ASAHI PENTAX SPOTMATIC MANUAL PDF

As well as a number of minor improvements to the meter components and film transport, the SP II was fitted with a HotShoe with a switch under the rewind crank for FP and X- flash synchronization and the ASA range was increased to It was only available in the North American market. It was the first version to offer open-aperture metering, but this needed the updated Super-Multi-Coated S-M-C Takumar lenses with an aperture-position linkage to the camera. The FP option for the hot shoe synchronisation was dropped and the meter circuit design was revised to take account of the lens aperture setting and to indicate correct exposure when zero current is flowing through the meter, which now allowed for a variation in voltage from the battery. The battery now needed extra capacity and was changed to the now-defunct PX mercury cell.

Equipped with FP and X flash terminals. Exposure Meter Built-in meter measures the brightness of the ground glass, and couples directly to shutter and film speed settings.

Meter is powered with a mercury battery. Film Rewind Rapid rewind crank for speedy film take-up. Film rewind release button on bottom of camera body rotates while film is being rewound. Weight grams 1 lb. Short-course operating manual 1. Lift the outer ring of the shutter speed dial, turn it around and set the same number as the ASA number of the loaded film to the small red index which appears alongside the figure 1. Then wind the rapid wind lever. Turn the shutter speed dial and set the speed you wish to use to the index.

When indoors, set it at 1 30, or in its neighborhood. Change the shutter speed later, when necessary. Refer to item 5, page While viewing through the viewfinder, turn the distance scale ring with your thumb and index finger until you get the sharpest image of your subject at the microprism center of the finder.

Push up the switch button with your thumb, and the small window on the switch button will turn to red indicating that the meter is switched on. Through the viewfinder, you will observe the movement of the meters needle on the right side of the ground glass.

Be sure to turn off the meters switch when not actually taking readings. The needle moves up and down with the turn of the diaphragm ring. When the needle rests at the center, you will get correct exposure, If the needle does not come to the center no matter how far you turn the diaphragm ring, change the shutter speed.

If the needle is closer to the -- mark, you will get under-exposure: change the shutter speed to a slower setting. Hold your camera firmly and trip the shutter. When the shutter is released, the meter switch will automatically turn off, and the needle will remain fixed off and underneath the center.

The diaphragm will reopen to its full aperture and the overall image will look brighter. Wind the rapid wind lever for the next picture. When taking a series of pictures under the same lighting conditions, it is not necessary to repeat instructions 4 and 5. How to hold your camera In horizontal position A.

Hold the camera firmly with your left hand, and draw your arm close to your body. In vertical position B. Hold your camera tightly to your forehead with your left hand, and draw your right arm close to your body. In vertical position C. Hold your camera tightly to your forehead with your left hand, raise your arm and draw your left arm to your body.

As a general rule, your camera should be held more firmly by the left hand which does not release the shutter. If you hold your camera with the right hand--the hand which releases the shutter--it may cause camera movement. Very often, pictures which are not sharp are due to movement of the camera.

When you focus with the camera held horizontally Position A , hold the lens barrel as illustrated in photograph. Put the camera on your left hand thumb and little finger. Turn the distance scale ring with your thumb and index finger. When holding the camera vertically, some people release the shutter with the thumb Position B , while others release it with the index finger Position C. Position C is more desirable for fast focusing and shooting. With the Honeywell Pentax, whether held vertically or horizontally, you see your subject image through the taking lens, enabling you to compose, focus and shoot with a minimum of time and effort.

Film loading Avoid direct sunlight when loading your film. Open the back by pulling out the rewind knob until back cover snaps open.

Place the film cassette into the cassette chamber, and push back the rewind knob. Draw out the film leader and crease across one or two perforations back from the end of the leader. Insert the creased portion into slot of the take-up spool. Advance the film by alternately turning the rapid wind lever and releasing the shutter until both sprockets have properly engaged the film perforations.

Close the back by pressing it firmly. If the film is properly loaded, the rewind knob will turn counter-clockwise when you advance the film by turning the rapid wind lever. Simply turn the dial so that the type of film in the camera is opposite the A mark. To check whether the camera is loaded, turn the film rewind knob clockwise. If it turns freely, the camera is not loaded. The ASA film speed rating of all 35mm films is given in the data sheet packed with each roll of film.

