O SHUTTER RELEASE BUTTON After the film has been advanced and the shutter releasehas been partially depressed,the battery circu it is tu rned on. lf the batteries in the camera are in good condition, the orange circle in the upper center of the viewfinder will light up. The , circle light will go out under normal lighting conditions,when the shutter release is fully depressedand the exposure made. The shutter releasecan be locked with a 30" clockwise turn of the shutter lock (page 5, part 5). lt is a good idea to lock the shutter if you do not releaseit after advancing the film. Eveit when the shutter is wou nd, the battery circu it is auto- maticafly disconnected. lt is connected only when the shutter a is released. O EXPOSURE COUNTER The counter is located on top of the camera (page 5, part 4) and indicatesthe number of film f ramesexposed. lt automati- cally resetsto "S" (for Start) when the camera back is opened. The 20th and 36th frames are in red to signal the end of the film roll (dependingon the length of f ilm used).View original page 10

O FILM SPEED (ASA OR DIN} SETTING After the film has been loaded,be sureto set the ASA or DIN film speedindex specifiedfor the film in useon the film speed scale. This adjusts the exposure control mechanismfor the film being usedand is an essentialstep in getting properly exposed pictures. To set the film speed,turn the Film SpeedRing (pageb, part 15) with your f inger on the notchesof the Film SpeedRing and align the white line at the outer top edge of the lens mount with the ASA speedof the film beingused.Click stops are provided to make settings easy. Do not set the .te betweenclick stops. Numberson the frlm speed,scalerepresentASA valuesonly and rangefrom ASA 2b to 800.

O THE LENSOF THE PETRI ES AUTO
The Petri ES Auto is suppliedwith a 40mm, f|1.7 Petrisemi-
wide-anglelens, specially designedf or fast shooting in the
poorest illumination and for greater-than-normalsubiect
coverage.
The lens has a 57"06' angle of view, 27o/ogreater than a
standardlens for a 35mm camera. Therefore,the Petri lens
will cover a much greaterareaon the samefilm frame.This is
extremelyusefulwhen photographinglargesubjectareasfrom

O HOW TO INSERT THE BATTERIES The Petri ES Auto uses two tiny, lightweight batteries to operatethe built-in, automaticCdS exposurecontrol system. HM-N, 1.4-voltbatteriessuchas EvereadyE-640or RM-640-H, or Maflory RM-640 or RM-640-Hcan be used. The battery compartmentis in the bottom of the camera(page7, part26l. To insertthe batteries,slidethe lid with your thumbnailin the directionof the arrow. Placethe batteriesin the compartment. Be sure that each battery is placed as shown in the battery compartment.The exposurecontrol mechanismwill not work if tl- e batteries are placed incorrectly. When you put the batteriesir, be sure to set the leadertape underthe batteries.View original page 14

O FULLY AUTOMATIC EXPOSURECONTROL
The Petri ES Auto with its built-in electronicshutter allows
shootingevenunder bad lightingconditions.
When the shutter button is depressed,the light striking the
Electric Eye CdS cell will be transmitted to the electronic
mechanismand the camerawill automaticallyselectthe proper
lensopeningand shutterspeed.
lf filters are used,no adjustmentin exposureis required,as the
filters fit over the CdScell abovethe lens. Just make surethat
the CdS cell is not obstructed during picturetaking by v/rur
finger or any other object.
NOTE: lt is important that the film speedindex specifiedfor
the film in use is set properly. (See F ILM SPEED
SETTINGon page1 1.)

The ExposureControl is simpleto operate:
1. Pushthe A/F Switch (page6, part 21l.to the right to set
it to " A" positionvisible.
Depressthe shutter button slightly. The lamps lighting
up in the orange circle in the viewfinder and in the
squareon top of the camera (page 5, part 8) indicate
that the batteriesare in good working condition.
When shootingsubiectsin normal light (more than EV
6.5) the lamps go out as you pressthe shutter all the
way down. This indicatesthat the shutter speedis fast
and that you can shoot without worrying about camera
shake,the causeof blurred pictures.

O HOW TO COMPOSE THE PIETURE
When you look through the viewfinder, you will notice a
bright yellow frame composed of four L-shaped lines, one ati
each corner. The frame is a fairly close approximation of the
actual area of the subject that will appear in your pictureI
under ordinary circumstances.Therefore, compose the subject
with in th is f rame.

