SHIFT AND ROTATION MOVEMENT
The front part of the PC-Nikkor shifts up to 11mm
from the center in a plane parallel to the film, and
the whole lens mount rotates through a full 360°.
By combining the parallel shift with the rotation
movement of the lens, an infinite variety of adjust
ments can be made.
To shift the lens, turn the knurled shift knob. The
knob should always be turned so that it is facing away
from the direction in which the lens is to be shifted.
The shift scale shows the degree of shift in millimeters.
When the shift scale is facing upward, the lens can be
shifted 11 mm to the right of center. In order to shift
the lens in other directions, simply rotate the whole
lens mount, stopping at one of the 12 click-stop
settings provided at 30° intervals, or choosing a
desired intermediate position. By combining these two
movements, the lens can be shifted up to 11mm from
the center in any direction.
