Getting the correct exposure is about balancing aperture, shutter speed and ISO, but the f/stop used and where you focus in the frame are pivotal to the look of a photograph.single or small AF zone is better for offering precise control of where the camera focuses. In this picture, taken with a 24-105mm lens at 100mm on a Canon EOS R5, the AF point was aimed at three different points and shots were taken at a range of f/stops. The images below show the camera’s rear screen previews that indicate each autofocus point position.
