Why does that happen? Is it because there's a physical antialiasing filter in the lens?

The 48MP sensor still has 48MP of monochromatic resolution, but it only has 12MP of effective color resolution. You'll still see fine details, but the colors are not as high resolution as the details. This is rarely a problem, given the way the human eye processes color.
- willis936 4y agoI'm not an optics expert, but I expect that the physical system's spatial bandwidth is much higher than the sensor's bandwidth. That is to say, if there were more light sensing elements I think the spatial bandwidth would be higher. I don't think the artifacts are directly from aliasing but rather an artifact of software interpolation. It anyone knows better please correct me.
- sudosysgen 4y agoThis is generally not the case here, if the lens was physically perfect it could not resolve two points closer than two pixels as per the Rayleigh criterion.
