Who watches their photos on a 4K display and pixel-peeps that they're 20% less that its full resolution? (4K is about 8MP -- but you need to go to 2MP (square root of 8MP) to have half the visual resolution. 5-6MP to 8MP is much closer that it looks on paper, as the change is not linear (pixels cover an area, not a line).
