L-----------------------------------------~ 5
Insta ll ing the Batteries
Checking the Batteries
The exposure meter in the Photomic finder is powered
by two high-performance silver-oxide batteries mounted
in the battery chamber in the baseplate of the camera.
To install the batteries, first remove the battery chamber
cover (turn it 90° counterclockwise using a coin or similar object); then, place two 1.5V silver-ox ide (buttoncell type) batteries in the chamber, making sure that the
plus (+) side of each unit faces out. After inserting and
properly seating the batteries, replace the cover and lock
it to secure the assembly.
The camera's film-advance lever serves as the ON-OFF
switch for the Photomic finder. Thus, to check battery
power, perform the following: Pullout the lever just far
enough to uncover the red meter ON index on the top of
the camera; then, look within the finder to see if any of
the LEO exposure indicators are illuminated. If any of
the ind icators are lit, battery power is sufficient for
proper operation. If none of the LEOs light, battery
positioning should be checked; then, if none of the
LEOs light, replace batteries.
Note: Remove the batteries when the camera is not to be used
for a long period; this will prevent leakage within the camera.
Also, keep the camera as warm as possible when operating under
cold-weather conditions; otherwise. the batteries may fail to
function. (See "Tips on Camera Care" on page 36 for additional

triangle is aligned with the ASA value for the film in use.
The meter is sensitive across the fu II range of from ASA
12 to ASA 6400. The film-speed dial has two dots between each pair of numbers for intermediate settings
such as 64, 80, 125, etc.
Setting the Shutter Speed
The Nikon F2S8 Ph otom ic camera can be set to the de~ired shutter speed either before or after the shutter is
wound. Speeds of from 1 second to 1/2000 second are
set via the sh utter-speed selector f itted on the finder; the
se lector is a lso provided with a "8" setting for longer
time exposures. To set the shutter speed, turn the selector until the desired speed is a ligned with the white dot;
when a ligned with setti ngs of from 2 to 2000, the actua l
shutter speed will be a fractiona l value of from 1/2 second to 1/2000 seco nd . The red line provided between
the 1 /60 sec. and 1/125 sec. setti ngs ind icates 1/80
seco nd - the fastest shutter speed providing X synchronization for use with electronic flash units. When more
precise settings are required, intermediate shutter speeds
of fro m 1/80 sec . to 1/2000 sec. are usable. At the "8"
setting, the shutter speed remains open as long as the
shutter-release button is depressed. (See "Flash Synchronization" on page 34 for additional information on flash
Setting the Aperture
The ring fitted at the base of the lens adjusts the size of
the aperture (or opening) in the iris diaphragm. To preset the lens aperture, turn the aperture ring until the desired f/number setting on the scale is a ligned with the
ind ex mark provided on the lens. The iris diaphragm can
a lso be set to intermediate apertures between the clickstop settings for more precise ex posures.
Film-Advance Lever
Frame Counter
The film-advance lever simu ltaneously advances the film,
cocks the shutter and operates the frame counter. It
also switches on the exposure meter in the Photomic
finder. To advance the film, stroke the lever with the
right thumb in a single stroke (or series of strokes) totaling only 120°. A built-in locking device prevents the
shutter from being released unless it is fully cocked and
the film advanced a full frame. At the completion of
film advance, release the lever and it will return to the
20° standoff position ready for shutter release.
The frame counter operates automatically to show how
many frames have been exposed. When the camera back
is opened for loading, the cou nter is reset to the "5"
(start) position, two frames before "0". Once the
camera is loaded and the back closed, each film-advance/
shutter-release sequence will cause the frame counter to
advance one position until the maximum 20 or 36
frames have been exposed. The dial of the frame counter
is calibrated with dots (for odd numbers) and figures
(for even numbers), and with settings of "5," "12,"
"20" and "36" in red.
Note : Do not apply pressure to the film-advance lever while
making an exposure .
T-L Fingerguard
The shutter-release button of the Nikon F2SB Photomic
camera is fitted with a fingerguard that also doubles as
the shutter operation mode selector. Set to the middle
position, the fingerguard provides for normal shu tter
release via the shutter button. To lock the shutter to prevent accidental release, lift up and turn the fingerguard
until the index dot aligns with the "L" (lock) marking.
For time exposures preset via the camera's built-in selftimer, lift up and turn the fingerguard until the index
dot aligns with the "T" (time) marking. (See "Time Exposures" on page 25 for details.)
