Operating the Camera
1. Power On/Off
The camera's protective front cover acts as the power switch. Slide the cover open to turn the camera on, and slide it closed to turn the camera off.
2. Zoom Operation
The IQ Zoom 90MC features a powerful 38-90mm zoom lens. Use the zoom buttons (typically marked 'W' for wide and 'T' for telephoto) to adjust the focal length. Zoom out for wide-angle shots (e.g., group photos, landscapes) and zoom in for close-ups.

3. Focusing and Exposure
The camera utilizes a passive five-point auto focus system to ensure sharp images. Its multipattern metering system accurately measures available light, even in challenging conditions, to provide properly exposed photographs. Simply press the shutter button halfway down to activate autofocus and metering, then press fully to take the picture.
4. Panorama Mode
For large group scenes or expansive landscapes, switch to panorama mode. This mode can be activated at any time or frame, allowing you to capture a wider field of view.
Maintenance
1. Cleaning
- Camera Body: Use a soft, dry cloth to wipe the camera body. For stubborn dirt, slightly dampen the cloth with water. Avoid using solvents or abrasive cleaners.
- Lens: Use a lens brush or a blower to remove dust. For smudges, use a specialized lens cleaning solution and a microfiber cloth. Do not touch the lens surface with your fingers.
2. Storage
When not in use, store the camera in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Camera does not power on. | Batteries are dead or incorrectly inserted. | Replace batteries with new CR2 batteries, ensuring correct polarity. Ensure the front cover is fully open. |
| Film does not advance. | Film not loaded correctly. | Open the back cover and re-load the film, ensuring the leader is properly engaged with the take-up spool. The fail-safe system should prevent most loading errors. |
| Photos are blurry. | Subject too close, camera shake, or focus issue. | Ensure subject is within the camera's focus range (macro focus range of 25 inches). Hold the camera steady or use a tripod. Allow the autofocus to lock before fully pressing the shutter. |
| Flash does not fire. | Flash mode is off or batteries are low. | Check flash mode settings on the LCD panel. Replace batteries if low. |
