FOREWORD
The Micro-Nikkor 105mm f / 4 is a special telephoto lens designed for
close-up photography at high reproduction ratios. It features the same
optical construction as the much-acclaimed Bellows-Nikkor 105mm
f / 4 , but with a special focusing helicoid that enables operation f r o m
infinity (°°) to a reproduction ratio of 1 : 2 (half life-size) w i t h o u t the
need for any adapters. The lens offers "automatic maximum aperture
indexing" (Al) with suitably equipped cameras, via the meter coupling ridge provided. The ridge and the auto diaphragm function together to permit full aperture exposure measurement; the lens is also
fitted with a meter coupling shoe to permit the same operation with
Nikon cameras which lack the Al facility. In terms of optical performance, the Micro-Nikkor's excellent flatness o f field is a stand-out
feature, enabling virtually distortion-free images at all reproduction
ratios. The application o f Nikon Integrated Coating (NIC) further enhances performance by increasing image contrast, while reducing flare
and ghost, for outstanding color reproduction.
When the Micro-Nikkor 1 05mm is used with the special A u t o Extension
Ring PN-11 or PN-1, focusing is further extended from 1 : 2 to 1 : 1 for
full life-size reproduction.
To get the best results from your Micro-Nikkor 105mm f / 4 , read this
instruction manual carefully. Keep the manual handy for reference
until you have thoroughly familiarized yourself with the lens and its
operation. A few minutes of preparation will help you avoid costly
mistakes.
MOUNTING THE LENS
Position the lens in the camera's bayonet
mount, aligning the mounting indexes on the
camera and the lens. Twist the lens counterclockwise until it clicks into place.
To remove, depress the lens release button on
the camera and twist the lens clockwise.
Note: When mounting the lens on a camera with a
meter coupling lever (Al type), make sure that the
camera's meter coupling lever is correctly positioned;
when mounting on a camera without this lever (nonA l type), conventional " m a n u a l " maximum aperture
indexing is required. In both cases, refer to the
camera's instruction manual.
FOCUSING
The fully automatic diaphragm o f the MicroNikkor enables focusing with maximum image
brightness throughout the entire focusing range
o f the lens. As the image is constantly viewed
at the maximum aperture setting (i.e., f / 4 ) ,
the depth of field is minimized so that the
image snaps in and out of focus rapidly and
distinctly.
To focus, turn the focusing ring until the image
on the focusing screen appears sharp and crisp.
Via the special focusing helicoid, the MicroNikkor operates continuously f r o m infinity
(°°) to 0.47m (1.55 ft) for a reproduction
ratio of 1:2.
The distance scale on the focusing ring is
marked in both meters (white) and feet (yellow). These figures indicate the distance from
the subject to the camera's film plane.
Note: The exact position of the film plane is indicated on all cameras for convenience when measuring.
On Nikon F/F2 cameras, the top edge of the serial
number is the exact position of the plane. On
other Nikon and Nikkormat cameras, the plane is
indicated by the symbol (-Q-)
Recommended Focusing Screens
Nineteen different interchangeable focusing
screens are available for F and F2 Nikon
cameras to suit any type of lens or picturetaking situation. Those which are recommended for use with this Micro-Nikkor 105mmf/4
lens are listed below.

Reproduction Ratio
The reproduction ratio is the numerical expression of the relationship between the image size
(to be recorded on the film) and the actual size
of the subject. For example, if the image on
the focusing screen is one-fifth the actual size
of the subject, the reproduction ratio is said to
be 1:5, and is indicated on the reproduction
ratio scale of the Micro-Nikkor 105mm f/4 by
the number "5'!
•
0
© = Excellent focusing
® = Acceptable focusing
The image is brilliant from edge to edge, but the
center area (range-finder, microprism or crosshair) is dim. Focus on the surrounding matte
area.
0 = Acceptable focusing
Slight vignetting (or moire phenomenon, in the
case of the microprism) affects the screen image.
The image on the f i l m , however, shows no trace
of this.
• = Not usable
= With these lens-screen combinations the viewfinder can be used only for focusing; exposure
measurement is not possible.

Focusing at Predetermined Ratio
Above the distance scale on the focusing ring
are two reproduction ratio scales inscribed in
orange. The inner scale, with figures from 1:10
to 1:2, represents the reproduction ratios obtained when the lens is used alone. The outer
scale figures (i.e., 1:2 to 1:1) represent the
ratios possible when the lens and, PN-1 or
PN-11 ring, are used together. Using either o f
these scales, you can photograph at a predetermined ratio without calculating the
distances required. To photograph at a reproduction ratio o f 1 : 5, for example, just turn
the focusing ring until the number " 5 " is
aligned with the distance scale index; then
aim at the subject and adjust your position
(close to, or farther away f r o m , the subject)
until the image appears sharp and crisp on
the focusing screen.

NOTES ON FOCUSING
Depth of Field
Depth of field refers to the zone of acceptable
focus extending in front of and behind the
plane of sharpest focus. As this zone is exceptionally shallow at high reproduction ratios,
previewing is desirable before shooting. To
preview, press the depth-of-field button on
the camera and the lens will close to the
preselected aperture to allow you to see how
much background and foreground is in focus.
Depth of field can also be observed by reading
the color-coded indicators inscribed on the
lens barrel. The pairs of colored lines on either
side of the white distance scale index line
correspond to f/numbers of the same color on
the aperture scale. At close distances, so little
is in focus that the depth-of-field tables on
pages 13 ~ 14 are more useful.
Camera Shake: Close-up photography poses
several problems not encountered in general
photography. One of these is sensitivity to
vibration—the magnification of the image is so
high that even slight displacement during
shooting results in a blurred image. Therefore,
the use of a tripod is recommended at all
times, with shutter actuated via cable release.
In this respect, the convenient, 360° rotatable
tripod mounting collar on the PN ring will
prove useful.
Close Working Distances: At high reproduction
ratios encountered during close-up shooting,
depth of field decreases drastically. This condition can be partially compensated for by
stopping down the lens. But at very close
working distances, an extremely shallow depth
of field is inevitable. Careful placement of the
camera will be necessary to ensure that the
important surfaces of the subject are in the
same zone of sharpness.

With Built-in T T L Metering
The Micro-Nikkor has a fully automatic diaphragm with settings from f/4 to f/32. The
Micro-Nikkor couples fully to the thru-thelens meter o f any F/F2 Nikon Photomic or
other N i k o n / N i k k o r m a t cameras for full aperture exposure measurement over the entire
range of aperture settings. Note that when
this lens is used with non-AI cameras, conventional " m a n u a l " maximum aperture indexing is required.
When close-up attachments such as a PN ring
or bellows are used, the exposure measurement method is shown in the table on the left.
When the lens is mounted in the reverse position, the stop-down method should be used.
See the instruction manual supplied with your
camera or Photomic viewfinder for details.
Caution: When the stop-down method is used at
small apertures, a finder eyecup should be attached
to the eyepiece to ensure complete exclusion of
stray light.
10
Without TTL Metering
At close ranges (reproduction ratios greater
than 1:10), the amount of light reaching the
film decreases as the lens-to-film distance increases. When non-TTL measurement is used
for this range, the result is underexposed
photographs unless compensation has been
made for this decrease. (When the MicroNikkor 105mm f/4 lens is used with the Photomic or Nikon/Nikkormat TTL meter it is
not necessary to make compensations, since
the meter is designed to give an accurate
reading of the amount of light reaching the
film.)
The table at right gives the exposure factors
(compensation values) with exposure increase
in f/stops for non-TTL exposure measurement
at reproduction ratios greater than 1:10.
