Lot of Megapixels, Lot of problems

 That's basically the Conclusion of this article recently published by FStoppers. 

The camera industry thrives on spectacle. Every new launch has to sound revolutionary, and the easiest way to do that is with bigger numbers and shinier promises. But in practice, many of those hyped specs do little to improve photography, and some make it worse. Professionals know that what matters isn’t the number on the brochure. It’s the reliability of the tool in the field. At the end of the day, cameras should serve the photographer, not impress shareholders. 

I used to shoot with a Sony camera that delivered 46 MP, and I experienced many of the problems described in this article. Now I’m shooting with a Canon R6, a 24 MP camera — and it works perfectly for me.
