Replacing the Diopter Correction Lens

Look through the viewfinder and make sure that the focus frame (Rectangle with Circle) is in sharp focus. If it is not, turn the diopter adjustment dial in the “–” direction if you are nearsighted, in the “+” direction if you are farsighted. If this is not sufficient you may require an optional diopter correction lens. See below.

★Point the camera at a bright, plain object such as a white wall when making this adjustment.
