MOUNTING THE LENS The PC-Nikkor 35mm fj2.8 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.
SETTING THE APERTURE 6 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.
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 re a ding .
FOCUSING 8 The aperture and preset rings of the PC-Nikkor enable focusing at full aperture for the brightest viewfinder image, with rapid setting of the diaphragm to the pre- set shooting aperture. Having set the preset ring to the desired aperture setting, focus as follows: Turn the aperture ring to the f/2.
Depth of Field Depth of field refers to the zone of acceptab l e focus extend in g in front of and behind the plane of sharpest focus. Within this zone, image blur is negligible and everything can be considered as being in sharp focus.
SHIFT AND ROTATION MOVEMENT 10 The front part of the PC-Nikkor shifts up to 11 mm from the center in a plane parallel to the film, and the whole lens mount rotates through a full 360 0 . By combining the parallel shift with the rotation movement of the lens, an infinite variety of adjust - ments can be made.
Maximum Permissible Shift Depending on the direction of shift, however, there is a maximum permissible shift, beyond which distortion and/or vignetting may occur in the picture corners, because the film format is rectangular while image area produced by the lens is circular.
FRAMING As long as the camera is held in a position parallel to the subject when shooting, it reproduces scenes more or less as the eye see s them , with no unpleasant per - spective distortion. However, shooting from this position often produces unbalanced composition, since the camera is usually used close to ground level.
Inevitably, the camera must be tilted in order to include the top of the building and minimize the foreground (Fig. 2). But with the camera tilted , the plane of the film is no longer parallel to the .
FRAMING - continued The PC-Nikkor's shift and rotation movements enable you to create balanced composition without tilting the camera, so that the film remains parallel to the plane of the subject (Fig. 3). To photograph a tall building, hold the camera parallel to the plane of the building.
.
PANORAMAS The shift movement of the PC-Nikkor can also be used for making panoramic pictures by joining exposures. Its advan- tage over the normal lens mounted on panoramic equipment is that it enables you to maintain exactly the same film plane in both exposures so that the fin- ished photographs will match exact l y.
To take panoramic shots, place the lens in normal position, shift scale facing upward, and operate the milled shift knob to shift the lens as far to the left as possible.
PANORAMAS - continued These two exposures together cover a horizontal angle of 78° without turning the camera, 4° more than the range of a 24mm wideangle lens, and with the added advantage of larger image size. The table below gives a comparison of the angles of various wideangle lenses and the PC-Nikkor panorama range.
