Quote:What we actually see is that the 40-50mp FF sensors offer more resolution than lower res FF sensors. So will 80mp FF sensors.
What you will see is that the smaller the pixel pitch gets, the sooner you will see diffraction softening affect resolution. So, higher res. sensors make sense with bigger aperture useage.
That doesn't answer why you need more resolution. What is the use case for the average photographer?
I'd postulate that 8K (33mp) will be the end of line for TVs/screens. For posters of sane size that you'd actually mount to a wall, you don't need more anyway.
That leaves cropping ("zooming in") as a use case. True - that one is valid and we see that this is widely used on smartphones ... because you only got 1, maybe 2 primes in there. But is that a valid use case for system cameras (other than applying small adjustments) ?
Maybe habits will change - technically a 250mp camera with an ultra-wide prime lens is cool for a 20mp tele crop? We aren't quite there yet though ...
