4. Depth of field
The depth-of-field indicators
%
are engraved beside the distance index line
&
. At close distances, however, so little is in focus that it may be better to
check the depth of field table (on page 126). If your camera has a depth of
field preview button or lever, use it to check the depth of field in the
viewfinder.
5. 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:
1
Manually turn the focus ring until the desired reproduction ratio scale
$
number is aligned with the distance index line
&
.
2
Aim at the subject, then change your position, moving 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 126.
6. Notes on close-up photography and duplication
work
Camera shake
The AF-S VR Micro-Nikkor 105mm f/2.8G IF-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.