The built-in self-timer can be used to trip the shutter
after a delay of from 2 to 10 seconds. The numbers
marked on the timer scale indicate the delay in seconds.
To take a picture using the self-timer to fire the camera,
first set the aperture and shutter-speed controls, advance
the film, and cock the self-timer by turning its lever
downward until the index line (on the lever) aligns with
the figure (on the scale) corresponding to the desired
number of seconds delay; then, simply press the small
button just above the timer to start the countdown,
with shutter release occurring at the completion of the
cycle. Note that the self-timer can be set either before or
after advancing film; also, if you decide not to use the
self-timer after setting it, simply use the shutter button
in the normal way to make the next exposure and to
release the self-timer for resetting to the off position.
The self-timer may not be used at the "B" shu tter-speed
dial setting.

Camera shake is one of the most common causes of unsharp pictures, especially at slow shutter speeds. Learn
to hold the camera correctly and practice steady shutter
squeezing. The photos show the best ways to hold the
camera for sharp pictures.
Wrap the fingers of the right hand around the camera
body so that the index finger rests comfortably on the
shutter-release button and the thumb fits between the
camera body and the fi lm-advance lever. Position the
camera so that the eye looks through the center of the
viewfinder. Cradle the camera in the left hand for additional support, with the left thumb and index finger
grasping the focusing ring. From this basic stance, the
camera can be properly supported and easily switched
from horizontal to vertical format shooting. As a general
rule, the lowest shutter speed you should use with the
camera hand-held is equal to the reciprocal of the focal
length of the lens in use (e.g., for a 500mm lens, use
1/500 sec.; for a 105mm lens, use 1/125 sec.) . However,
as the ability to hold the camera steady may vary with
each individual, we recommend that you experiment. In
general, the higher the selected shutter speed, the sharper
the picture.
For sharp pictures, correct shutler releasing is just as important as steady camera ho lding. After adva ncing the
fi lm to a fresh frame, the camera is set for shutter re lease
via the button provided at the upper right. When taking
the picture, hold the camera steady (as explained previously), re lax and depress the button using a steady
even pressure to re lease the camera's shu tter- re member,
a qu ick jab of t he finger will ca use camera movement
a nd may result in a blurred ph ot ograph.
Operation via Cable Release
The shutter-release button can also be operated via a
cable release or similar accessory attached via the thread ed mount provided . With the cable release , operation is
more vibration-free and often leads to sharper images
under critical shooting situations such as photomicrography, time exposure, etc. To attach th e cable release
(Nikon-mount models AR-2, etc.) to the camera, screw
the threaded cab Ie connector onto the mount provided
around the button. Th e shutter is then tripped by d epressing the release plunger.
Focusing isdone at full aperture with Nikkor lenses fitted
with an automatic diaphragm . This technique provides
the brightest possib Ie images on the focusing screen for
easy focusing and composing. It also minimi zes depth of
field so that the image snaps in and ou t 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 until the microprism pattern shifts
to a sharp and crisp image. You can also focus on the
matte fie ld that surrounds the rangefinder/microprism
centra l area.
The lens can also be prefocused using the distance scale
engraved 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-Iens focusing.

FOCUSIN G-continued
I nfrared Photography
The plane of sharpest focus for infrared light is slightly
more distant than its counterpart for visible light as seen
through the camera's viewfinder. Thus, for sharpest
focus in infrared photography, adjustments must be
To compensate for this shift in focus, first focus the image sharp ly through the viewfinder. Then, turn the focusing ring counterclockw ise until the point focused is
aligned with the red dot (or line) provided on the lens
barrel. For example, in the picture below, the lens has
been focused for infinity (00) infrared shooting. Note
that when lenses having a focal length of 50mm or less
are used stopped down to f/8 or below, no adjustment is
necessary due to the large depth of field avai lable.
Note : Some new optics using Nikon's Extra-low Dispersion
(ED) glass, as well as reflex (catadioptric) lenses , do not require
refocusing for infrared photography. Refer to individu al len s
instruction manuals for details.
Film-Plane Indicator
Under various precision shooting situations, such as
close-up photography, it is often necessary to measure
the film-to-subject distance to ensure the sharpest focus .
Th e camera's film plane is indicated by the top edge of
the figures making up the serial number at the upper
left of the camera body. Note that these figures are
46.5mm from the front surface of the camera's lens
mounting flange.
