how can smartphones have 108MP cameras, yet conventional cameras achieve better results with apparently less MP

Question

I get that more MP is better ends up being pure marketing. However I don’t understand why all cameras don’t bring 108 MP sensors or whatever. I’m confused.

Answer 1

The high MP count in phones is compensating for not getting a lot of light in the lens due to them prioritizing small (thin) size rather than photo quality, and would rather put multiple lenses than a zoom lens for example
