Whalethe MV 1 is designedalmost totally for use on AUTO, two
other settangsare provided on the exposuremode dial for special
shooting situations.
"10OX"l This manual shutter speedsetting really need not be used
at all if you use the Pentax AF 2005 Auto Flashand keep spare
batterieson hand. lt is provided for manual flash synchronization
with flash units other than the AF 2005 (seepage21). tn addition,
it may also be used in emergencieswhen batteriesfail and you do
not have spare batterieson hand. For emergencyexposureswithout
batteries,merely set the exposuremode dial to "100X" and select
the apertureaccordingto the brightnessof your subject (refer tor
the exposureguidelinesaccompanyingthe film). The 100X setting is
also convenientfor f ilm wind on (Page10).

"8"  (Bulb): This settingis usedwhen desiringto make "Time"
exposureslongerthan 1 second.To use,first mount the cameraon
a tripod, then, attach a cable releaseto the camera'sshutter release
button. The shutter will open when the plunger of the cable release
is depressedand remain open as long as pressureis maintained. For
ultra long exposuressuch as severalminutes or hours, use a cable
releasewith a locking device.Also, cover the viewf inder eyepiece
with-the accessoryeyepiececover to prevent excesslight f rom
enteringthrough the rear of the camera.

www.orphancameras.com      FLASH PHOTOGRAPHY WITH THE AF 2OOS AUTO



To accompany its unprecedently easy auto exposure system, the
MV 1 featuresautomatic flash synch with the AF 2005 Auto Flash.
When this dedicatedf lash unit is used,flash photography is as
simple as normal exposureon Auto. Moreover,the AF 20OScouples
with a special"X" LED indicator insidethe viewfinder that enables
you to know when it is ready to fire, without even taking your eye
from the viewfinder.To mount the AF 2005, simply slidethe flash-
shoe mount all the way into the camera'shotshoeand tighten the
thumb screw.The camera'sexposuremode dial may be kept at
AUTO becausethe MV 1 synchronizesautomaticallyat 11100sec.
when the unit chargesvia a specialauto flash synch contact inside
the hotshoe.
After mounting the AF 2005, set the auto flash mode and lens
apertureaccordingto the instructionsaccompanyingthe unit.

SHOOTINGwww.orphancameras.comPOINTERS



The basic instructionsfor shooting on auto are all you need to know
to obtain successfulresultsfor most all noncritical photography.
However, the MV 1 is a sophisticatedsingle-lens-reflex camera and,
as such, is capableof a wide variety of techniqueswhich enableyou
to obtain better resultsin diff icult lighting situations,produce
specialfocusingeffects,stop the action,and so forth.  lf you would
like to expand your skillsas a photographerand have your friends
marvel at most all your photographs,then masteringthese few
simpletechniquesis well worth your while.
Optimu m Apertu res
The apertureguide listed on page 13 is sufficient for most shooting
purposesand correct exposurewill be obtained as long as the green
LED lights. However,with certain subjectsand to obtain certain
specialeffects,it is better to vary from the norm. Any aperture
setting may be used as long as the green LED continuesto light.
Stopping the Action: With fast moving subjectssuch as bicycles,
automobiles,horses,children at play, birds in flight, etc., a fast
shutter speed is necessaryto stop the action and prevent the subject
from blurring.Although the MV 1 does not feature a shutter speed
dial, you can easilystop the action by usinga wide lensaperture
where the red LED does not come on. (for example,f 12.8,f 11.7
etc.). As the cameraautomaticallychoosesthe fastestshutter
speedit can for the given exposure,it will freezethe subject

in daylightor in brightly lit arenasand stadiumsif you usea wide
maximum aperture.(This techniquedoes not work in low-lighting,
as low lighting necessitatesa slow shutter speed.)
Depth.of-FieldControl: Depending upon the aperture in use, different
areasin front of and behind your subject will be in focus. This is
known as depth of  f ield and its effect can be varied by changing
lensapertures.lf you need to know the critical depth of fields refer
to the depth-of-field scaleand tables on pages26 and 27. Often,
however,you can get by  if you rememberthe f ollowing.
Maximum Depth of Field: The depth of  f ield becomesprogressively
deeperas the lens is stop down to smaller aperturesand is greatestat
minimum aperture.Thus, if you desireboth your subject and
backgroundto be in focus, use a small aperturesuch as f/11 and
tl16 (if the yellow LED Lights,take precautionsagainstcamera
shake).Small aperturesare also useful for critical close-upwork,
but for this, refer to a close-upphotography guide.
Out-of-focushighlights: The depth of  f ield becomesprogressively
shallowerat wide lensapertures,and is shallowestatf 12,f 11.7or
f 11.4,dependingupon which is the maximum apertureof your
lens.A shallow depth of  f ield producesan out-of-focuseffect
which highlightsyour subject.Providedthe green LED remains
 lit, you can ohtain this effect by usinga wide maximum aperture,
evenon a sunshinydaY.

EXPOSURE COMPENSATION    www.orphancameras.com



When shootingin difficult lightingsituationssuch as when the subject
is situatedagainstthe light (direct sun, snow, a bright window) or
when spotlightedon stage,etc., either additional or lessexposureis
requiredto overridethe influenceof the strong backlightingand
bring out the detailsof the subject.Such problemsare easily
correctedby temporarily alteringthe setting of the ASA film speed
dial for the shot requiringexposurecompensation.

Backlit Subjects: For subjectswith the sun behind them, standing
againstthe light, bright snow, etc, compensateby loweringthe
ASA film speedvalueto half or four times the ASA film speed.
F o r e x a m p l e :
      With ASA lOO film in the camera: reset the dial to ASA 50 or
     ASA 25 (this gives2x and 4X compensation,respectively).
      with ASA 400 film: reset the ASA diar to ASA 2oo l2xl or
     ASA 100 (4X ).
Spotlighted Subjects: For subjectson spotlighted stage,etc., decrease
your exposureby doubling or quadruplingthe ASA film speedvalue.
For example:
      With ASA 100 film: resetthe dial to ASA 2OO nl2xl
       or ASA 400 n l4Xl .
      With ASA 400 film: resetthe dial to ASA 800 nnX)
       or ASA 1600 n l4xl
Always reset the ASA dial to its original setting after employing
exposure compensation.
                                                                                              24.