(mounting flange front surface)
Depth of field refers to the zone of acceptable focus extending in front of, and behind, the plane of sharpest
focus. Within this zone, image blur is negligible and
everything may be considered as being in sharp focus.
Three factors greatly influence the depth of field : the
focal length of the lens in use, the camera-to-subject
distance, and the taking aperture. The smaller the aperture and the shorter the focal length of the lens, the
greater the depth of field. Also, the closer the subject,
the shallower the depth of field. These three factors can
operate independently or in conjunction with one another, with anyone factor capable of partially cancel ing
the effects of the other. Thus, by careful selection and
use, the photographer can exercise wide creative control
over the final picture.
Depth-of-Field Preview Button
As most Nikkor lenses are operated at full aperture for
ease of focusing, visualization of the depth of field at the
shooting aperture may be difficult. Thus, the camera's
depth-of-field preview button often can come in handy.
The depth-of-field preview button lets you check (or
"preview") the zone of sharpness at any time before (or
after) shooting. Simply by depressing the button, the
lens is stopped down to the preselected aperture to allow
you to see how much background and foreground is in
or out of focus.
DEPTH OF FIELD-continued
Depth-of-Field Indicators
Depth of field can be read directly from the distance
scale in meters or feet with the aid of the color-coded
depth-of-field indicators engraved on the lens barrel.
Each pair of colored lines on either side of the central
distance scale index line corresponds to fjnumbers of the
same color on the aperture scale. To find the depth of
field at a particu lar aperture, first focus the lens on the
su bject while looking through the viewfinder. Then check
the numbers on the distance scale to determine the zone
of focus for the aperture in use. The three photos shown
clearly depict the changing depth of field; with the
photo to the right, the field is shallow at the fj4 setting,
while the photo at the far right shows a depth of field
extending from approximately 2.7m (9 ft) to infinity

The exposure meter of the Nikon F2SB Ph otomic
camera's finder features a center-weighted TT L metering
system coupled to the shutter speed and aperture controls. Th e meter reads the light over the entire focusing
screen but favors the central 12mm-diameter area. This
allows you to make precise readings of the se lected subject area, and results in more balanced overall ex posures.
Underexposure"by more than 1 stop

Determining Exposure
The finder has three LED exposure indicators visible
within the viewfield ("+" for overexposure, " 0 " for
correct exposure, and " - " for underex posure); thus, the
metering system is capab le of providing easy-to-read exposure information in f ive steps, and even at extremely
low-Iight leve ls. Add itionaliy, the se lected shu tter speed
and lens aperture settings are visible for maximum ease
of operat io n for setting the desired exposure.
To determine the correct exposure with the Nikon F2SB:
Switch ON the meter by moving t he fi lm-adva nce lever
to the 20° standoff position; with this action, one of the
LED indicators will light, indicating overexposure, correct exposure or underexposure. If the plus (+) indicator
Iights, increase the shutter speed or decrease the aperture
until the center (0) indicator just comes on a nd the (+)
turns off; if the minus (- ) indicator is lit, decrease the
shutter speed or increase the a perture until the center indicator lights. Wh en two LEOs light simul ta neous ly (i.e.,
+ and 0, or - and 0). the exposure setti ng is within l -stop
of correct exposure; thus, be sure to adjust the aperture
setting slow ly to get o nly the correct "center" (0) exposure. Va lu es for the five sett ings of the LEO s are
described in the figure o n this page .
Exposure Control
Metering Range
The amount of light reaching the film plane is determined by a combination of the lens aperture and the
shutter speed. Since the two are interrelated, different
combinations will give the same exposure. A 1-step
change in the shutter speed, or a 1-stop change in the
aperture setting, will either halve or double the exposure.
For example, a shutter speed of 1/125 second passes
twice as much light as a setting of 1/250 second, and
only half as much light as a speed of 1/60 second; for an
aperture setting of f/11, twice as much light as f/16, and
half as much as f/8, is passed. This feature characterizes
the oJ)eration throughout the available range of shutter
speeds and aperture settings. With this in mind, it's easy
to see that if a correct exposure for a scene is 1/125 at
fill, then 1/60 at f/16 or 1/250 at f/8 will be equally
The best comb ination for your needs will depend on the
results desired. Use fast shutter speeds to freeze motion,
or use slow speeds to produce deliberate and creative
blur. Small apertures give greater depth of field, while
large apertures restrict sharp focus to the main subject.
