Honeywell Pentax SP 500
This is the Pentax SP 500—another proud member of the world-famous Pentax family whose name has become synonymous with design innovations and precision craftsmanship in 35mm single-lens-reflex cameras. When the first Pentax Spotmatic was introduced to the public at the 1960 PHOTOKINA, the world's largest photographic fair, in Cologne, Germany, it attracted the instant and close attention of photographers and photographic engineers alike. Not available for purchase at that time, it was a model of the advanced design and features that would be incorporated into cameras of the future. Pentax cameras and other brands as well. Several years of extensive research preceded its introduction, and four more years of research and experimentation. followed before the meticulous Pentax engineers and technicians felt the camera was truly ready.
At last, in late 1964, it reached the eager hands of serious amateur and professional photographers around the world. Like that early Spotmatic your Honeywell Pentax SP 500 is a computer camera. Hidden Within its body, its unique, behind-the-lens exposure meter utilizes two highly sensitive Cadmium Sulphide sensors to accurately measure the light gathered by the camera's lens as it is reflected from the subject being photographed. Therefore, by measuring the light as it passes through the lens and matching the exposure needle as seen through the viewfinder, you can be assured of properly exposed pictures under all but the most impossible lighting conditions. Whether you're using special, macro- or microphotographic lenses, telephoto lenses, or simply filters on normal lenses, your Honeywell Pentax SP 500 will give you correctly exposed photographs without the use of external meters or the need for difficult, time-consuming exposure calculations! Your SP 500 may also be set manually the same as any other quality 35mm camera if special lighting or selective focus effects are desired. Just leave the exposure meter switch in its OFF position and select the f/stop and speed settings for the desired effect. The traditional classic design and simple elegance associated with earlier models of the famous Pentax have been retained in the SP 500 despite the incorporation of many highly advanced features and many internal improvements that have been developed over the years.
Like the other members of the Pentax family, the Honeywell Pentax SP 500 has a 42mm threaded lens mount that accepts any of the superb Takumar lenses from the ultra-wide-angle 17mm Takumar to the super telephoto 1000mm Takumar, a wide range of optics that will satisfy the demands of even the most critical professional. Moreover, the list of fine accessories is always growing—to help you keep growing photographically.

Short-course operating manual
|
1. SET FILM SPEED. which appears alongside the figure 1. Then wound the rapid wind lever. 2. SET SHUTTER SPEED. 3. COMPOSE AND FOCUS.
|
|
|
|
4. TURN ON LIGHT METER SWITCH.
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. When the needle is off center and close to the (+) mark, you will get over-exposure: change the shutter speed to a faster setting. If the needle is closer to the (-- mark, you will get under-exposure: change the shutter speed to a slower setting.
|
6 RELEASE SHUTTER.
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.)
| 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. 1. Open the back by pulling out the rewind knob until back cover snaps open. 2. 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. 3. 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. 4. If the film is properly loaded, the rewind knob will turn counter-clockwise when you advance the film by turning the rapid wind lever. |

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. 2. 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. Wind the rapid wind lever for the first picture; the exposure counter automatically turns to '1', indicating that the first picture is ready to be taken. 3. 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. DON'T open the back of the camera, or all exposed frames will be ruined. |
4. Unfold the film rewind crank.
5. 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. AVOID DIRECT SUNLIGHT WHEN UNLOADING YOUR FILM. (The rewind release button will return to normal position as you lead your next film and turn the rapid wind lever.)
