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.4www.butkus.org

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 cocked. 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.


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.

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 cocked. 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.4www.butkus.org

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).

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 Apertu re 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".)

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.4www.butkus.org 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.

(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.

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.

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.4www.butkus.org

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.

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.)
