Depth Of Field - Nikon AF-S Micro NIKKOR60mm f/2.8 G ED Manuel D'utilisation

5. Depth of field

The depth-of-field indicators
are engraved beside the
distance index line. At close
En
distances, however, so little is
in focus that it may be better to
check the depth of field table
(on page 156). If your camera
has a depth-of-field preview
button or lever, use it to check
the depth of field in the viewfinder.
6. 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 photograph at a predetermined reproduction ratio, use
the following procedure:
Manually turn the focus ring until the desired
a
reproduction ratio scale number is aligned with the
distance index line.
Aim at the subject, then change your position, moving
b
closer to or farther away from the subject, until the
image in the viewfinder sharpens.
To obtain the appropriate reproduction ratio for each
focused distance, see the table on page 156.
7. Notes on close-up photography and duplication work
Camera shake
The AF-S Micro NIKKOR 60mm f/2.8G ED provides such
exceptionally high image magnification that even the
slightest movement during shooting can cause the image
to blur. Be sure to mount the camera on a tripod and use a
cable release or remote cord to release the shutter.
