SHOOTING ON AUTO





Exposure Check: After you have set the ASA  f ilm speed, preset the
aperture and focused, you are ready to check the exposure. Simply,
press the shutter button slightly until one of three LEDs in the
viewfinder lights. lf the green LED lights, go ahead and shoot.
Overexposure Warning: lf the red LED indicator lights on presseing
the shutter button partway, the photo will be overexposed. To
prevent this, you will have to reset the aperture ring to a smaller
aperture by turning  it clockwise until the green LED comes on (for,
example   f /8 to  f /5.6 or  f l4 etc'l-
Slow Exposure/Camera Shake Warning: lf the Yellow LED lights,
it indicates that the camera has selected a shutter speed below
1/30 sec. in relation to your preset aperture. This, does not necessary
indicate that the photo will be underexposed, but there is a tendency
for the picture to blur with such slow exposures. Usually, however,
blur also can be prevented by resetting the aperture ring. Only, in this

                                                       14o

 instance, you set the aperture ring to a wider aperture (smaller f_
 number value) by turning  it conterclockwise until the green LED
 lights. For example,  if it is set at f 15.6, turn it tof /4,f 12,etc.lf the
 green LED does not come on, even after you have set the lens to the
 widest aperture, do either of the following.
 use a tripod - Page 35 Switch to flash photography _ page 20_21
 Because the MV auto exposure system selects the shutter speed for
 you steplessly between 1/1000 and 1 sec. in relation to the aperture
 setting, the above is all you need to know about exposure control
 for satisfactory results with most subjects. However, for better
 results in diff icult lighting, shooting against the light, with fast
 moving subjects, etc., refer to the section ,'shooting pointers,,
 lPage 22l, when you feel you are ready to master special techniques
to use in such situations.

        It you shoulcJ happen to press the shutter button while the
      shLriter dial is set on AUTO with the lens cap on, or rn very
    poor liqhting conditions, the mirror may lock up, resultinq
      in abnormally long exposure. To correct this. the shutter
    can be cluickly closecJ by turning the shutter dial to 1OOX.
     After closin!J the shutter, be sure to reset the shutter clial
     to AUTO.

THE "IOOX" AND "8" SETTINGS



While the MV is designed almost totally for use on AUTO, two other
settings are provided on the exposure mode dial for special shooting
situations.
"100X" This manual shutter speed setting really need not be used
at all if you use the Pentax AF 200 S Auto Flash and keep spare
batteries on hand. lt is provided for manual  f lash synchronization
with ffish units other than the AF 2oo S (see page21)' In addition'
it may also be used in emergencies when batteries fail and you do
not have spare batteries on hand. For emergency exposures without
batteries, merely set the exposure mode dial to "100X" and select
the aperture according to the brightness of your subject (refer to the
exposure guidelines accompanying the  f ilm).
"8" (Bulb): This setting is used when desiring to make "Time"
exposures longer than 1 second. To use, first mount the camera on
a tripod, then, attach a cable release to the camera's shutter release
button. The shutter will open when the plunger of the cable release
is depressed and remain open as long as pressure  is maintained. For
ultra long exposures such as several minutes or hours, use a cable
release with a locking device.

HOLDING THE CAMERA


As a general rule, your camera can be held more firmly in the left hand, which does not release the
shutter. lf you hold your camera with the right hand - the hand that releases the shutter -  this maycause camera movement. Often, blurred pictures are due to camera movement.

UNLOADING FILM                    www.butkus.us


 After the last picture on the roll has been taken, the rapid-wind lever will not advance any further
 indicating that the film must be rewound. (Caution: do not try to force the lever any further.) Fold out
 the rewind crank. Depress the film rewind button i.-', aDd turn the rewind crank as indicated to rewind
 the film into its cartridge. Rewind until the tension on the crank lessens, indicating that the leader end
 of the film has been released from the take-up spool. Pull out the film rewind knob (the back will open
 automatically), and remove the  f ilm cartridge.

OTHER FLASH UNITS (CORDLESS TYPE)     www.butkus.us


 The MV may also be used with other  f lash units besides the AV 2OO S,
 provided they are the cordless type. These mount by sliding into the
 hotshoe on top of the camera in the same manner as the AF 2OO S.
 Flash Synch: Unlike the AF 200 S, however, other flash units do not
 synchronize automatically with the MV.
 Synchronize them manually by turning the exposure mode dial to
 "100X." Also note that the viewfinder LED flash ready indication  is
 not provided with other  f lash units.

As flash operating instructions vary depending upon the type of flash
unit you are using, refer to the instructions accompanying your flash
unit for  f lash mode setting, aperture setting, and other operating
instructions.

