BATTERY FOR THE CdS EXPOSURE METER
The built-in CdS exposure meter is powered with a 1.3 volt mercury battery
(Mallory RM 675R, National M-1C, Toshiba TM-KC or equivalent). The battery
compartment is located on the left-hand side of the top cover. The exposure meter is
switched on by a stroke of the film advance lever. When the exposure meter needle
does not respond to a change of light conditions, the battery has become exhausted
and must be replaced.
Unscrew the battery compartment cover with your finger tips or a coin and insert a
new battery with the plus (+) upward, facing battery compartment cover, into the
battery compartment.
(Mercury batteries are no longer available. Use Wein Air batteries or adapters that
change standard button batteries to 1.3v.View original page 9Page 10 · Read text
FILM WIND LEVER
When the film wind lever is advanced, the following things happen
simultaneously:
1. The battery switch is turned on and the exposure meter is
activated.
2. The film frame is transported to the next unexposed frame.
3. The film counter is advanced.
4. The shutter is wound.
After the shutter is released, the battery circuit is shut off and
unnecessary battery drain is avoided.
EXPOSURE COUNTER
The counter is located on top of the camera body. It shows the number of film frames exposed, and automatically resets to ''S" (for "Start") position
when the back cover is opened. Frames of the 20th and 36th are marked in red to signal end of the roll, depending on the length of the film used.View original page 10Page 11 · Read text

FILM SPEED (ASA OR DIN) SETTING
After the film has been loaded, be sure to set the ADA or DIN film speed index
specified for the film in use on the film speed scale. This adjusts the exposure
meter for the film being used and an essential step in getting properly exposed
pictures.
To set the film speed, raise the external ring of shutter speed dial and turn to align
the reading equivalent to speed of the film in use with the index mark. Do not set in
between click-stops. If the reading does not align correctly, the ring will never drop
down. The black numbers represent ADA values and range from ADA 25 to 800,
and the red numbers represent DIN values ranging from DIN 15 to 30. Read the
instructions supplied with the film and set the correct film speed index number. If
the number of the film speed corresponding to that of your film is not available on
the film speed scale, use the closest number and never set between two settings.
For convenience, the positions for intermediate film speeds are shown only by
dots. See the illustration.View original page 11Page 12 · Read text
SHUTTER SPEED DIAL
Your camera shutter has a range of speeds covering sufficiently all the ordinary picture
situations. It has the settings of: 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4 and 1/2
second and Bulb. When the Bulb setting is used, the shutter stays open as long as the
shutter button is being depressed ( f or time exposure).
The settings are represented on the shutter speed dial located right-hand on top of the
camera body. For convenience, only the lower half of the numbers (250 for 1/250, etc.)
and B (for Bulb) are etched on the black wheel. The shutter speed is set by lining up the
appropriate number or B with the black line on the Pentaprism cover. Do not set the
shutter speed between two click-stops. The shutter speed can be selected either before or
after the shutter has been wound.
For indoor photography, it is recommended to set the shutter at 1/30 or 1/60; for outdoor
photography, at 1/125 or 1/250; and for action photography such as in sports or snap
shots it is important to use faster speeds of 1/250 or 1/500 to avoid blurring. The number
"15" for 1/15 second is larger than others and painted in fluorescent. When using the
shutter speeds slower than 1/15 second, it is recommended to use a tripod and a cable
release equipment so as to avoid camera shake.View original page 12Page 13 · Read text

DIAPHRAGM SCALE (APERTURE SETTING)
The diaphragm scale is located on upper side of the lens barrel and there
is an "EE" mark in red letter on it. When the diaphragm is set at the
"EE" mark, the camera automatically selects the optimum aperture
opening corresponding to the amount of light entering the lens. The
proper aperture opening the camera has selected is indicated by the
needle in the viewfinder.
