The lens is a Topcor 60, f2. F stops are from 3. Filters are the typical Bay 1 type. Film setting is by the red window to frame 1, and then it is automatically indexed. When first installing film, wind the crank until the number 1 appears in the red window in the back of the camera, depress the button above the wind crank and slide the button next to is towards the back of the camera.
This set the frame counter to 1, then film indexing automatically occurs every time the film crank is wound. Focus is by knob with an ASA reminder dial in its end. Above the focus knob is a Depth of Field scale. The film chamber is baffled for flare control. The ground glass has a fresnel lens with center focus spot and cross hair etched lines for aid in composition.
Back to Cameras. Used the heck out of it through high school and college and still have it. Pentax has most of their current and classic camera manuals online for free as PDF files Polaroid Corporation - has some of their older camera manuals including SX online. Grab these before they go broke! Web Photoethnography. Leave a comment. Email Address. Remember personal info? The only other accessory I had for my Sawyer was the bayonet mount flash shoe.
I have this vague recollection that neither the flash nor the shoe was stolen when my Mark IV went awol in , in part because mine had a broken PC socket, so I wasn't using flash with it. I think I saw the flash somewhere around the basement recently, and if the mount is with it, I'll offer it up here as a fresh freebie, but I suspect it's gone. No bracket there. Matthew Currie , Apr 3, BTW, any idea why the metal plating I assume? Almost seems that metal look was painted on Bummer To operate the Indicator, press down and turn the milled button in the center of Focusing Knob The same operation as detailed above has to be followed in case the film is taken out of the camera before 12 exposures are completed.
After the camera has been loaded, operate Film Winding Crank 13 with one continuous "down-and-up" pendulum swing. In other words, avoid transporting the film with short jerky motions. The amount of light admitted into the camera is controlled by 1 the length of time the shutter remains open and 2 the size of lens opening or "F-stop" as it is sometimes called.
Since the amount of light required to reproduce the image on the unexposed film is fixed, the shutter speed and F-stop are interdependent. Stating this in other words, a small lens opening represented by a high F-stop number will require longer light admission time, i. Conversely, a fast shutter speed will require a larger lens opening. The shutter speed is set by moving Shutter Speed Setting Lever 12 to the required position. The lens opening is indicated in black numerals and represents the following F-stop values 2.
Most light is admitted on the lowest value of the scale, i. In photographing a picture-subject, there are three factors which must be taken into account; namely, the brightness of the object to be photographed, whether it is in motion, and the speed or sensitivity of the film used.
To obtain a good photograph it is important to ascertain the proper combination of shutter speed and lens opening before exposing the film. This is done either by setting the shutter speed and lens opening separately or by setting the light value index only. Determining Proper Exposure by the Light Value System: It has been said in the foregoing that shutter speed and lens opening are interdependent.
Since the lens opening determines, in part, the near and far limits of sharp focus and since the shutter speed must take into account the rate of speed of a moving object, the problem of obtaining the proper F-stop and shutter speed combination has heretofore been a source of perplexity to most beginners.
A light value index simplifies this by representing the correct relationship between the shutter speed and lens opening with one number or index. It is determined with an exposure meter with a light value scale or by following the exposure chart provided for in the final page of this operating instructions.
To obtain the correct exposure, this index is transferred to the corresponding index on Light Value Scale 7 of the camera. Movement of Shutter Speed Setting Lever 12 will automatically change the lens opening within the limits of the same light value index and since the two are coupled, various combinations of proper shutter speed and lens opening are obtained for correct exposure under various conditions. The table on page 19 shows in chart form the inter-relationship between shutter speeds and F-stops for the various light value indexes.
NOTE 1. Therefore, if the light value reading on the exposure meter happens to be "5", it will be necessary to move Shutter Speed Setting Lever 12 to a slower speed in order to bring Combined F-stop and Light Value Setting Lever 6 within its free travel range. This, however, does not affect the correct exposure since, with the exception of 1;' sec.
This, in effect, decreases the lens opening to the next higher F-stop value and compensates for over-exposure. Conversely, if it is desired to change from 1,' sec. There are four basic positions of holding the camera for viewing and composing the picture; namely, waist level, eye level, above eye level and ground level.
Focusing with the Reflex View-finder Under most conditions the best method of focusing this camera is to look at the image on the Focusing Screen. The image appearing there is identical to what will be exposed on the film. To Open the Focusing Hood 1. Lift the rear edge of Focusing Hood 1 until it springs up into full open position.
To Use the Magnifying Glass. Magnifying Glass 17 is raised into position by pushing the upper edge of Eye-level View-finder Frame Plate 2 inwards. This will snap it into position. The eye should be brought as close as possible to Magnifying Glass 17 to obtain "hair-line" focusing. This glass has a magnification power of 2. It can be easily snapped back into lowered position by a light pressure on its outer edge.
Focusing with the Direct View-finder In addition to the reflex view-finder method, it is also possible to focus this camera by using Distance Scale 26 and composing the picture through the Eye-level View-finder. Under this method, the distance from the picture-subject to Taking Lens 8 is measured, or estimated, and the resulting footage is read off on Distance Scale 26 directly below the "2.
This method is commonly used for fast-action photography. To Use the Eye-level View-finder. Raise Magnifying Glass 17 as directed above. Press Eye-level View-finder Frame Plate 2 all the way down until it locks in the lowered position.
Sight through Eye-level View-finder Rear Sight 19 and compose the picture. Be sure to lower Magnifying Glass 17 before folding Focusing Hood l. This error is due to the difference in the vertical positions of the Viewing Lens 5 and the Taking Lens 8 in relation to the picture-subject and is called "parallax".
The two short lines etched horizontally on the upper edge of the Focusing Screen mark the upper limits of the picture composition and in taking close-up shots, care should be exercised to keep the reflected image below these lines.
