Reference-Manual Focus Manual Focus Controls used: Focus-mode selector ➤ Lens focus ring Manual focus is available for manual focus lenses or when autofocus does not produce the desired results. To focus manually, set the focus-mode selector to M and rotate the lens focus ring until the image displayed on the clear matte field in the viewfinder is in focus. Photographs can be taken at any time, even when the image is not in focus. A-M Selection/Autofocus with Manual Priority When using a lens that offers A-M selection, select M when focusing manually. With lenses that support M/A (autofocus with manual priority), focus can be adjusted manually with the lens set to M or M/A. See the documentation provided with your lens for details. The Electronic Range Finder If the lens has a maximum aperture of f/5.6 or faster, the viewfinder focus indicator can be used to confirm whether the subject in the selected focus area is in focus. After positioning the subject in the active focus area, press the shutter-release button halfway and rotate the lens focus ring until the in-focus indicator (●) is displayed. Focal Plane Position To determine the distance between your subject and the camera, measure from the focal plane mark on the camera body. 35