SHOOTING POINTERS


The basic instructions for shooting on auto are all you need to know
to obtain successful results for most all non-critical photography.
However, the MV is a sophisticated  single-lens-ref lex camera and, as
such, is capable of a wide variety of techniques which enable you to
obtain better results in difficult lighting situations, produce special
focusing effects, stop the action, and so forth'  lf you would like to
expand your skills as a photographer and have your friends marvel
at most all your photographs, then mastering these few simple
techniques  is well worth your while.
Optimum Apertures
The aperture guide listed on page 13 is sufficient for most shooting
purposes and correct exposure will be obtained as long as the green
LED lights. However, with certain subjects and to obtain certain
special effects, it is better to vary from the norm. Any aperture
setting may be used as long as the green LED continues to light.
Stopping the Action: With fast moving subjects such as bicycles,
automobiles, horses, children at play, birds in flight, etc., a fast
shutter speed is necessary to stop the action and prevent the subject
from bluring. Although the MV does not feature a shutter speed
dial, you can easily stop the action by using as wide a lens aperture
as possible without the red LED coming on. (for example,f 12.8
f 11.7 etc.l . As the camera automatically chooses the fastest
shutter speed it can for the given exposure,  it will freeze the subject
                                                    22.

 in daylight or in brightly lit arenas and stadiums  if you use a wide
maximum aperture. (This technique does not work in low-lighting,
 as low lighting necessitates a slow shutter speed.)
Maximum Depth of Field: The depth of  f ield becomes progressively
deeper as the lens is stop down to smaller apertures and is greatest at
minimum aperture. Thus if you desire both your subject and
background to be in focus, use a small aperture such as f 111 and
tl16 (if the yellow LED Lights, take precautions against camera
shake). Small apertures are also usef ul for critical close-up work,
but for this, refer to a close-up photography guide.
Depth of Field Control: Depending upon the aperture in use, different
areas in 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
lens apertures.  lf you need to know the critical depth of fields refer
to the depth of field scale and tables on pages 26 and 27.Often,
however, you can get by if you remember the following.
Out-of-focus highlights: The depth of  f ield becomes progressively
shallower at wide lens apertures, and is shallowest at 112, tl1.-7 or
Il1 .4, depen ding upon which is the maximum aperture of your
lens. A shallow depth of field produces an out-of-focus effect
which highlights your subject. Provided the green LED remains
lit, you can obtain this effect by using a wide maximum aperture,
even on a sunshiny day.

EXPOSURE COMPENSATION



When shooting in difficult lighting situations such as when the subject
is situated against the light (direct sun, snow, a bright window) or
when spotlighted on stage, etc., either additional or less exposure  is
required to override the influence of the strong backlighting and
bring out the details of the subject. Such problems are easily
corrected by temporarily altering the setting of the ASA  f ilm speed
dial for the shot requiring exposure compensation.
Backlit Subjects: For subjects with the sun behind them, standing
against the light, bright snow, etc. compensate by lowering the
ASA  f ilm speed value to half or four times the ASA  f ilm speed.
For exa'mple:  't-
      With ASA 100 film in the cam€ra: reset the dial to ASA 50 or
    ASA 25 (this gives 2X and 4X compensation,  respectively).
      Wath ASA 4OO film: reset the ASA dial to ASA 200 (2X) or
    ASA 100 (4X).
Spotlighted Subjects: For subjects on spotlighted stage, etc.,decrease your exposure by doubling or quadrupling the ASA  Hffi
film speed value. For example:
      With ASA 100 film: reset the dial to ASA 2OO n l2Xl
       or ASA 4OO 11 l4xl.
      With ASA 400 film: reset the dial to ASA 800 (1 /2X)
       or ASA 1600 (1l4xl
 Always reset the ASA dial to its original setting after employing
 exposu re com pensation.
                                                                                 24.

 Exposure-Compensation-lndicator   Dial: you may also use the
exposure-compensation-indicator  dial located under the film
rewind crank as a guide  f or exposure compensation. To Use:
 Fold out the  f ilm rewind crank as if to rewind the  f ilm and lift
the knob slightly to expose the exposure-compensation-indicator
dial. (CAUTION: BE VERY CAREFUL NOT TO pULL HARD
AS THE BACK COVER WILL SPRING OPEN, EXPOSING
YOUR FILM.) Next, turn the top of the dial with you  f inger until
the index mark of the exposure compensation dial aligns with ihe
ASA index mark and the ASA number of the film loaded in the
camera (lllust.   ). When properly aligned,  lif t the ASA dial ano
reset it as follows for exposure compensation.
      For 2X compensation: To the  f irst dot on the indicator,s
       plus side (lllust.    ).
       For 4X compensation: Second dot on the plus side.
      For 1/2X compensation: First dot on the minus side.
      For 1/4X compensation: Second dot on the minus side.
After setting the compensation, push the film rewind crank
shaft back in place and take the picture. BE SURE TO RESET
THE ASA FILM SPEED DIAL TO AGREE WITH THE FILM
LOADED IN THE CAMERA WHEN COMPENSATION IS NO
LONGER REOUIRED.

DEPTH-OF.FIELD SCALE



Depth of field is the range between the nearest and farthest
distances which are in focus at a given lens aperture.
lf you want to know how great the depth of field is at a certain
aperture, focus on the subject and look at the depth-of-field scale
on the lens. In the photograph below the distance scale is set at
5 meters; that is, the lens is focused on a subject 5 meters away.
The calibrations on each side of the distance index correspond to
the diaphragm setting and indicate the range of in-focus distance
for different lens aperture.
For example,  if a lens opening of ll4 is to be used, the range on the
distance scale ring covered within the figure 4 on the depth-of-field
scale indicates the area in focus at that lens opening. You will note
from the depth-of-field scale in the photograph that the range from
approximately 4 to 7m is in focus. Note that as the lens apertures
change, the effective depth of field also changes. For the depth of
field at different apertures and distances, refer to the next page.
