Camera Care and Precautions
1. Handling, Cleaning and Storage
This camera is a high-precision instrument. Be careful not to drop it or subject it to shock. The Canon EOS-1 N has been designed for increased resistance to moisture. However, this camera is not waterproof and must therefore be handled with reasonable care. Keep the camera out of salt spray and protect it from excessive moisture. If used at the beach, clean it thoroughly afterward with a dry cloth. If dropped in water, contact an authorized Canon service facility. This camera contains high-precision circuits. Do not attempt to disassemble the camera yourself. Always take it to an authorized Canon service facility for repair. Do not touch the cameras electronic contacts with your fingers. Touching the contacts can cause corrosion and affect proper camera operation. After removing a lens from the camera, place it face down on a flat surface to avoid damaging the electronic contacts on the lens mount. Condensation is a problem when bringing cold equipment into a warm place. If the autofocus optics cloud over, accuracy may be seriously affected. Before entering a warm place, put equipment in a plastic bag so condensation forms on the outside of the bag. To remove dust from the lens, viewfinder eyepiece, mirror, focusing screen or film chamber, gently blow the dust away using a commercially-available bulbtype blower. Avoid directly touching any of these surfaces. Do not wipe the camera body or lens with any type of cleaner containing organic solvents. When further cleaning is necessary, consult your nearest Canon service center. The shutter curtain operates with extremely high precision and can be easily damaged if touched. When loading or unloading film, be careful not to touch the shutter curtain accidentally with your finger or the tip of the film. To remove dust from the shutter curtain or surrounding area, only use a blower and be careful not to blow air onto the curtain too strongly. Strongly blowing air onto the curtain may deform or damage it. Aerosol spray dust removers are not recommended for the shutter curtain. When storing the camera, wrap it in a clean, soft cloth and place it in a wellventilated, cool, dry, dust-free place. Be sure to keep the camera out of direct sunlight, and away from hot spots such as the trunk or rear window shelf of a car. Avoid places where moth balls are used, and in extreme humidity, use a desiccant. To prevent corrosion, avoid storing the camera in a laboratory or other location where chemicals are used. Also, do not store the camera in a drawer or other non-ventilated place. Remove the battery if you do not expect to use the camera for about three weeks or longer. It is also recommended to take the camera out and release the shutter occasionally to prevent build up of mold or corrosion.

This section explains the preparations necessary to set up the camera before use, as well as the basic operation of the camera.
Attaching the Strap Thread the ends of the strap through the strap fixtures as shown. Pull firmly on the strap to make sure it is held securely by the buckles.

1. Loading the Battery

This camera operates on a 6-volt, 2CR5 lithium battery, housed in the grip.
Refer to page 93 for additional information on the batteries of the EOS-1 N DP model and page 96 for the EOS-1 N HS model and the EOS-1 N RS model.

If the in-focus indicator blinks, the autofocus system cannot focus the subject and the shutter will not release. Refer to 4. Manual Focusing on page 36 for instructions on how to focus the subject manually. Exposure settings are displayed in the LCD panel and viewfinder.

[Exposure Warnings]
If a shutter speed of 30 and the maximum aperture value blink in the display, the subject is too dark. Switch to flash photography, referring to V. Using Flash on page 76.
If a shutter speed of 8000 and the minimum aperture value blink in the display, the subject is too bright. Attach a neutral density (ND) filter to the lens.
Six-Second Timer When you release the shutter button after pressing it halfway, the LCD panel and viewfinder displays remain active for six seconds. Program Shift Function When taking pictures in Program AE mode, you can shift the program to change the set shutter speed and aperture value combination while maintaining the same exposure. After pressing the shutter button halfway, turn the main dial until the desired shutter speed/aperture value combination is displayed. Remaining Frame Counter When nine frames or less remain on the roll, the number of remaining frames is displayed in the viewfinder below the exposure level display. F indicates that 10 or more frames remain on the roll. When less than 10 frames remain, the display counts down the frames in descending order: 9, 8. 2, 1.
Non-DX films are identified as 36-exposure rolls, and the remaining frame counter operates accordingly.

Remaining frame counter

This cameras wide-zone autofocus system lets you freely select from five focusing points, allowing you to keep the scene composed as desired while concentrating on the subject. Also, a rich selection of exposure options lets you select the metering mode appropriate for the subject or shooting situation, and flexible exposure compensation capabilities let you fine tune the exposure in real time.
First make sure the camera's main switch is set to A or

have vertical sensors, focus the subject, then recompose the picture using the focus lock function. 3) In the case of (f), use the center focusing point which has a horizontal sensor, focus the subject, then recompose the picture using the focus lock function. 4) Set the lens focus mode switch to M and manually focus the subject. See 4. Manual Focusing on page 36 for manual focusing instructions.

4. Manual Focusing

Use manual focusing when the subject is difficult to focus with the cameras autofocus system, or when you need to control the focus for alternative focus effects.
1 Set the lens focus mode switch to M.
The AF mode display is extinguished in the LCD panel.