The aperture opening has seven settings, ranging from f/1.8, the
maximum opening, to f/16, the minimum opening. For further
information as to the diaphragm scale, see MANUAL EXPOSURE
CONTROL IN THROUGH-THE-LENS SYSTEM (page 15).View original page 13Page 14 · Read text
FULLY AUTOMATIC EXPOSURE CONTROL IN THROUGH-THE-LENS SYSTEM
Set the aperture at "EE" mark in red letter on the diaphragm scale. This is all you
have to do for exposure control. By setting the aperture at the "EE" mark, the auto
and manual diaphragm lever is automatically switched to the "A" position (fully
automatic operation) even in case it is being set at the "M" position in green (manual
operation). Thus, the exposure control is done with the full aperture opening and the
viewfinder is always seen bright for easy and accurate focusing. (This is called "Open
Aperture System. )
The light entering Through-The-Lens strikes the two CdS cells located on each side
at the base of the Pentaprism (see the diagram) and the CdS cells measure the average
brightness of subjects you frame in the viewfinder. (This is what is called "Through-
The-Lens metering system".)View original page 14Page 15 · Read text
www.butkus.us The B (bulb) setting is not usable in the Electric Eye photography. Switch the diaphragm to the manual operation and set the diaphragm by turning the diaphragm scale. The stopped-down light measuring is applicable to the 55mm 1J, standard Electric Eye lens, but not to other interchangeable Electric Eye lenses. EXPOSURE WARNING MARKS In the viewfinder there is a diaphragm scale and on each end of the scale you will notice the red zone. The red mark above the f/16 is an over-exposure warning mark, and the one below the f/1.8 is an under-exposure warning mark.View original page 15
Page 16 · Read text
(1) OVER-EXPOSURE
When the exposure meter needle swings down to the over-exposure warning mark, it shows
"overexposure". Set the shutter at a faster speed or use an appropriate filter to absorb the amount of
light. (For the proper filter, see page 33.)
(2) UNDER-EXPOSURE
When the exposure meter needle jumps up to the under-exposure warning mark, it shows
"underexposure". Set the shutter at a slower speed. However, at the slower shutter speed than 1/15
second, it is recommended to use a tripod to avoid camera shake. When the meter needle won't
come down to the diaphragm scale in the viewfinder, it shows that the amount of light entering the
lens is extremely poor for the normal photography. Use flood illumination or switch to the flash
photography (see FLASH PHOTOGRAPHY at page27).
IMPORTANT
Make sure that the film speed is set at the correct reading specified for the film in use.
(For further information, see FILM SPEED SETTING at page 9 .) The automatic exposure control is not applied to the flash photography.View original page 16Page 17 · Read text

MANUAL EXPOSURE CONTROL IN THROUGH THE-LENS SYSTEM
There is a "M" (short for Manual) mark in green letter
around the upper side of the lens barrel, and the auto and
manual diaphragm lever (do) which switches the diaphragm
to "M" position from "A" (short for Automatic) position is
located on the opposite side of the "M" and "A" marks.
Move the auto and manual diaphragm lever to the left, and
you will see the diaphragm is set at the "M" position. The
manual operation is used in the following photographic
situations:
TO ADJUST THE EXPOSURE CONDITION
When the main subject of the whole picture area you frame in the viewfinder is extremely dark or bright, it is recommended to adjust the exposure
condition so that the important subject is correctly exposed. Set the exposure at the "EE" control and read the F number in the viewfinder. Then,
swing the auto and manual diaphragm lever to the left and set the diaphragm on the "M" position. If the important subject is comparatively dark, set
the f/number at a half or one stop closer to the full aperture than the f/number indicated in the viewfinder when you have set the exposure at the "EE"
control. If the subject is brighter, set the f/number at a half or one stop closer to the minimum aperture than the f/number the "EE" control let you
know. For example, when you take a portrait with a back-ground of snow scene or on the beach, you can get a properly exposed picture by using a
half or one stop wider aperture opening than normal.
TO CHECK THE DEPTH OF FIELD
Setting the auto and manual diaphragm lever on the "M" position you can pre-view the depth of field and see in the viewfinder the lens zone of
sharpness with any aperture.
TO TAKE CLOSE-UPS
When you use a close-up unit such as the extension, tubes or the extension bellows, the automatic exposure control does not work. PETRI FT EE,
however, has a means of obtaining a proper exposure setting.View original page 17Page 18 · Read text
Look through the viewfinder, and you will see a small blue dot very close to the f/2.8 in the diaphragm scale. This is the exposure indication mark. First, set the diaphragm on the "M" position and select an appropriate shutter speed. Then, looking through the viewfinder swing the diaphragm ring as far as the meter needle comes on to the exposure indication mark in the diaphragm scale. Through these procedures you can get the optimum exposure setting. If the meter needle stays above the mark, use a slower shutter speed, and if it stays under the mark, use a faster speed. NOTE: In manual exposure control, the diaphragm ring should be swung between f/1.8, the largest aperture, and f/16, the smallest aperture. If you have inadvertently swung it to the "EE" mark on the diaphragm scale, the diaphragm is consequently switched to the position in the automatic exposure control. So, switch the diaphragm to the "M" position again. TO USE NORMAL LENS When you use the normal lenses that are not designed for the "EE" photography, the automatic exposure control does not work. However, you can obtain the proper exposure reading 'through the procedures stated in TO TAKE CLOSE-UPS (Page 16 ). As to the Petri interchangeable lenses designed for the "EE" photography, see PETRI INTERCHANGEABLE LENSES at page 31. IMPORTANT: Make sure that the film speed is set at the correct reading specified for the film in use. (For further information, see FILM SPEED SETTING at page 9.) EXPOSURE METER COUPLED RANGE PETRI FT EE has a fully coupled CdS exposure meter which measures optimum exposure conditions Through-The-Lens, ranging from EV 3 to EV 17 with ASA 100 (DIN 21) film. HOW TO READ THE CHART The word "EV" stands for "Exposure Value" which represents the brightness on the subject you frame in the viewfinder. The EV is represented by numbers, sure meter of the PETRI FT EE can measure the brightness on the subject ranging from EV3 - EV17, when you use the film speeded at ASA 100 (DIN 21). For example, if the exposure meter needle stays around f/5.6 with shutter speed of 1/125 second (the film speed dial is set at ASA 100) in the EE photography, the brightness on the subject is supposed EV 12. If the brightness is at EV 12, you can use every one of six different shutter speeds and get properly exposed pictures. If you change shutter speed from 1/125 second to 1/250, owe stop faster, the diaphragm is automatically altered from f/5.6 to f/4, one stop smaller aperture. Thus, you can use six different shutter speeds ranging from 1/500 second to 1/15 second (see the chart) when the EV is at 12.View original page 18

www.butkus.us
What shutter speed you should use depends on the condition of subject. (Refer to SHUTTER SPEED DIAL at page 10.) The diaphragm opening
should be also decided according to the purpose of your photography. (Refer to DEPTH OF FIELD at page 20.)
