When focusing manually, set your camera to the manual focus and rotate the focusing ring while looking through the viewfinder. The focus signal in the viewfinder indicates the current condition of the focus. Depth-of-field scale When focus is set on a subject, anything at that same distance will appear sharp, and anything within a certain range before and beyond the subject will also appear in focus; this is called depth of field. Depth of field depends on the subject distance and aperture you choose and is indicated by the lines on the depth-of-field scale corresponding to the aperture. · The depth-of-field scale is for 35mm-format cameras. The depth-of-field is shallower when you use Digital Single Lens Reflex Cameras equipped with an APS-C sized image sensor.
