Focusing Underwater - Nikon NIKONOS-V Instruction Manual

Focusing
The distance scales on the interchangeable lenses
for the Nikonos-V are correct for on-land use. When
using these lenses underwater, therefore, you mtlst
set the distance scale to 3/4 of the actual or measured
camera-to-subject distance. For example, if the actual
or measured camera-to-subject dis tance is 1.33 m
(4.3ft), the distance scale should be set at 1 m (3.3ft).
If you estimate the distance underwater, though, you
won't have any problems; the water has the same
magnifying effect on the IE
IS
as it does on your eyes.
So just set the lens at the estimated distance.

Wait for the subject to move to the prefocused distance_
When shooting underwater, you will probably find it
more convenient to keep the lens set at a specific
distance and reposition yourself at that distance from
the subject than to set the distance for each subject.
When taking photos of fish, set the lens to a specific
distance and then release the shutter when the fish
swims to that distance.
For best results underwater, shoot with a wide-angle
lens; its deeper depth of field will let you take sharper
photos.
