5. Maintenance
5.1. Cleaning the Camera Body
Wipe the camera body with a soft, dry cloth. For stubborn dirt, use a cloth lightly dampened with water and then wipe dry. Avoid using organic solvents like alcohol or paint thinner.
5.2. Cleaning the Lens and Sensor
Use a blower brush to remove dust from the lens surface. For smudges, use a lens cleaning solution and a microfiber cloth. For sensor cleaning, it is recommended to consult a professional service or refer to advanced sections of the full user manual.
5.3. Battery Care
Always use the original Sony battery and charger. Store batteries in a cool, dry place. Do not expose batteries to extreme temperatures or disassemble them.
5.4. Storage
When not in use for extended periods, remove the battery and memory card. Store the camera in a cool, dry, and dust-free environment, preferably in a camera bag with desiccant packets to prevent mold and mildew.
6. Troubleshooting
- Camera does not power on: Ensure the battery is fully charged and correctly inserted. Check if the battery contacts are clean.
- Images are blurry: Check focus mode (AF/MF). Ensure sufficient lighting. Use a higher shutter speed or tripod if necessary. Verify image stabilization is active.
- Memory card error: Ensure the memory card is inserted correctly. Try formatting the card (this will erase all data). If the issue persists, try a different memory card.
- Flash does not fire: Check flash settings. Ensure the flash is raised. Some shooting modes may disable the flash.
- LCD screen is blank: Check if the display is turned off or if the camera is in viewfinder mode.
