.
Underwater? I love that I can just stick my phone underwater and take photos. I had to carry a second Pelican case just for my old DSLR enclosure.
Telephoto? Ok so this is probably the biggest weakness. With a couple of exceptions where I got lucky, I've never been happy with the quality you get shooting through third party lenses or telescopes with a phone. But to paraphrase an old adage about how use a prime lens -- zoom with your drone!
I do agree that phone photos break down when you zoom in and pixel peep. They've got noise, artifacts, aberrations, all kinds of gross stuff. But you have to zoom to like 100% to see that, and the only person peeping pixels on my originals is me.
Edit: I also like that in questionable lighting conditions, my phone produces photos of a quality that would require multiple exposures and editing in photoshop to do with a regular camera.