The creative selection of both speeds and apertures will
greatly enhance your photography.
If the center "correct exposure" LED fails to illuminate,
even after all possible lens-aperture/shutter-speed combinations have been tried, then the available light is too
bright or too dim for the meter's range. To correct this
situation, several measures may be taken, as follows:
Switch to a new film (either higher or lower ASA) that
more closely matches the available light; mount a neutral
density filter on the lens to decrease the light reaching
the film plane; or use artificial lighting (i.e., an electronic
flash unit) to increase subject illumination. Remember,
too, that the lens in use can greatly influence suitability
for bright or dim shooting. For example, a 50mm f/1.4
lens (with ASA 100 film) couples from EV - 2 (f/1.4 at
8 seconds) to EV 17 (f/8 at 1/2000 second) for excel lent low-light performance; on the other hand, a 200mm
f/4 lens proves more usable at bright-light levels, coupling (with ASA 100 film) from EV 1 (f/4 at 8 seconds) to
EV 20 (f/22 at 1/2000). Thus, choose the lens carefully
to match the existing lighting conditions.
Extreme Low-Light Metering
The meter built into the Niko~ F2SB camera is capable
of metering low-light levels requiring slow shutter
speeds of up to 10 seconds. To meter at low-light levels,
perform the following: Set the lens' aperture ring to the
desired aperture setting, and the shutter-speed selector
to "B"; then, depress and hold the shutter-speed dial
lock and turn the selector until the center LED exposure
indicator (0) illuminates to indicate correct exposure.
Having set the selector, read off the number on the ex tralong exposure scale and set the camera's self-timer for
the indicated value; then, set the T-L fingerguard to "T"
and depress the shutter button to make the exposure.
When performing low-light metering, be sure to block the
entry of stray light into the viewfinder by closing the
eyepiece shutter or by continuously viewing through the
finder. (Refer to accompanying photos for details.)
Time Exposures
To make an exposure longer than 10 seconds, set the
shutter-speed selector to "B" and turn the T-L fingerguard to "T" as described in "Extreme Low-Light Metering." Advance the film and press the shutter-release
button to open the shutter. As long as the fingerguard
remains set to "T," the shutter will remain open. When
returning the fingerguard to the normal center position
to close the shutter, be careful not to move or shake the
camera, as a blurred image may result.
Eyepiece Shutter Operation
High-Contrast Lighting Situations
The camera's Photomic finder is fitted with an eyepiece
shutter for special unmanned shooting situations (e.g.,
remote control, automated shooting with motor drive
and aperture control unit) requiring protection against
the entry of stray light through the viewfinder eyepiece.
To close the shutter, simply turn the eyepiece shutter
control 60° clockwise; as the shutter closes, the internal
LEDs are deactivated and the external "correct exposure"
indicator is switched on for metering operation from
atop the finder. To set the camera for proper exposure
using the external LED indicator, simply adjust the aperture ring and/or the shutter-speed selector until the LED
just glows; once the LED comes on, the camera is set
for correct exposure.
In addition to its use for low-light metering or for unmanned photography, the eyepiece shutter comes in
handy to ensure correct exposure measurement in critical shooting situations (e.g., photomicrography) or for
protection against the entry of bright light into the viewfinder during daylight shooting.
When there are substantial brightness differences between the main subject and the background, unimportant bright spots or dark spots can adversely influence
the finder reading, and thus the final exposure. To prevent under- or overexposure of the main subject under
these shooting cond itions, some corrective action must
be taken to ensure proper exposure of the main subject.
Fortunately, the finder's center-weighted TTL metering
action simplifies adjustments, making for qu icker camera
operation and more accurate final resu Its.
To compensate for an excessively bright or dark background, target the main subject in the center of the focusing screen wh ile performing metering; th is action ensures that the main emphasis of the meter reading will
be on the chosen subject. Then, after completing aperture and shutter speed adjustments, recompose to the
desired picture composition and make the exposure
without readjusting the camera controls. For example,
when shooting landscapes, it is often advisable to aim
the camera slightly downward during exposure measurement to eliminate the effects of a bright expanse of sky;
without such compensation, the landscape may appear
underexposed in the final print. Also, for backlit subjects, it may be necessary to move closer to the subject
to ensure a proper reading.

• Metering with a bright area in the center will
cause underexposure of the main subject.
• For correct exposure, f irst measure the main subject;
then, recompose and shoot.
