The loss of resolution is visible in this case at f\/10 and f\/11. But there may be a bias, because the closing of the aperture is compensated by an increase in sensitivity to maintain correct exposure.<\/p>\n\n\n\n<p>So I organized a series of shots in my \u201clab\u201d \ud83d\ude09 with the drone stationary, a resolution target, and artificial lighting so that only the shutter speed and aperture varied (slides 3 to 5). The image at f\/4 is taken as a reference for resolution.<\/p>\n\n\n\n<p class=\"has-pale-cyan-blue-background-color has-background\"><strong>My conclusions to keep the best resolution ?<br>Aperture
