ATTACHINGTHE PHOTOMICFINDER To attach the finder to the camera with the lens in place, first set the lens aperture diaphragmat t15.6 or larger and place the finder in position loosely.Make sure that the meter cbupling pin is in the center. Then pressdown gently on the finder until it clicks into place and the two clampssettle into place. Mounting the finder on the camera body without a lens is simple. Just set it in position and press until it clicks into p lace. To remove the finder, first, depressthe baseof the finder re- leaselever and then turn the lever downward. Next, pressthe finder releasebutton on the back of the camera. www.orphancameras.comView original page 7

The finder will come loose and can be lifted out. ShutterSpeedCoupling When the Photomic finder is attached to the camera, the shutter speed dial on top of the camerais inaccessible.There- fore, an auxiliaryshutter speedscaleis providedon the finder. With the finder in place, twist the shutter speed selector back and forth until it engagesthe dial on the camera and the two rotate together.View original page 8

phragm feature of Nikkor lensesto measurelight with the
lens wide open. Full-aperturemetering gives a bright, clear
finder image for viewing and focusing and minimizes the
effect of light enteringthe viewfinderfrom the rear.
ln order to measure exposure at full aperture with lenses
having different maximum apertures, the meter must be
adjusted to the maximum aperture of the lens in use. This
is done each time the lens is attached or changedasfollows:

The exposure meter in the Photomicfinder must be adjusted
for the film speed (ASA number) of the film in use. Lift up
the milled ring around the film-speeddial and turn it so that
the film speedappearsoppositethe red arrow. The film speed
dial covers a range from ASA 6 to 6400 with two dots
between each pair of numerical settings for intermediate
valuessuch as ASA 64, 80,125, etc.

INSTALI-INGTHE BATTERIES Two 1.5V silver batteriesare suppried with each photomic finder. They must be installedin the battery chamberon the < Nikon F2 camera basepratebefore the meter circuit wirl operate. To install the batteries,twist the baseplatecap with a coin or similar object to remove it and drop the batteries into the chamber.Make sure that the nlus (+) side facesout. caution: Remove the sirverbatteriesfrom the camera when not in usefor a long time. At below-freezingtemperatures,the batteriesmay malfunc_ tion or ceaseto operate until the temperaturerisesagain.Be careful not to expose the battery to severe cold for long periodsof time.View original page 12

Checkingthe Batteries
A built-in battery checkerlets you check the condition of the
silver batteriesat a glance.Pull out the film-advanceleverto
uncover the red dot, press the battery checker button and
watch the needle in the window on top of the finder. lf the
needle swings to the right edge of the notch or beyond, the
batteries are in good condition. lf not, they need to be re-
placed.

EXPOSUREMEASUREMENT(fuil-aperturemethod) 1 3
The exposure meter,in the Photomic finder featuresa center-
weightedthru-the-lensmeteringsystem cross-coupled with the
shutter speedand aperturecontrols.The meter readsthe light
over the entire focusing screenbut favorsa central area.This
meansthatcorrect exposuresare easy to get even in situations
where an averagedreading would result in wrong exposure.

The film-advance le,veralso servesas an on-off switch for the
exposuremeter. To turn the meter on, pull out the leverjust
farenoughto uncoverthe red dot on top of the camera.When
the meter is not in use, pressthe lever f lush against the camera
body to avoid drainingthe batteries.

The amount of light reachingthe film is determined by a
combination of lens aperture and shutter speed.Since the
two are interrelated,different combinations will give the
sameamount of exposure.The "best" combination depends
on the results desired. Use fast shutter speeds to freeze
motion or slow ones to createdeliberateblur. Small apertures
give greaterdepth of field; largeones let the subject stand out
against an out-of-focusbackground.
To determine correct exposure, adiust the aperture andlor
shutter speed until the meter needle is centered in the U-
shaped notch visible in the viewfinder (+ and - marks let you
know whether you are over- or underexposing)or at the
U-shapednotch located beneath the window on top of the
Photomic finder. For fine adiustments of less than one
f lnumber, either the aperture ring or the shutter speed
(except for speedsslower than 1/80 sec.) permits reliablein-
termediate settihgs.