With some Nikkor lenses, full-aperture exposure measurement is not possible, either because the lens has no
automatic diaphragm, or because the lens does not couple with the finder's meter; with certain accessories, too,
lens/finder coupling is not possible, thus, preventing fullaperture measurement. However, the camera's Photomic
meter can still be used for exposure measurement via
the stop-down method. Before mounting the lens (or
accessory) on the camera body, push the meter coupling
pin up into the finder with a coin or similar object; when
set, the number "5.6" will appear in the finder's maximum aperture indicator. After setting the finder, mount
the lens or lens/accessory combination on the camera,
switch on the meter by moving the film-advance lever to
the standoff position, and then set the controls for correct exposure as follows:
For fixed-aperture lenses, such as Reflex-N ikkor lenses,
simply adjust the shutter-speed selector until the center
LED indicator comes on. For convenience, shutter
speeds can be set at intermediate settings in the 1/80 sec.
to 1/2000 sec. speed range for precise exposures. If the
meter indicates con tinuous overexposure, use a neutral
density filter or slower film. If continuous underexposure is indicated, suppleme"ntary lighting or a faster

Adjustments for Focusing Screens
Light transmission properties vary somewhat with focusing screen type, thus occasionally requiring exposure
correction to compensate for the combined effects of
the lens/screen combination in use. The numbers listed
in various blocks of the table on the opposite page denote the amount of correction necessary in f/stops. To
adjust the camera's finder for the indicated f/stop correction, lift and turn the ASA film-speed index ring
until the ASA value for the film in use is aligned with
the appropriate mark engraved on the ring. In the example figure shown, ASA 100 is aligned with the -Y:!
mark to provide the correction required when using the
Type C screen with the Nikon F2SB Photomic camera
and the Fisheye-Nikkor 8mm f/2.8 lens, as indicated in
the table. (When "0" is indicated in the table, no compensation is required.)

Adjustments for Film Compensation
Some exposure correction may be necessary when certain types of films are used for copying or photomicrography applications; the amount of correction requ ired,
however, will depend on the type of fi lm and the specific ap plication. The fol lowing table li sts the exposure
corrections in f/stops required for various film/shooting
requirements. Compensation is possible by adjusting the
shutter speed or the aperture by the indicated amount;
also, compensation is possible by adjusting the ASA
fi lm -speed index ring. In the exa mpl e shown, the index
ring is set so that the red mark is aligned with ASA 50;
this sett ing is the correct position to achieve a one-stop
increase in ex posure (three scale grad ua tions equ al one
sto p) as requ ired wh en performing photomicrography
(see table) using ASA 100 Panchromatic film.

Intentional multiple exposures for creative effects can be
made with the Nikon F2SB Photomic camera. To take a
mUltiple exposure, perform the following: Make the initial exposure, depress and hold the rewind button on
the camera's baseplate, and stroke the film-advance lever
to cock the shu tter for the nex t exposure on the same
frame; for each additional exposure on the frame, repeat
the same procedure. At the completion of multiple exposure operation, stroke the film-advance lever once
more to release the rewind button, cover the lens and
make one blank exposure, and then resume normal
operation. Note that during mUltiple exposure operation, the camera's shutter speed can be changed to any
setting for the desired shooting effect. Also, throughout
the multiple exposure operation, the camera's frame
counter will remain at the same setting as long as the
rewind button is held depressed while stroking the film advance lever.
The reflex mirror must be locked in the up position
when using either the Fish eye-N ikkor 6mm f/5.6 or the
OP Fisheye-Nikkor lOmm f/5.6 lenses, since their rear
clements protrude into the camera body and interFere
with mirror movement. Locking-up the mirror is a lso
necessary when shooting with a motor drive unit at its
top speed sett ing. To lock up the mirror, depress and
hold the depth-oF-field button a nd turn the mirror lockup lever downward until the white dot is aligned with
the white index line. The mirror will remain in the up
position until the lever is returned to the normal position.
The N ikon F2SB Photom ic camera is designed to synchronize with most types of flashbulbs at almost all
shutter speeds and with electronic flash at speeds to' /80

Ca nnot be used
No special adapters are necessary when using the Nikon
F2SB Photomic camera with the Flash Unit BC-7 or
with the Speedlight Unit SB-2. Both units mount directlyon the camera's accessory shoe and they require no
sync cords. For other flash units with ISO-type hot-shoe
contacts, mounting on the camera is via the Flash Unit
Coupler AS-'; again no sync cord is required, as the
AS-' provides fu II connection via the camera's hot-shoe
Caution: When the reflex mirror is locked in the up position,
the shutter will not synchronize with flashbu lbs at speeds faster
than 1/80 second.
