Focusing the camera in manual mode
For manual focus, look through the viewfinder and make sure that the area
inside the lens looks clear. The numbers on the lower bottom of the inside
screen should appear sharp to your eye. If they do not, adjust the diopter,
to the right of the viewfinder, until the numbers inside the lens look sharp.
This sets the optics of the camera to your eye, and may differ for other
photographers.
