Depth-of'field preview
Your camera is equipped to help you preview just what will and
what will not be sharp in your pictures. By depressing the preview
lever near the lens mount, you can close the lens down to whatever
aperture you have set. You can then preview how much sharpness
you will get in your picture by examining the picture area on the
ground glass. After previewing your picture, if you release the
preview lever, the lens will return to full aperture for focusing.
You cannot, however, preview the depth of field with your camera
set in the Programmed AE mode.
Note: Taking pictures
in incorrectly exposed
with the preview lever depressed will
pictures.
