Main Switch

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 I 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. * Do not touch the shutter curtain and DX contacts.

Engage the film perforations with the sprocket teeth and make sure the film lies flat and tight as shown in the illustration, then close the Camera Back. As soon as 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

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. * The display in the panel will run through quickly if you continue to push the lever for more than a second.4www.butkus.org * 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 or continuous auto focus pictures, set the lever to "AF". If you want to take trap focus or manual-focus pictures, set it to "MF".4www.butkus.org

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.4www.butkus.org

To obtain correct exposure change the aperture or shutter speed so that the mark "" appears, then shoot.

· If you use an AF Converter (optional accessory), take pictures in the "Av" or "M" mode. Even if the camera is set to other exposure modes, it will operate in the "Av" mode.

Shutter Release If the Shutter Release is depressed halfway, the lens is driven to focus itself (when the Selector Lever is set at "AF") and the shooting information at that time is shown in the viewfinder and display panel. It will stay for 8 seconds after the finger is released, and turn off. Then, depress the Shutter Release all the way to take your picture.

As soon as the flash has fired, the entire liquid crystal display in the viewfinder will illuminate in orange color to let you see that the flash has surely fired while you take pictures. If you are taking auto exposure pictures with the CS-1 10AF, the shutter speed is automatically set to 1/90 sec. If you are working in the manual exposure mode, the shutter will trip with the shutter speed you have set if it is 1/90 sec. or slower. If the CS-110AF is attached or detached with some types of lenses mounted on the camera (AF Zoom Lens 28-85 mm F3.5-4.5, for example), it may knock against the lens. In this case, dismount the lens before attaching of detaching the flash.
