NIKONOS II - FOCUSING

FOCUSING
Since the Nikonos II has no optical rangefinder,
camerato-subject distances are normally estimated. The
depthof-field indicator on the distance scale shows just how
much error you can tolerate and still get sharp
pictures Since the 35mm lens has considerable depth of field,
a reasonable estimate will usually result in sharp pictures.
Remember too that as the camera-to-subject distance
increases (and becomes harder to estimate), the depth of
field also increases, thus lowering the chance of error. (See
also ÒDepth of Field,Ó p. 22).
Turn the focusing knob on the right side of the lens mount until
the estimated distance appears opposite the white triangular
index mark. As long as the subject remains within the limits of
sharpness shown by the red pointers on the distance scale, it
is in sharp focus. Depth of field decreases sharply at
distances closer than 5 feet (1.5m), so it is good practice to
stop down the lens to the smallest possible aperture or else
measure the actual distance when shooting close-ups. The
closest distance at which the 35mm lens can be focused is
2.75 feet (0.8m).
