FOREWORD

The PC-Nikkor 35mm f/2.8 is a retrofocus-type

perspective control (PC) lens with an optical

construction of 7 elements in 7 groups. The

image circle of this lens is wider than regular

35mm wideangle lenses providing a covering
angle of 78°; thus image quality is insured even
when the lens is shifted. The lens barrel can be
shifted up to 11mm off-axis and rotated 360°
with click-stops every 30° for complete image
control. The PC-Nikkor is ideally suited for
architectural and commercial photography,
enabling the photographer to properly frame
the subject without tilting or angling the
camera—and the photographer has the added
convenience of thru-the-lens viewing and meter
ing for greater ease of operation. It is also
possible to take panoramic shots.

If used with a Nikon camera having inter
changeable focusing screens, the Type E or E2
with its etched horizontal and vertical lines is
recommended. All aberrations have been well
corrected, especially coma and curvature of
field, so that image quality is truly outstanding.

MOUNTING THE LENS

The PC-Nikkor 35mm f/2.8 mounts on all Nikon and

Nikkormat cameras. To mount the lens, position it in
the camera’s bayonet mount so that the mounting
index dots on the lens and the camera are aligned.
Then, grasp the milled surface of the mounting ring
and twist the lens counterclockwise until it clicks and
locks into place. (See “Stop-Down Measurement” on
page 6 for metering procedures.)
To remove the lens from the camera body, press the
lens release button on the camera and, keeping the
button depressed, twist the lens clockwise.
To use the PC-Nikkor as a normal 35mm lens without
using the perspective control feature, rotate the lens
barrel so that the shift scale faces up. Then, if neces
sary, turn the milled shift knob until the distance scale
index dot is aligned with the shift scale index dot.

SETTING THE APERTURE

The PC-Nikkor is provided with a manual diaphragm
operable from f/2.8 to f/32 and a spring-loaded preset
ring to aid in setting the diaphragm quickly to the
shooting aperture; a total of eight click-stop positions,
at full-stop intervals, makes for precise placement of
the preset ring. Also, identical sets of f/numbers are
engraved on opposite sides of the front rim of the lens
to facilitate operation when the lens is used inverted.

To set the aperture, the following procedure is recom

mended: Press the preset ring toward the camera body

and turn it until the f/number setting corresponding
to the desired shooting aperture is aligned with the
ring’s index dot; then release the ring and it will spring
outward and lock in place. Note that the preset ring,
once set, limits the travel of the aperture ring so that
the diaphragm can be set easily and quickly from the
full aperture viewing position to the shooting aperture
without the need for checking the scale during stop­down operation.

Stopped-Down Measurement
The PC-Nikkor lens must be stopped down to deter
mine the exposure when used on TTL cameras.

Because the finder image progressively becomes darker

as the lens is stopped down, you should focus first

before taking a meter reading.

It is important to note that exposure measurement
must be performed before the lens is shifted; should
measurement be performed after shifting, erroneous
meter readings may occur. With automatic exposure
cameras, such as the Nikon F3, FE2 or FE use the
camera’s memory lock to retain the correct shutter
speed before shifting the lens for the final picture
composition. Since the Nikon EM doesn’t have a
memory lock, the correct exposure cannot be obtain
ed while shifting.