SHOOTING AGAINST THE LIGHT
When the light is available from the back of the subject and your main
subject is comparatively darker than the back-ground, it is recommended
to adjust the exposure condition. The procedure is same as required when
the important subject is dark. (Refer to TO ADJUST THE EXPOSURE
CONDITION at page 15.)
First, set the exposure in the EE photography and read the f/number in the
viewfinder. Then, rotate the diaphragm ring to the right and set the
f/number at a half or one stop closer to the full aperture than the f/number
indicated in the viewfinder when you have set the exposure for the EE
photography.
VIEWFINDER AND FOCUSING
PETRI FT EE has the original PETRI Micromatic Focusing system for fast and
accurate focusing. The precision focusing elements in the viewfinder consist of
a group of more than 800 micro-prisms as shown in the center of the picture.
As you look through the micro-prism area (A) in the viewfinder, you can see the
subject clearly, ON LY when it is correctly focused. Rotating the focusing ring
you will notice the appearance of something like a mesh of a net in the center of
the viewfinder. This reticulation is caused by the flickering of reflected light
entering the camera lens. When the subject is correctly focused the flickering
grid fades away from the micro-prism area. In the second inner circle (B) is the
plain glass area where the subject is always seen sharp and clear, even when the
lens is out of focus. When the lens is correctly focused the image in the micro-
prism area will be as sharp and clear as that seen in the surrounding circle (C)View original page 19Page 20 · Read text
DEPTH OF FIELD
A lens that can be focused lets you accentuate the important image in a picture,
while it can de-emphasize irrelevant objects in front of and behind the main
subject by throwing them out of focus. This involves what is known as "Depth
of Field". The smaller the aperture is the more the depth-of-field increases.View original page 20Page 21 · Read text
www.butkus.us HOW TO READ THE DEPTH OF FIELD The scale is engraved on the lens barrel of your camera and indicated in black lines spreading out both sides of the index marker at the center. Simply focus the lens in the normal way, and each pair of black lines which points to the diaphragm scale indicates the depth-of-field zone corresponding to the diaphragm you set. For example, the depth-of-field zone for the standard 55mm lens is indicated as follows: When the focusing distance is 8 feet and the f/11 is selected, one of black lines at f/11 points to 6 feet, the nearest point still in focus, and the other points to approximately 12 feet on the other side, being the furthest distance in focus. PETRI F/1.8 55mm DEPTH OF FIELD TABLEView original page 21
Page 22 · Read text
The figures corresponding to 8 feet and f/11 are shown as 6.15 and 11.45, that is 6.15 feet, the nearest point in focus, and 11.45 feet, the furthest
distance in focus.
HOW TO HOLD YOUR PETRI FT EE CAMERA
The format of your picture is determined by the position in which you hold the
camera. Holding the widest part in a horizontal position will result in a horizontal
format. Holding the widest part in a vertical position will result in a vertical format.
Blurring in a picture often is caused by camera shake at the moment of exposure.
Practice holding the camera and releasing the shutter so you can take pictures
without jarring or shaking it.
Use the following three simple rules for taking a picture to avoid camera movement:
1. Before releasing the shutter, take a deep breath and hold it until after the picture
has been taken.
2. While taking the picture, hold the camera firmly with both hands and press the
back against your face and forehead as firmly as possible.
3. Squeeze the shutter release button, do not prod or tap it. Practice squeezing until
you can release the shutter without the slightest quiver.