The camera's Photomic finder has a ready-light built in
for use with N ikon Speedlight U nits. This unique feature
provides for greater ease of operation during flash photography, as the photographer need not remove his eye
from the eyepiece to check if the Speedlight unit is ready
for the next exposure; this built-in lamp lets the photographer know the condition of the flash (either "ready"
when on, or "not ready" when off) at all times even
while viewing. (For additional information, see the instruction manual supplied with the Speedlight.)
When shooting under low-light levels, the finder's shutter speed and aperture indicators (located just below the
viewfinder image) often are difficult to read. To solve
th is problem, the Photomic finder is fitted with a finder
illuminator. To operate, slide the illuminator switch at
the top of the finder toward the rear of the camera; with
this action, the shutter speed and aperture settings will
glow red.
Good camera care is primarily common-sense care. Treat your Nikon
F2SB Photomic camera as you would any other precision optical
instrument and it will provide you years of trouble-free service.
Although ruggedly constructed, your camera may be damaged by
shock, heat, water or misuse. By observing the following tips, you
will be assured of the longest possible service life.
• Fingerprints or dust on lens/prism surfaces will make viewing uncomfortable, and will generally contribute to a deterioration of
optical performance. Clean lens surfaces often using a quality lens
tissue or a soft lens brush; stubborn smudges should be wiped with
lens tissue moistened with alcohol or lens cleaner. Never clean lens
surfaces using cloth, paper towels, ordinary tissue, or any other
material that might scratch the lens surface; also, use cleaning
flu ids sparingly to prevent seepage, and resulting damage to mechanical components.
• When interchanging lenses, finders, etc., your camera is susceptible
to the entry of dust or other contaminants. It is a good idea to
clean moving body parts frequently to prevent the build-up of dust;
here, a lens brush and blower will come in very handy. When blowing out the interior of the camera, however, avoid contact with the
shutter curtains, as they are easily damaged. Also, wipe the outer
body surfaces using the silicone-impregnated cleaning cloth provided with the camera; thi? cloth will remove fingerprints, etc.
quickly and easily. (Note that the cleaning cloth should never be
used to clean the lens surfaces.)
• When exposed to sudden temperature changes or high humidity,
condensation may form on the lens surfaces. After using in these
situations, always dry the camera thoroughly (and slowly) at room
temperature and, then, store in a cool, dry location. Remember
that failure to dry out the camera may result in the growth of
fungus on lens surfaces- a condition that will render your camera
Should your camera be accidently dropped on the floor or in
water, take it to your dealer immediately for servicing. Thorough
servicing can be guaranteed only at an authorized dealer.
Always store the camera in an ever-ready case or compartment
case when not in use. And be sure that the lens cap is attached to
the lens. Do not leave film in the camera for a long period of time,
and never store the camera with the shutter or self-timer cocked.
Never lubricate any part of the camera. Lubrication should be left
to an authorized service center. Prior to a holiday trip or important shooting assignment, test your camera (including changing
batteries, if necessary) for proper operation.
Observe normal battery handling procedures for maximum performance at a ll times. Be sure to : Clean batteries periodically
(wiping with a rough cloth will remove residues that might otherwise impede performance); install batteries properly, checking for
proper polarity; remove batteries when not using the equ ipment
for an extended period; change weak batteries promptly to prevent
leakage within the camera; store unused batteries properly (in a
cool, dry location) to maximize service life; dispose of batteries
properly (do not burn); and keep out of the reach of children. For
details regarding battery performance, refer to the origina l manufacturer.
To remove the lens from the camera, press the lens release button and, holding the button depressed, twist the
lens to the right as far as it will go . The lens will come
loose and can be lifted out.
To mount a lens, position it in the camera's bayonet
mount so that the mounting index on the lens and the
camera are aligned; then, twist the lens counterclockwise
until it clicks and locks into place. While mounting the
lens, shade the camera from the sun with your body.