6. 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. 2. 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. In bright sunlight, you can easily focus with diaphragm closed to f/5.6 or f/8, and still observe the depth of field. 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. The preview lever may be moved back to "A" (automatic) position before or after making your exposure, or, if you are making pictures in bright sunlight, it may be left in manual position, which permits a constant ('heck of depth-of-field. |
|
| * When the exposure meter switch is turned to the "on position, the lens diaphragm changes from the automatic to manual position even though the preview lever is in the "A" (automatic) position. When the shutter is released, the lens diaphragm will automatically return to its automatic position if the lever is set on "A". | |
Shutter
|
Turn the shutter speed dial clock. wise or counter-clockwise to the shutter speed desired. 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 "wound" 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 17. With the shutter speed dial set on B (bulb), the shutter will stay open as long as you depress the shutter button. As you release your finger from the shutter button, the shutter closes. When a long exposure is desired while using the B setting, attach a shutter release cable with a locking device to the shutter button. This will permit a "Time" exposure. |
 |
Cautions
1. At slow speeds-slower than 1/30 - support your camera rigidly or use a tripod to prevent movement of your camera.
2. To protect the shutter mechanism, trip the shutter release before putting the camera out of use for any extended period.
Depth of field
 |
For example, if the lens opening of f/8 is to be used, the range on the distance scale ring covered within the figure 8 on the depth-of-field guide indicates the area in focus at the lens opening. You will note from the depth-of-field guide in the photograph that the range from approximately 10 to 25 feet is in focus. Depth of field is the range between the nearest and farthest distances which are in focus at different lens apertures. |
|
If you want to know how great the depth of field is at a certain aperture, look at the depth-of-field guide. In the above photograph, the distance scale is set at 15 feet . . . the lens is focused on a subject 15 feet 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 apertures. |
 |
|
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. The following table shows the range of the meter's light measurement, and should not be interpreted as the camera's total range of f/stop-shutter speed combinations. |
Mercury battery -
There are WEIN Air replacement batteries available that provides the accurate 1.3v needed.
|
|
|
|
|
How to check it
1. Set the shutter speed dial to B (bulb) position. 2. Turn the ASA dial to ASA 100. 3. Push the meter switch to "on" position. Look at the meters needle through the viewfinder. If the needle rapidly drops, the meter battery has sufficient capacity; if it does not, replace the mercury battery. How to replace it Open the battery housing cover on the bottom cover plate with a coin. Remove old battery and insert new battery with (+) side toward the top of the camera. For replacement, use Mallory PX-400 or RM-400-R or equivalent. |
CAUTION: The mercury battery is like a phonograph record. It can be damaged by skin acids. Handle by the edges with a dry cloth only. Be sure the battery is cleaned with the cloth before insertion into the camera. The battery is not rechargeable.
DANGER: A serious accident has been reported of a small child who has put a mercury battery (any button battery) into his mouth and has been hospitalized for serious gripes and stomach inflammation. Please, always keep a battery from the reach of small children
Webmaster: see my page on mercury batteries
Flash synchronization
| The Honeywell Pentax has two sets of terminals --FP and X. The table below shows which flash contact, which shutter speed and which flash bulb may be combined for maximum lamp efficiency. Unless these combinations are rigidly followed, there will be a failure in flash synchronization. Note the "X" setting is exactly at the 60 marked on the speed dial. This indicates the highest shutter speed at which Honeywell Strobonars or other electronic flash units may be used. |

Important notes
1. Always keep the meter switched off when not actually taking readings. Leaving the meter switched on will rapidly exhaust the battery. It is also necessary to keep the meter switched off when mounting a Super-Takumar lens on the Spotmatic camera body. If it is switched on, the tip of the automatic diaphragm release pin of the lens will hit the pin release plate inside the camera body and it may get damaged. 2. When the index of the shutter speeds turns to red, it indicates that the shutter and film speed settings are off the meters measurability range. Change the shutter speed setting to a faster or slower setting. Refer to page 15. 3. When the meter is switched on, the lens any Super-Takumar lens) is in its manual position even when the diaphragm preview lever is in "A" (automatic) position. When the meter is switched off manually, or automatically after shutter release, the lens returns to its automatic position when it is set in "A" position. |
