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

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.

First off, it’s a lie. Take the Samsung Galaxy S22 Ultra, in marketing, it takes a 108MP photo, but it ***does not have a true 108MP sensor.***

They use pixel binning to take a 108MP photo, which is, they take 4x 27MP photos in rapid succession and digitally stitch them together into a larger 108MP photo. This is not as effective as a regular photo as it means anything moving will become a blurry mess as the photo takes 4 times longer to take.

Secondly. phone cameras use tiny little lenses, which have optical compromises, whereas full on professional cameras often use lenses that cost more than the camera itself. Those huge lenses exist to give the best optical quality possible, among other features/capabilities not found on a tiny cell phone camera.