CA NO N

Full-time Manual Focusing with USM (Ultrasonic Motor) Lenses USM lenses are equipped with a full-time manual focusing function that lets you immediately manually adjust the focus after autofocusing is completed to achieve the desired effect. Use this function in One-shot AF mode.
This method of focus adjustment cannot be used if your USM lens does not have a distance scale.

L EN S

When using a USM lens equipped with an electronic manual focusing system, setting this custom function will allow manual focusing only when the lens focus mode switch is set to M.
5. Selecting the Metering Mode
Three metering modes are available: evaluative metering ( ), partial metering ( ) and fine spot metering ( ). Center-weighted average metering as well as spot metering linked to the focusing points can also be set with the corresponding custom function. In all metering modes, pressing the shutter button halfway activates the built-in metering system and determines the exposure. Whether outdoors, indoors, at the sea or in the mountains, there is an infinite number of lighting conditions and subject types. Select the metering mode best suited for each subject. mode 1 While pressing the meteringthe left selector, turn the main dial to
or right until the desired metering mode indicator appears in the LCD panel.
The metering mode changes in the cyclical sequence shown above.

Metering mode indicator

2 Release the metering mode selector.
Selecting the Metering Mode

Evaluative Metering ( )

Use this mode for general subjects and backlit scenes. By dividing the viewfinder into 16 metering zones linked with the five focusing points, the camera evaluates factors such as subject size, position (based on the focusing point in use), brightness, background, front lighting and back lighting to determine the best exposure setting. In manual focusing mode, evaluative metering is based on the central focusing point.

When the subject is lit by strong backlighting or a narrow beam of light such as a spotlight, we recommend using partial metering ( ) or fine spot metering ( ).
This function lets you select center-weighted average metering instead of evaluative metering ( ). Partial Metering ( )
This mode limits the metering area to the central part of the viewfinder (approx. 9% of the image area). Select this mode when the subject is backlit or positioned near a strong light source.

Fine Spot Metering ( )

This mode limits the metering area to the center of the viewfinder as defined by the fine spot metering mark (approx. 2.3% of the image area). Use this mode when you need an accurate exposure reading of a specific subject area.
In continuous shooting mode ( ) or high - speed continuous shooting mode with the Power Drive Booster E1 ( , ), the exposure value determined for the first frame is also used for the second and consecutive exposures.
This function lets you select spot metering linked to the focusing points. Metering is limited to the area of the manually selected focusing point (approx. 3.5% of the viewfinder image area).
In One-shot AF mode, exposure setting is locked during continuous shooting, but the AE lock indicator does not light in the viewfinder.

6. AE Lock

The EOS-1 N's evaluative metering system is coupled to the five focusing points. It controls the exposure according to the subject's position, based on the focusing point in use. If you want to determine the exposure independently from the focusing operation, use AE lock. Use it when you also want to change the composition of the picture after determining the exposure. AE lock is effective for backlit subjects and other situations where there is extremely strong contrast between the subject and background. that you want to 1 Focus the subjectcameras metering measure with the system.
The exposure values are displayed in the viewfinder and LCD panel.
2 Press the AE lock button (
lights in the viewfinder to indicate that the AE lock is set. When you release the AE lock button ( ), the metering timer is activated and the exposure remains locked for six seconds. Pressing the AE lock button ( ) again renews the locked exposure setting. AE lock is canceled six seconds after the AE lock indicator ( ) lights in the view finder display, or whenever you press the AF mode selector, metering mode selector, shooting mode selector or focusing point selector.
To accurately meter a specific subject area with the AE lock function, we recommend using partial metering or fine spot metering. Place the subject in the center of the viewfinder when activating AE lock.

The optionally available Command Back E1 does not have a quick control dial. When using this command back, set the exposure compensation by turning the main dial while pressing the exposure compensation button.
8. Auto Exposure Bracketing [AEB]
Use auto exposure bracketing to take a sequence of pictures at different exposures. When this function is set, the camera automatically takes three exposures in sequence while shifting the exposure for each picture. The bracketing amount can be set in 1/3-stop increments up to 3 stops from the metered exposure value. When the shutter button is pressed, three frames are exposed according to the current film winding mode (refer to 2. Changing the Film Winding Mode on page 67), in the sequence: underexposure correct (metered) exposure overexposure. Auto exposure bracketing is particularly effective when using slide film, which produces noticeably different results with even small exposure variations.

Underexposure (1/3)

Correct (metered) exposure (0)

Overexposure (+1/3)

The AEB step amount can also be input in 1/2-stop increments. The shooting sequence can be changed to: correct (metered) exposure underexposure overexposure. This function also lets you set the AEB step amount by simultaneously pressing the AF mode and shooting mode selectors while turning the main dial.
If auto exposure bracketing is used with custom function F-12 set to mirror-up mode, the camera will operate in single exposure mode regardless of the current film winding mode (single exposure, continuous exposure).
Auto Exposure Bracketing [AEB]

If the camera sets a slow shutter speed, use a tripod to prevent camera shake. To cancel Depth-of-Field AE in mid-operation, press the focusing point selector, the shooting mode selector, the AF mode selector or the metering mode selector.
For greater depth of field, we recommend using a wide-angle lens. For shallow depth of field, place both points 1 and 2 on the same point. This method is effective for blurring the foreground and background when shooting portraits. Use a telephoto lens for best effect.

