Maintenance

Cleaning the Camera Body

Use a soft, lint-free cloth to wipe down the camera body. For stubborn dirt, a slightly damp cloth can be used, but avoid getting moisture into any openings.

Cleaning the Lens and Viewfinder

Use a lens brush or blower to remove dust. For smudges, use a specialized lens cleaning solution and a microfiber cloth. Never use abrasive materials.

Storage

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