When you hove finished toking pictures, the lever should be pushed gently

UNTOADING THE CAMERA
When the end of the film is reoched, o sudden difficulty will be felt in the
winding of the film odvonce lever. At this position, no further odvonce should

To rewind the film, turn the A-R ring on the shutter releose button to the "R"
(rewind) position, lift up the ropid rewind cronk (Fig.20) from its position on
the rewind knob ond turn it in the direciion of the orrow.
As the film is being rewound, o slight resistonce will be felt, ond the red dot

i EXPOSUR,EDETERMINATION
For determining the exposure in the Nikon F Photomic-T comero, either of the following methods is

lenses,use this method. No considerotionos to the preselectedoperture is required,to toke futl
odvontoge of viewing the brightestfinder imoge for both focusing ond composing.
! Stop-down meqsurtng method
lf the lens is not equipped with o meter coupling prong or the prong connot be coupled for
ony reoson, determinethe exposure by stopping down the diophrogm to the toking operture.
In elther cose, proceed os follows:
l. Set the mqx. operture of the lens being used to the film speed
(ASA).
2. Depress the switch-on button of the exposure meter. lFig. zal
3. Viewing the finder eyepiece, focus ond compose the picture.
4. Turn the shutter speed ond/or the operture ring, until the meter

The meter is outomoticolly switched on when the side button on fhe Photomic-T Finder is depressed, by
which the top button ot the some iime pops up so thot o red line oround the top button comes in sight.
The meter needle is visible on ihe top of the finder os well os ot the edge of the finder viewfield. Turn

IMPORTAT{T!
I When the Meter is not used, depress the top button (Fig. 281 until the red line
disoppeors ond the side button pops up, to qvoid unnecessory droin of the mercury
bottery. The red line will serve lo orouse your oitention.
Since the exposure meter in the Photomic-T Finder meosures the light octuolly possing
lhe comero lens, there is no need when using o filter to colculote the filter foctor. For
lhe some reoson, no compensotion of the exposure set by the needle centering is needed,
such os required when the lens-to-comero distonce is extended for close-ups by using
on extension ring or bellows focusing qttochment. lt is only importont to observe lhe
procedure : focus ond then set the exposure. Of course, no picture should be token
with the filter removed, ofler the exposure is set with the filter ottoched.
SOME COMPENSATIONS NEEDED
The meter meosures the overoge brightness of the scene covered by the lens. Consequenily, for speciol
lighting conditions os betow, the meter might give settings which moy result in either under- or over'exPosure'
Depending upon the conditions, some compensotion for this possibility moy be necessory.

Point the comero, only while meosuring the exposure, toword o tower position or opprooch the subiect os
