3. To set the shutter speed, just turn the Shutter Speed Selector until the number you want click-stops opposite the Shutter Speed Mark (red dot on the camera body).

4. Since different combinations of lens aperture and shutter speed can give equivalent exposures, best results are obtained by using the combination that is ideal for the picture you are taking. For example, if you are shooting a fast-moving subject, use a fast shutter speed with a large lens aperture and if you are shooting a subject having considerable depth, use a slow shutter speed and stop the aperture far down. 4www.Butkus.org

Equivalent Exposures Example

5. To avoid camera movement, use a tripod and a cable release for shooting with a shutter speed of 1/30 sec. or slower.
A cable release with stopper is available for shooting with the Shutter Speed Selector set at B. The stopper will keep the shutter open for as long as you wish.

FOCUS THE LENS

The Viewfinder is provided with an eyepiece for those with normal vision. If you are near-sighted or far sighted, be sure to use an Eyesight Adjustment Lens, otherwise it will be extremely difficult for you to focus the lens precisely. Four different Eyesight Adjustment Lenses are supplied as optional accessories: +2, +0.5, -2.5 and -4 dioptor.

(3) Microprism Focusing
Turn the Focusing Ring until the image in the microprism center spot appears sharp.

(4) You can also focus with any part of the area surrounding the microprism center spot. This method is especially useful when shooting with aperture stopped far down.

(5) The white numbers on the Focusing Ring are for meters and the green numbers are for feet. The distance can also be set by visual judgment for quick shooting.  When shooting extreme close-ups, the distance from subject to Film Plane Indicator must be precisely measured with a tape measure. 4www.Butkus.org

1. Look through the Viewfinder and touch the Shutter Release Button very lightly. You will see 1 or 2 diode lights in the right hand side. 2. Turn the Aperture Selector Ring until the diode light opposite the center of the Exposure Indicator is turned on. Even if you see 2 diode lights, center and above center or center and below center, you will have the correct exposure if the brightest one is the center light. 3. You will occasionally see 3 diode lights at the same time (especially when shooting under fluorescent light, or when shooting wide open scenes in bright sunlight), but the brightest light is always the main light. When the brightest light is brought into the center of the Exposure Indicator, you have the correct exposure.

4. If the diode light is seen above center (+ side) of the Exposure Indicator and you cannot move it to the center (opposite the bottom of the V), by turning Aperture Selector Ring, the shutter speed will have to be increased. If the diode light is seen below center (- side) and you cannot move it to the center with the Aperture Selector Ring, the shutter speed will have to be reduced.

5. If you are using a lens other than one of the Fujinon interchangeable lenses designed for the ST801, the light is measured through the stopped down aperture. First press down the Depth of Field Button and lock it by turning it to the left. Next, touch the Shutter Release Button very lightly and turn on the diode light located in the center of the Exposure Indicator by turning the Aperture Selector Ring. (The diode light will not move unless the Depth of Field Button is depressed).

Note: The diode light will not change unless the camera lens is properly mounted and locked. 4www.Butkus.org

SUTTER RELEASE BUTTON LOCK

The Shutter Release Button can be locked by pulling it up and turning it to the right. This . is a safety against turning on the battery and releasing the shutter inadvertently. The shutter can be released with a cable release with the button locked.

REWIND AND UNLOADING THE FILM

1. Press in the Film Rewind Button.	2. Unfold the Film Rewind Crank and turn it in the direction of the arrow. The crank will suddenly feel light when the entire roll of film has been rewound.	3. Next, lift the crank up to open the Camera Back, unload the cartridge and send it to a processing laboratory as soon as possible.

2. If the end of the film is reached when the Film Advance Lever is wound only halfway around, do not force it through, because the film might break. Just push it back to its normal position, and rewind the film into the cartridge.

Your FUJICA ST801 takes a complete series of FUJINON interchangeable lenses specially designed for this camera. It will also take the interchangeable lenses for the FUJICA ST701 as well as any other lens with a Praktica screw mount. With an adaptor on, it will also take lenses with a Leica mount. However, with lenses other than those designed specially for the camera, the light is measured through the stopped down aperture. 4www.Butkus.org Using Fujinon Interchangeable Lenses. 1. To remove a lens, push back the Lens Safety Lock Release Button in the direction of the arrow and turn the lens barrel to the left (counterclockwise). Just 2 1/2 complete turns will release the lens. 2. To mount, just screw the lens in turning it clockwise until it stops with a click.

OTHER LENSES 1. To mount, screw the lens in until it feels tight and the Distance/Aperture Indicator on the lens comes directly on top. About 2'/z-3 complete turns should be enough. If the Indicator on the lens is not directly on top, the aperture might not operate. 2. To remove, just turn it to the left. (counterclockwise) NOTES: (1) Do not press in the Depth of Field Button when changing lenses. (2) Avoid touching the lens glass and camera mirror with your fingers when changing lenses.

DEPTH OF FIELD

1. The smaller the aperture, the wider the depth of field and the larger the aperture, the narrower it becomes.

2. The longer the lens focal length, the narrower the depth of field and the shorter the focal length, the wider it becomes.

3. The farther the distance the lens is focused on, the wider the depth of field.

4. The zone of sharpness in front of the point of sharpest focus is narrower than the zone of sharpness behind the same point.

The colors of the ST801's depth of field indicator are matched with those of the aperture numbers to simplify checking of the depth of field. 4www.Butkus.org

4. In each case, the shutter speed is set at 1/60 sec. (marked with an X on the Shutter Speed Scale).

2. An FP-class bulb is used on the firing unit.

Flash guide number divided by subject-to-film distance equals aperture.

Example: Electronic Flash (Guide No. m18/ ft. 60) FUJICOLOR N100, FUJICHROME R100, FUJIPAN SS Subject-to-film distance=3m/10ft:

2. FP Flash Bulb

Since the flash guide number varies with the shutter speed, the recommended procedure for determining the aperture is to follow the instructions packed with the flash.
