When all else fails

Are you still unhappy with the sharpness of your images? Isn’t it too much you want?

A digital camera is basically not capable of providing absolute sharpness. Most photo sensors are equipped with a special anti-aliasing filter that slightly blurs the image so that any point of the original scene in all cases is perceived by more than one photodiode. This is called antialiasing (antialiasing) or smoothing and is necessary to prevent moiré-striped artifacts that can occur when photographing fabrics and other items that have a periodic, repetitive structure.