In order to measure exposure at fu II aperture with lenses
having different maximum apertures, the meter must be
indexed with the maximum aperture setting of the lens
in use. This must be done each time a lens is mounted, as
follows: After locking the lens in place, turn the aperture ring all the way to the minimum aperture setting,
then all the way in the opposite direction. Th is step
automatically fits the coupling pin of the Photomic
finder into the coupling prong on the lens and adjusts
the meter to the maximum aperture ofthe lens.
Maximum Aperture Indicator
As the lens' aperture ring is turned to the maximum
aperture position at the completion of lens/finder coupling and indexing, the finder displays the lens' maximum
aperture via the indicator (see figure below). For example, a lens with a maximum aperture of f/2.8 will
cause "2.8" to appear in the finder's maximum aperture
indicator when properly coupled. The scale is provided
with numbers (and dots for intermediate settings) of
from "1.2" to "5.6" as depicted.
Maximum Aperture Scale

In addition to the F2SB Photomic finder included with
the camera, six other interchangeable viewfinders are
available. To remove the F2SB Photomic finder to
mount one of the other units, press the finder release
lever inward and rotate toward the front (this action
releases the mounting clamps); then , depress the finder
release button at the rear of the camera body and lift the
finder out of the camera.
To attach a viewfinder other than a Photomic-type model,
set it in position and press down firmly until it clicks
and locks into place on the camera.
To attach a Photomic-type model (including the F2SB
Photomic finder included with the camera), first set the
aperture ring of the lens (if mounted) to the maximum
aperture setting; then, gently position the finder on the
camera and firmly press it down until it clicks and locks
into place (see Photo A) . Once in place, turn the finder's
shutter-speed selector left or right until it engages with
the camera's shutter-speed dial and the two can be
turned in tandem (see Photo B). Lastly, index the lens'
aperture ring with the finder as described in "Changing
the Lens" on page 38.
Nineteen d ifferen t types of focusing screens are avai lab le for use with the Nikon F2SB Ph otomic camera,
each designed to meet specific focusing requ irements.
The N ikon Type K screen comes with the camera as
standard equipment.
To change the focusing screen, first remove the finder as
described on the preceding page. Then, turn the camera
body upside-down and press the finder release button a
second t im e to release the screen.
To mount a screen, simp ly place it in position with the
flat side fac ing downward and the "Nikon" mark to the
front of the camera. Then, press the finder release button and the screen will drop into place.
Caution: When changing the focusing screen, be careful not to
touch the optical surfaces. When removing the screen , it is
advisable to place a clean , dry cloth over the palm of the hand
to catch the screen as it drops free of the camera.

Lens Hoods
The use of a lens hood is recommended at all times to
prevent extraneous light from striking the lens surface
and causing flare or ghost, and to protect the lens against
damage. Nikon lens hoods come in four types, depending on the lens: screw-in, snap-on, slip·in and built-in.
They are calculated precisely for each focal-length
Nikkor lens to provide maximum protection against
stray light.
To attach or remove the snap-on hood, first depress the
spring latch - which is marked with an arrow- and slide
it in the direction of the arrow. The hood will also fit
directly over a screw-in filter, so both can be used on a
lens at the same time. When not in use, the snap-on hood
can be reversed for storage on the lens, and the lens and
its hood can be stored together in the ever-ready case.
Nikon filters are made of optical glass, ground and
polished so that both surfaces are optically flat and
parallel. Nikkor lenses and Nikon filters are made for
each other. For best results, use Nikon filters on Nikkor
lenses. The filters are available in both screw-in and
series mounts, depending on the lens.
Except for the R60, no Nikon filter requires exposure
compensation when used with the Nikon F2SB Photomic. When using the R60 filter under tungsten light,
increase the exposure by one f-stop more than indicated
by the exposure meter.
Note: If you wish to leave a filter on the lens to protect the lens
against accidental damage, the use of th e L37 or L37C filter is
recommended .
Eyepiece Correction Lenses
Finder Eyecup
The nine eyepiece correction lenses are designed to
permit nearsighted and farsighted users to view and
focus without their glasses. Available in - 2, - 3, - 4, - 5,
0, +0.5, +1, +2 and +3 diopters, each representing the
combined dioptry of the lens and the finder. Simply
screw into the finder eyepiece.
The soft rubber finder eyecup screws directly onto the
finder eyepiece to prevent extraneous light from entering the viewfinder.
When using an eyepiece correction lens with a finder
eyecup, it is recommended to use the Nikkormat type
eyecup. First, fit the lens into the eyecup in advance.
Then screw the assembly onto the finder eyepiece.