 |
4. Exposure increase factors which apply when taking pictures with filters, close-ups, macro- and micro-photos. do not apply to the Spotmatic. 5. The length of the tripods screw should not exceed the normal length of 3/16" 4.5mm). Do not extend it longer than this length when mounting your camera on tripod. Forcing longer screws into the tripod socket of the camera will damage the mechanism. 6. We do not guarantee the quality of photographs when brands other than Takumar lenses and Pentax accessories, such as lens extenders, are used. |
 |
If you intend to take infra-red photographs, remember to use the small "R" index marked on the depth-of-field guide. First, focus your lens on your subject. Determine the lens to subject distance from the distance scale. Then match your lens to subject distance to the "R" mark by turning the distance scale accordingly. For instance, if your subject is in focus at infinity, turn the distance ring and move the infinity (oo) mark to the "R" index. The "R" index marking on the Takumar lenses is based on the lens setting at infinity. |
| For deliberate double exposures, make the first exposure in the normal way. Then tighten the film by turning the rewind knob A, and keep hold of the rewind knob. Depress the film rewind release button ~ and wind the rapid re-wind lever. This tensions the shutter without advancing the film. Finally, release the shutter to make the second exposure. Then make one blank exposure, before taking the next picture, to avoid overlapping. |  |
Regardless of the lens selected for your Honeywell Pentax, there is never need for an accessory viewfinder, ordinarily required for rangefinder type cameras. When interchanging lenses, hold the lens by the distance scale ring. When attaching a lens, filter, or lens hood, do not screw it too tightly, as you may find it difficult to remove.
FIXED FOCUSING SETTINGBecause of the considerable depth of field of wide-angle lenses, you can use them as fixed focus lens-if the diaphragm and distance scales are set properly. For your convenience, the Super-Takumar lenses shown on page 22 have a fixed focus mark. Just align with the index the orange-colored figures of the diaphragm and distance scales, and the lens will be in fixed focus from foreground to infinity. You'll find this extremely convenient for fast shooting.
Resolving Power of Takumar Lenses Resolving power of all Takumar lenses is factory-tested by skilled optical engineers. There are three types of tests: microscopic aerial test, projection test and photographed film test. Resolving power of a lens shown by LPM (lines per mm) varies depending upon the method of resolution test. Takumar lenses have been tested for resolving power to conform to Asahi Optical Company standards which are higher than those set by JIS (Japan Industrial Standards). All Takumar lenses bear the seal of the Japan Camera Inspection Institute which insures the highest standards of performance When testing your lens performance . . .Use a slow-speed fine grain film. Generally, high speed films are grainy and are not suitable for resolution test. Support your camera on a good tripod. Use a shutter release cable to prevent camera movement. The definition of the picture on the negative film may decrease if exposure and developing time are not proper. Time your exposure and development correctly. If you do your own developing and enlarging, see that your enlarger uses a fine quality enlarger lens. If it is not of a fine quality, your pictures can never be sharp no matter what superb lenses are mounted on your camera. Usually, the diaphragm of the enlarger should be closed down to f/8 or f/11. |

COMPLETE SYSTEM OF SUPERB TAKUMAR LENSES
 |
The extension tube set consists of 3 rings: #1, #2 and #3; 9.5mm, 19.0mm and 28.5mm respectively. These rings may be used in combination as desired. Ring #1 is suited for moderate close-up work as in copying documents. When all extension tubes are used simultaneously with the 55mm lens, the subject may be enlarged on the film to a magnification of 1.04 of the life size. Such extreme close-up photography is a special advantage of the single lens reflex camera because there is no parallax problem and you do not need an accessory viewfinder as is ordinarily required for rangefinder type cameras. By inserting any or all of the extension tubes between the camera body and the Takumar lens, subjects as close as 3 35/64 inches from the front of 55mm lens may be photographed. By adding more extension tubes, close-ups as close as the focal length of the lens may be easily and simply photographed. |
BELLOWS UNIT 11
| Double-track, De Luxe model bellows unit for extreme magnification. Mounted between your camera body and standard lens, you can obtain the maximum magnification of more than 3 times the life size. |
