Maintenance
Cleaning the Camera and Lens
Regular cleaning helps maintain the performance and longevity of your camera.
- Camera Body: Use a soft, lint-free cloth to wipe the camera body. For stubborn dirt, slightly dampen the cloth with water. Avoid using solvents.
- Lens: Use a lens brush or blower to remove dust from the lens surface. For smudges, use a specialized lens cleaning solution and a microfiber cloth. Never touch the lens surface with your fingers.
- Sensor: If dust appears on images, use the camera's sensor cleaning function. For persistent dust, consult a professional service center.
Battery Care
- Store batteries in a cool, dry place when not in use.
- Avoid fully discharging the battery frequently, as this can reduce its lifespan.
- If storing for extended periods, charge the battery to about 50% capacity.
Weather Sealing Care
The OM-1 boasts an IP53 weather-sealed design, making it dustproof, splashproof, and freezeproof. To maintain this protection:
- Ensure all port covers, battery compartment, and memory card slot covers are securely closed before exposing the camera to adverse conditions.
- After use in wet or dusty environments, wipe the camera clean with a dry, soft cloth.
- Avoid exposing the camera to extreme temperature changes rapidly, which can cause condensation.

The OM-1's robust IP53 weather sealing allows for operation in challenging environmental conditions.
