Last fall Canon showed off a prototype of their 250 megapixel sensor 😲. It's experimental, who knows if it ever it gets to market.
But even 120 megapixels, really? Who needs it and why? I have to admit, my Nikon D850 has 45 megapixels that I thought I'd never need, but I use them to zoom into objects when my lens couldn't zoom far enough.
Anyway, this video from Canon is amazing. Is this the future of security cams? They'll be able to tell you had braces on your teeth?
