9. Depth of field
• Approximate depth of field can
be determined by checking the
depth of field scale.
• Using the aperture stop-down
button of the lens or the camera's
depth-of-field preview (stop-
down) button (with the D4,
D3-Series, D800-Series, D700,
D300-Series, D90 or D7000
camera), the depth of field can be
observed while looking through
the camera viewfinder.
• For more information, see p. 258.
Note: When the lens is tilted, neither the depth of field
scale nor the distance scale can be used. (Both scales
can be used when the lens is shifted only.)
10. Focusing at a predetermined
reproduction ratio
The reproduction ratio is the relation between the size of
the image recorded on film and the actual subject size. If,
for example, the image on the focusing screen is one-fifth
the actual subject size, the reproduction ratio is 1:5.
To obtain the appropriate reproduction ratio for each
focused distance, see the table on page 258.
