FOCUSING
Focusing isdone at full aperture with Nikkor lenses fisted with
an automatic diaphragm. This technique provides the bright-
est possible images on the focusing screen for easy focusing
and composing. It also minimizes depth of field so that the
image snaps in and out of focus distinctly.
The Nikon Type K screen comes with the camera as standard
equipment. To focus, turn the focusing ring on the lens until
the two halves of the rangefinder image coincide to form a
single, crisp image; when using the microprism ring, turn un-
til the microprism pattern shifts to a sharp and crisp image.
You can also focus on the matte field that surrounds the
rangefinder/microprism central area.
The lens can also be prefocused using the distance scale en-
graved in both meters and feet on the lens barrel. Simply turn
the focusing ring until the desired camera-tosubject distance
(as measured or estimated) is lined up with the distance scale
index on the lens barrel. This technique is useful for candid
shots of elusive subjects when time does not permit through-
the-lens focusing.
