3. Operating the Camera

3.1 Power On/Off

Locate the power switch, typically near the shutter release button. Slide it to the 'ON' position to power on the camera. Slide to 'OFF' when not in use to conserve battery life.

3.2 Autofocus System

The N70 features an advanced autofocus system with a cross-type sensor module, offering an extra-wide focus detection area. It can detect subjects in low light conditions (as dim as EV -1 at ISO 100). The camera supports both spot and wide-area autofocus modes. Use the AF/M switch on the lens or camera body to select between autofocus and manual focus.

3.3 Exposure Modes

The N70 offers a variety of exposure modes:

• Program (P) Mode: The camera automatically sets both shutter speed and aperture.
• Flexible Program (P_F) Mode: Allows shifting the shutter speed and aperture combination while maintaining optimal exposure.
• Shutter-Priority Auto (S) Mode: You set the shutter speed, and the camera selects the appropriate aperture.
• Aperture-Priority Auto (A) Mode: You set the aperture, and the camera selects the appropriate shutter speed.
• Manual (M) Mode: You control both shutter speed and aperture.
• Bracketing: Allows taking multiple shots at different exposures.

The 3-D matrix metering system uses an 8-segment SPD sensor to analyze scene brightness and contrast for accurate exposure calculation.

3.4 Built-in Flash Operation

The N70 includes a built-in pop-up TTL flash. When required, the flash will automatically deploy or can be manually activated depending on the selected exposure mode. The five-segment TTL multi-sensor ensures optimal flash balance for various lighting conditions.

3.5 Film Rewind

Once the entire roll of film has been exposed, the camera will automatically rewind the film back into its cassette. Ensure the rewind process is complete before opening the camera back.

4. Maintenance

4.1 Cleaning the Camera Body and Lens

• Use a soft, lint-free cloth to wipe the camera body. For stubborn dirt, slightly dampen the cloth with water.
• For the lens, use a lens brush or blower to remove dust. Follow with a lens cleaning solution and a microfiber cloth, wiping gently in a circular motion from the center outwards.
• Avoid using harsh chemicals or abrasive materials.

4.2 Storage

Store the camera in a cool, dry place away from direct sunlight, high humidity, and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.

5. Troubleshooting

• Camera does not power on: Check battery installation and ensure batteries are fresh.
• Autofocus not working: Ensure the AF/M switch is set to 'AF'. Check for sufficient light and contrast in the subject.
• Exposure issues (too dark/bright): Verify the selected exposure mode and settings. Ensure the metering area is appropriate for the scene.
• Film not advancing/rewinding: Check if film is correctly loaded and if the camera back is securely closed. Ensure there is enough battery power.
• Unusual color casts in developed photos: This can sometimes be related to film type, processing, or specific camera unit characteristics. If persistent, consult a professional camera technician.
