Light diffracts around the aperture blades, spreading the point spread function across adjacent pixels. On a high-resolution sensor like the R5’s 45-megapixel chip, diffraction becomes measurable at around f/11 and visible at f/16. By f/22, you have traded resolution for depth of field at a poor exchange rate.
