Yes it gets a little better at 8 megapixel and even just another notch better at 12 megapixel, but I doubt you will see this on a regular base.
So why do some people think that 50 megapixels for the next FF camera is a great idea?
Funny reasoning. Print larger than 30x30 cm and boom you need more pixels. Start cropping, ....
Also the calculation for 30x30 cm is not as easy. A 5 MP camera does not record 5 MP in red, green and blue channel. Recoding fine detail at 50 MP and compressing the data to a 5 MP image will yield more information than starting out with 5 MP image in the beginning. Not everyone needs 50 MP or 80 MP, but some people do and some people just want it because they can. No reason for a discussion.
Why does Pentax introduce a 36 MP camera, why not start out with 12 MP. You have to find out for yourself, everything else i spointless reasoning.