The higher the ASA number, the more sensitive the film. Lift the outer ring of the shutter speed dial and rotate it until the ASA number of your film is opposite the red index mark. Be sure to set your film speed on the shutter speed dial because the dial is connected to the exposure meter system. Film wind and rewind 1. Before turning the rapid wind lever, slowly turn the film rewind knob clockwise until a slight resistance is felt.

This prevents loosening or warping of the film. The first portions of the film cannot be used for picture taking as t hey have already been exposed to light.

Generally, two blank exposures should be made before taking your first picture. Wind the rapid wind lover until it stops. Watch to see that the film rewind knob turns counterclockwise, indicating that the film is moving from cassette to take-up spool. Trip the shutter. After the final picture on the roll 20 or 36 exposures has been taken, the rapid wind- lever will not turn all the way as you stroke it.

This indicates that the final picture has been taken on your film, and that the film must be rewound. Unfold the film rewind crank. Depress the film rewind release button. Turn the rewind crank to rewind the film into the film cassette. The film rewind crank permits rewinding at a smooth, even rate. Under some atmospheric conditions, erratic or too rapid rewinding will cause static electricity marks on the film. You will feel the tension on the rewind crank lessen as the leader end of the film slips off the take-up spool.

Stop rewinding when you feel this happen. The rewind release button will return to normal position as you lead your next film and turn the rapid wind lever. Pull out the film rewind knob the back will open automatically , and remove the film cassette.

Bright field focusing 1. You can start viewing and focusing before and after winding the rapid wind lever. When the preview lever is in "A" automatic position, and the meter is at "OFF the diaphragm is fully open except for the moment of exposure. Turn the distance scale ring until your subject image is clearly in focus.

It is not always necessary for you to view and focus with the diaphragm fully open. It is easier, however, to focus with the diaphragm fully open as your subject image is much brighter. When the letter "M" appears beside the lever, the lens is in manual position; when "A" appears, it is in automatic position. Microprism Honeywell Pentax cameras have a Fresnel lens with a microprism center underneath the ground glass.

As you look through the finder, you will see that the Fresnel lens consists of many concentric rings which provide the brightest possible image on the ground glass. The microprism is the center portion of this diagram. When your subject is in focus, the image in the microprism will be sharp and perfectly clear.

If your subject is not in focus, the microprism will break the image up into many small dots, much like an engravers screen. You can focus your subject on any portion of the ground glass. Automatic diaphragm When the preview lever is in "A" automatic position, and the exposure meter is turned to "OFF", the fully automatic diaphragm is at its largest aperture at all times, except for the instant of exposure, no matter what aperture is set on the diaphragm ring.

When you release the shutter, the diaphragm automatically stops down to the predetermined aperture and the shutter curtains start traveling instantly. When the exposure is completed, the diaphragm reopens to maximum aperture completely automatically and you are ready to compose, focus, and shoot your next pictures.

If you wish to visually check exact depth-of-field before making the exposure, move the preview lever to "M" Manual position. This stops the diaphragm to the aperture selected and shows you exactly how much depth-of-field will appear in your picture. When the shutter is released, the lens diaphragm will automatically return to its automatic position if the lever is set on "A".

Do not leave that switch on UP for a long time as it will drain you battery. Shutter Turn the shutter speed dial clock. The shutter speed may be set either before or after winding the rapid wind lever.

As you wind the shutter by turning the rapid wind lever, the "wind" indicator turns to red showing that the shutter is wound. The indicator window blacks out as you trip the shutter button. For use of the X setting on the shutter speed dial, refer to page

Page Shutter Turn the shutter speed dial clockwise or counter-clockwise to the shutter speed desired. Page Range Of Light Measurement Range of light measurement The exposure meter of the Spotmatic measures the brightness of the ground glass. Therefore, the meter should be turned on after you have focused your subject on the ground glass. As you will note from the table below, with an ASA film, you may use any shutter speed from 1 sec. A serious accident has been reported of a small child who has put a mercury battery into his mouth and has been hospitalized for serious gripes and stomach inflammation.