4. Manual Exposure [M]

This mode lets you set both the shutter speed and aperture. Use this mode when you need complete control of exposure for creative effects or when using a hand-held exposure meter. The main dial sets the shutter speed and the quick control dial sets the aperture. Using the Cameras Built-in Meter
selector, turn the main dial to the left or right until M appears in the LCD panel.

The optionally available Command Back E1 is not equipped with a quick control dial. When using the Command Back E1, set the aperture by pressing the exposure compensation button and turning the main dial.

Manual Exposure [M]

5 Press the shutter button halfway to
focus the subject. M and the exposure values are displayed in the viewfinder. The exposure level indicator at the right of the viewfinder shows how far the current exposure setting is from the exposure value metered by the camera.
The indicator shows that the set exposure will be one stop over the metered exposure.
6 Set the shutter speed and aperture
value as desired while watching the exposure level display, then press the shutter button completely to take the picture.
This custom function lets you switch the functions of the main dial and quick control dial. In addition to 1/3-stop increments, shutter speeds and aperture values can also be input in 1-stop or 1/2-stop increments. This function lets you set the aperture value using the focusing point select button ( ) in combination with the main dial.

The operation method described in step 4 can be changed in six different ways using various combinations of custom functions 5 and 11 (refer to page 92).

5. Bulb Exposure [

The shutter stays open for as long as you press the shutter button. By connecting the optional Remote Switch 60T3 to the cameras remote control socket, you can keep the shutter open without holding the shutter button pressed. Use this mode when long exposures are required, such as for pictures of night scenes and fireworks displays. pressi g e hoo ing 1 W h i l e selector,nturnt hthe smain tdial mode until panel.

Bulb Exposure [

In bulb exposure mode, the LCD panels frame counter display counts the elapsed time from when the shutter was released, starting over every 30 seconds. One battery check bar ( ) appears on the display after every 30 seconds, allowing time measurement up to 120 seconds using all three bars.
This display example shows elapsed time of 120 seconds This cameras bulb exposure operation is designed to consume very little power, realizing virtually no drain on the battery. LCD panel illumination is turned off during bulb exposure operation.
Optional accessory Command Back E1 features a long-release timer for timed exposures up to 23 hours, 59 minutes, 59 seconds, adjustable in 1-second increments.

6. Multiple Exposures [

The manually-set film speed is automatically canceled when new DX-coded film is loaded.
This custom function can be used to prevent the camera from automatically setting the film speed according to the films DX code. When this function is set, the camera does not change the manually set film speed when changing film, handy when using many rolls of the same type of film in succession.
2. Changing the Film Winding Mode
Two film winding modes are available: single exposure mode and continuous exposure mode. Single Exposure ( )
The film advances one frame after each picture is taken. After taking a picture, return the shutter button to the half-pressed position to prepare for the next exposure while keeping the exposure value locked (possible only when camera is set to One-shot AF and evaluative metering mode).

Continuous Exposure (

Pictures are taken continuously at a rate of approx. 3 frames per second as long as the shutter button is held pressed.
Attaching the optional Power Drive Booster E1 provides the following two continuous exposure modes:
High-Speed Continuous Exposure (

Film Winding Automatic Gear Switching Function
If film winding becomes an excessive burden to the camera due to a sharp drop in battery capacity (which can occur when shooting in a cold environment), the film winding system automatically switches gears to reduce the winding speed and minimize battery drain. When this occurs, one of the film winding mode indicators ( ) blinks in the LCD panel. To cancel this function and return to normal-speed winding, open the palm door and press the < > button and < > button simultaneously or when you replace the film or battery. When the camera automatically switches to reduced-speed winding, check the battery level (see page 15) and replace the battery or prepare a new battery as indicated. When film winding or rewinding stops in mid-operation, the indicator blinks in the LCD panel. When the battery is replaced with a new one, film winding continues automatically. If the camera stopped in the middle of rewinding, press the film rewind button ( ) to continue the rewinding operation. Do not dispose of the battery if its capacity drops due to cold shooting conditions. Its capacity may return when it returns to normal temperature.

Maximum Continuous Shooting Speed in Different AF Modes (frames/sec.) Continuous exposure ( ) One-shot/Manual approx. 3 fps AI Servo approx. 2.5 fps
Refer to page 97 for the maximum shooting speeds in different AF modes with Power Drive Booster E1.
3. Changing the Film Rewinding Mode
In normal operation at the end of the roll, the camera automatically rewinds the film at high speed and winds the film leader completely into the cartridge. Using custom functions F-1 and F-2, however, you can change the cameras film rewinding operation as described below:
Custom Function Nos. F-1 and F-2 can be used in combination. For instructions on how to change the custom function settings, see 1. Setting and Resetting Custom Functions on page 82.
