The Main Switch of this camera has three positions.
When it is set to LOCK, the camera is turned off.
When it is set to AK-L, you can take pictures with a
fixed exposure value on spot metering. When it is set
to ON you can take pictures by measuring exposure
on center-weighted metering. Set the switch
depending on the subject you want to shoot. If you are
not using the camera, always set it to LOCK.

LOCK The camera is turned off.

AE-L The camera is turned on and takes pictures on spot metering. If the Shutter Release is depressed
halfway, the AE lock is activated.

ON The camera is turned on and takes pictures on center-weighted metering. Normally, set the Main Switch
to ON.

* When the camera is turned on, the shutter speed, aperture and other information will be displayed for 8
seconds in the display panel and viewfinder.

Loading the Film

1. Set the Main Switch to ON, open the
Camera Back and load the film. To open the
Camera Back, push down the Camera Back Lock
while pressing in the button on it. To insert the
film, first fit the recessed end of the cassette to
the shaft located on top of the film chamber and
push it in. It will thus fit smoothly into position.
Always load and unload film in subdued light.

* If you use DX-coded film, the camera will
automatically set itself for the speed of the film
loaded in it.

you close it, the film will
automatically advance to
the first frame.

· If the film is advancing
properly, the Exposure
Counter will show "1" and
the Film Transport Mark "
       " will turn on in the
display panel. You are now
ready to take pictures. If
the Exposure Counter does
not move from "0" and
blinks, or if the mark "
       " does not turn on,
the film is not advancing
properly. Open the Camera
Back and load the film
correctly again.


Taking Pictures

Before taking pictures, set the drive mode,
focusing mode and exposure mode to the
desired positions according to the subject
you want to shoot.

To set the mode, move the Operating
Lever to the left or right while pressing
the corresponding mode button until the
desired mode appears in the display
panel.

www.butkus.us


* The display in the panel will run through
quickly if you continue to push the lever
for more than a second.

* The Program Reset Button is very useful
because the camera will automatically set
the positions of the drive mode, focusing
mode and exposure mode that are most
convenient for taking pictures as soon as
you press this button.

Mode description

* Drive modes There are three modes: single-frame shooting (S) continuous shooting (C), and self-timer

shooting (         ),


* Focusing modes There are four modes: auto-focus (AF), continuous autofocus CAF), trap focus (       ), and
manual focus (M).

* Exposure modes There are four modes: programmed auto exposure (PROGRAM), shutter-priority auto
exposure (TV), aperture priority auto exposure (AV), and manual exposure (M).

< Drive Modes >


                                Operating Lever to the right

(1) Single Frame Shooting: S Each time you depress the Shutter Release, the camera will expose one frame at
a time and advance the film to the next frame, then stop.

(2) Continuous Shooting: C While you are depressing the Shutter Release, the camera will take pictures one
after another at a rate of up to about 1.8 frames a second.

(3) Self timer Shooting: $) When you depress the Shutter Release, the self-timer LED in the camera front will
turn on and the shutter will trip after 10 seconds.

<Focusing Modes>

This camera offers a versatile focusing system
which consists of four focusing modes. The
auto-focus mode (AF) is convenient for taking
ordinary pictures. The continuous auto-focus
mode (CAP) allows you to take pictures in
succession by keeping your subject in sharp

focus as it moves. The trap focus mode       is
designed to trip the shutter as soon as the lens
is focused on the subject if you have set it to an
intended subject distance in advance. You can
also focus the lens manually (MF).

Selector Lever

This lever selects the basic focusing functions
of the camera. If you want to take auto-focus     Selector Lever at AF
or continuous auto focus pictures, set the lever

Auto Focus: AF



If you depress the Shutter Release
lightly the camera will automatically
start to focus the lens on the subject
located in the focusing frame in the
viewfinder. As soon as the green sharp-
focus LED turns on, you can depress
the Shutter Release all the way to take
your picture. This mode is convenient
for taking relatively static objects,
because the focus is locked when the
lens is focused on the subject by
depressing the Shutter Release halfway.

· If you take auto-focus pictures in the
drive mode "C" the camera will
automatically focus the lens for each
frame and take pictures continuously.





                                       Continuous Auto Focus: CAF As long as you keep depressing
                                                the Shutter Release lightly, the auto-focusing system will
                                               function and keep the subject in the focusing frame in sharp
                                                focus. This mode is useful for shooting moving subjects
                                               continuously, because it will continue to focus on the subject as
                                                the subject moves and its shooting distance changes, even after
                                                the lens has been once focused on it. Depress the Shutter
                                            Release all the way when the sharp-focus LED turns on.

                                                          · If you take continuous auto-focus pictures in the drive mode
                                             "C", the camera will automatically focus the lens on the subject
                                        and take pictures continuously with the fixed focus.

                                                          · Use the AF Lock Button to lock the focus.

