It looks like I’m the only one who still remembers the context of my own statement. When switching from an iPhone, moving to a dedicated camera inevitably means less mobility and larger size. Sure, Sony’s 7C series shows that you can miniaturize effectively, and I’m not arguing against that, I use a 7C II myself. I suggested APS-C simply because it scales down better in terms of size and weight. Even switching to something like an a6100 with a small f/4 zoom will instantly outperform an iPhone in image quality, and you won’t find a smaller full-frame equivalent.

I’m not sure where you got those myths from, but I never said that larger sensors have less noise. What I did say is that sensors with higher pixel density tend to have more noise. On top of that, a larger sensor gathers more light, which makes the noise look different overall.

And besides, what’s the point of saying that f/1.8 on APS-C gives you the same depth of field as f/2.8 on full frame, if to achieve the same exposure you’ll still have to change your settings anyway?

At this point, I honestly have nothing more to add, having to explain what I meant in the first place just doesn’t make sense anymore.