O PARALLAX CORRECTION MARKS
When you look through the viewfinder, you will see three
yellow dots, two in the upper part of the frame on both sides
and one on the left-hand side of the lower part. They are
parallax correction marks. When you take portra its or close-
ups (subject within 10 feet of the camera), use the dots as the
border of the picture. See the illustration.
Th is correction is requ ired because the lens of the Petri ES
Auto, as those of most cameras, is located in a different po-
sition than the viewfinder. Therefore, the'viewfinder cannot
show the identical scene that the lens is taking. This ir :led
ParaI lax.
With most scenes, particularly those in which the subject is
more than 10 feet (3 meters) away, the parallax is of little
importance. lt is a considerationwhen you are taking portraits,
for instance, and you must compensate to avoid cutting
off your subject's head.

O HOWTO HOLD THE PETRI ES AUTO
The format of your picture is determinedby the position in
which you hold the camera.Holding the camerain a hori-
zontalpositionwill resultin a horizontalformat. Holdingit in
a verticalpositionwill resultin a verticalformat.
Blurring in a picture is often causedby camerashakeat the
moment of exposure.Practiceholding the camera and re-
leasingthe shutter smoothly so you can take pictureswithout
jarringor shakingit.
Thesethree simple rules will help you avoid camerashake:
1. Beforereleasingthe shutter,take a deepbreathand hold
it until the picturehas beentaken.
2. While taking the picture, hold the camerafirmly with
both hands and press the back againstyour face and

O FLASH PHOTOGRAPHY
The Petri ES Auto with its electronic shutter and automatic
exposure control system assures you of properly exposed
pictures, even with extremely poor light. However, when you
snap a MOVING object in poor light, it is necessaryto use
flash equipment becausea subject in dim light requiresa slow
exposurewithout flash and a mwing subject would be blurred.
Once the flash unit is connected, the shutter speed is then
automatically set at 1l2O sec.for f lash synchronization.
The Petri ES Auto is equipped with both a "hot shoe" contact
for cordless units and a standard PC socket for units with cord.
lf y j use a cordlessunit slip it into the accessoryshoe on top
of the camera and it will automatically make contact with the
shutter mechanism. lf your unit has a cord simply plug the
cord into the flash socket (page 5, part 17l-.
When Using NON-AUTOMATIC Flash Units:
1. Push A/F Switch to the right to set at wl"A" position
visible.
2. Set gu ide letters f rom " ^" to " G" (from table on
camera back)** to flash guide number ring (page,5,
part 14l. of lens. 23View original page 24Page 26 · Read text
of lens accordingto the instructionmanual of your
electronicflashunit.
2. With A/F Switch pushedto the right and " A" position
visible,the orangelight and arrow flash signalk I will
appearand the automaticflash unit will f ire WH EN-
EVER N EEDED.
3. When A/F Switch is set to the left and "F" position is
visible,the automaticflash will ALWAYS fire regardless
of light conditions.
O HOW TO USE THE SELF-TIMER
Sw, 3 the self-timer lever in the direction indicated by the
arrow in the illustration. Releasethe shutter button, and the
frame will be exposed after a delay of approximately I
seconds. The self-timer can be set either before or after
advancing the film. The self-timer is generally used when the
photographer wants to join a group that he is photographing.
The use of a tripod or similar support is recommended when
the self-timer is used and is essentialfor pictures taken at slow
speeds.
Do not use the self-timer in poor light (less than EV 2.51.

O MAINTENANCE AND CARE OF THE PETRI ES AUTO
A few simple precautions, careful handling and immediate
attention in case of trouble will prolong the life of your
camera and keep it operating well indefinitely.
Follow thesesimple rules:
1. To clean the outside of the cam era, use a soft brush first
and then a soft cloth.
2. Remove any dust or sand inside the camera with a lens
brush or a hand blower.
3. Dust, f ingerprints, water drops, etc., on the lens n .>nly
affect picture contrast but, if f eft for a long time, will
attack the surface.
4. Should your camera fall into water, immediate attention
is imperative. Bring it to a repair shop at once. If it falls
into salt water, rinse it thoroughly in fresh water and
then bring it to a repairman.
5. Your camera, when not in use, should be protected from
dampness and dusti keep it preferably in its case and, as
an additional precaution, in a polyethylene bag.