Trap Focus:





This mode is useful for shooting nervous
animals or moving subjects at a fixed distance.
Face the camera toward the place where you
guess your subject will come, set the camera to
that distance with the Focusing Ring, attach the
cable switch and release it. As soon as the
subject comes to this distance and it is caught in
the focusing frame in the center of the
viewfinder, the shutter will trip to take your
picture.





Manual Focus: MF To focus, turn the Focusing Ring with your hand. If the subject is not correctly focused, the
front mix-focus or rear mix-focus mark will turn on. If it is in sharp focus, the green LED will turn on.

· When a mode Button (Focus Mode Button, Drive Mode Button etc.) is pressed. The display will appear for
eight seconds, then automatically turn off to save battery. However, the shutter speed and aperture you have set
will be stored in memory. The shutter speeds are displayed in 1/2-step increments from "2000" (1/2000 sec.) to
"16" (16 sec.), and the apertures In 1/2-step increments within the aperture range of the lens used. If the picture
is taken with an intermediate value between neighboring 1/2 steps, the camera will display the exposure value
that is most close to the value which is set. For example, if you are using an F1.8 lens, the camera will show
"1.7" if you are using an F3.3 lens, it will show "3.5".
· In the manual-exposure and shutter-priority auto exposure modes the shutter speeds can be set in 1-step
increments, and the apertures in 1/2-step increments. Intermediate setting is impossible.
· If the exposure mode is "PROGRAM", "Tv" or "Av", the lens' smallest-aperture value will blink when the
subject is overexposed relative to the correct exposure measured by the camera; and the maximum-aperture
value will blink if it is underexposed.

Using the Focus Lock


If you are taking auto-focus pictures and the subject you want to focus is not located in the center of
the viewfinder, or if the subject is difficult to focus in the situations mentioned below, use the focus
lock.

1. First, aim the Focusing Frame at your subject and focus. If the Shutter Release is depressed
halfway, the lens will start focusing itself. As soon as it is focused on the subject, the green LED
will turn on to tell you that focusing has been completed.
2. Lock the focus, recompose your picture and shoot.
* If you are shooting in the "AF" mode, the focus will remain locked while the subject is in sharp
focus and the Shutter Release is depressed halfway.

* If you are shooting in the "CAF" mode, lock the focus by pressing the AF Lock Button when the
subject is focused.

(The focus will remain locked as long as you keep your finger on the AF Lock Button.)





<Subjects That are Difficult to Focus>


In the following cases, the auto-focus system will not function properly and the "Focusing
Impossible" mark "=" will blink in the viewfinder. In such cases, focus the lens on another object
located nearly the same distance as the subject, activate the focus lock and shoot. You can also focus
the lens manually.

(1) When the subject is too bright or too dark;
(2) When the subject contrast is extremely low;
(3) When there is a strong light source in or around the Focusing Frame;
(4) When there are two or more subjects at extremely different distances in the Focusing Frame;
(5) When the subject has a uniform pattern such as vertical stripes
(6) Fast moving subjects;
(7) When the subject has no concrete form, such as flame or smoke;
(8) When the quantity of light from the subject is extremely reduced by an ND filter or polarizing
filter.

Program Control Diagram
This program control diagram shows the control range of shutter speeds and apertures relative to EV values in
the programmed auto exposure mode. The program lines mark the available ranges for wide angle, normal and
telephoto lenses, and these ranges are automatically set according to the focal length of the lens used. The
camera automatically chooses the optimum combination of shutter speed and aperture within the respective
program lines. However, you can also change the exposure within the range of the same EV value by shifting
the program lines by up to +3 steps. If the correct exposure that is set by the camera is F4, 1/125 sec., and you
want to shoot with a shutter speed of 1/60 sec., for example, shift the Operating Lever to the left by 2 steps.
Thus, an exposure value of F5.6, 1/60 sec. will be displayed and you can take a correctly exposed picture with
the same EV value.

· When the program is shifted, the program indicator will blink. After the picture is taken with the shifted
program or after the Main Switch is set to LOCK, the camera will automatically reset the exposure value that
was set before the program was shifted.

· This diagram shows the automatic control range with an F1.8 lens. In the case of lenses with different F
numbers, the control range becomes narrower as the lens speed decreases. The control range with an F2.8 lens,
for example, is represented by the dotted line in the diagram.



Automatic Exposure Compensation in the Mode

If the camera cannot provide a correct aperture for the shutter speed you have set in the shutter-priority auto
exposure mode, it will automatically choose again a shutter speed as close as possible to that which you have set
so as to provide correct exposure. Therefore even if the shutter speed which is displayed when the Shutter
Release is depressed halfway is different from that which you have set, you can go ahead and shoot if the
smallest-aperture value or maximum-aperture value does not blink. Likewise, in the aperture-priority auto
exposure mode, even if the displayed aperture is different from that which you have set, you can go ahead and
shoot unless the smallest-aperture value or maximum-aperture value blinks.