't6 EXPOSUR E M EASUREMENT-continued
Under extremely low light conditions, the meter needle may
center at the "B" setting on the shutter speed selector' lf so,
correct exposure time is 2 seconds.
lf the needle moves erratically or cannot be centered even
after all possible aperture-shutterspeed combinations have
been tried, then the light is too bright or dim for the meter's
range. Effective range (coupling range) variesaccording to the
leni and film speed used. For example,with the 50mm f/1'4
lens and a film speed of ASA 100, it extendsfrom f 11,4at 1
second to f l8 at 1 12000 second.
For added conveniencewhen measuringexposures,the actual
shutter speed and the aperture selectedappear in the bottom
edge of the finder viewfield. This permits exposure setting
while observingthe exposureneedlein the viewfinder'

Gettingthe Right Exposure
The central part of the focusing screen should always be
aimed at the main subject when centeringthe needle.Other-
wise unimportant bright or dark areas may have adversein-
fluence on the exposure reading. lf an off-center composition
is desired,f irst measurethe light striking the main subject and
set the aperture and shutter speed to centef the needle.Then
move the camera until the desiredcomposition appearsin the
viewfinder.
For subjects of uniform brightness,a reading may be taken
from any part of the subject. However, if the lighting is harsh
or contrasty, move up close and measurethe light falling on
the most important part of the subject in which deall is
desiredin the final picture.
lf the picture includes an unusually bright source of light
such as a light bulb or expanse of sky, move the camera so
that the light source does not dominate the viewfinder while
you make your reading. For backlightedsubjects,move up.
close and include dark areas of the subject in your reading.

Keepout stray light!
The finder is designedto minimize the effect of light entering
through the finder eyepieceunder normal conditions. How-
ever, in the following situations,theuse of a finder eyecup is
recommended to insure complete exclusion of stray light:
o When the camera is in sunlight and the subject is in

EXPOSURE MEASUREMENT:SPECIALCASE Stop-DownExposureMeasurement With the following lenses and accessories,full-aperture ex- posure measurementis not possible,either becausethe lens has no auto-diaphragm or because the diaphragm will not couple with the meter. Therefore, the stop-down method must be used. This means measuringexposurewith the lens apertur€ diaphragm stopped down to the taking aperture. First, push the coupling pin up into the Photomic finder with a coin or similar object so that the f15.6 appears in the maximum apertureindicator window. Mount the lensor lens/ accessorysetup on the camera and switch on the meter in the usual way. www.orphancameras.comView original page 21

To deterrnineexposure, select the desired shutter speed and
stop down the lens manually until the needlecenters.
PresetLenses
Use the same procedure as above for lenses having preset
diaphragms,such as the PC-Nikkor35mm f 12.8.
Auto LensesWithout CouplingProng
Some lenseslike the Zoom-Nikkor Auto 200-600mm f/9.5
have an auto diaphragm but no coupling prong. Use the
depth-of-field preview button to stop down the lens until the
needleis centered.

Note: Since focusing may be difficult or impossibleat small
aperturesdue to image darkening on the screen, first open
the lens to fullaperture to focus. Then determinethe correct

ExposureCorrectionfor SpecialLens-Focusing
ScreenCombinations
Becausethe light-transnritting properties of some focusing
screens differ from those of ordinary screens,certain lens-
screen combinations require exposure correction to com-
pensatefor the influenceof the screen.The numbers in the
table on the opposite page show the exposure corrections in
f-stops. With the Photomic finder, the method used is to
set the film speed (ASA) against the proper compensating
mark engravedon the film speed index ring. For example, the
table indicates a half-stop decrease(-1 12) for the Fisheye-
Nikkor Auto 8mm f/2.8 lens with type C screen.lf thefilm
speed is ASA 100, lift up the index ring and set the number
100 on the film speed dial opposite the -1 12 mark.
When no exposurecorrection (0) is indicated,the ASA rating
for the film in use should be opposite the red arrow.
