3. Operation
3.1 Purpose and Usage
The ProMaster Body Cap serves as a protective cover for your camera's lens mount and sensor. It should be used whenever a lens is detached from the camera body, especially during storage, transport, or when changing lenses in dusty or humid environments. Consistent use helps to:
- Prevent Dust and Dirt: Keeps airborne particles from settling on the camera sensor, which can cause spots in images.
- Protect from Scratches: Shields the delicate lens mount and sensor from physical damage.
- Guard Against Moisture: Reduces the risk of moisture or humidity entering the camera body.

4. Care and Maintenance
4.1 Cleaning
To ensure optimal protection for your camera, keep the body cap clean. Wipe the exterior with a soft, dry, lint-free cloth. For the interior surface that faces the camera sensor, use a blower brush to remove any dust. Avoid using harsh chemicals or abrasive materials, as these can damage the cap or leave residues that could transfer to your camera.
4.2 Storage
When not in use, store the body cap in a clean, dry, and dust-free environment. Keeping it in a camera bag compartment or a sealed container can prevent it from accumulating dust that could later transfer to your camera's sensor.
5. Troubleshooting
5.1 Cap Does Not Attach Smoothly
- Check Alignment: Ensure the white index mark on the cap is perfectly aligned with the mark on the camera body before rotating.
- Verify Mount Type: Confirm that your camera is a Sony E-mount model. This body cap is specifically designed for Sony E-mount cameras.
- Inspect for Obstructions: Check both the camera mount and the cap for any debris or damage that might prevent proper attachment.
5.2 Dust Still Appears on Sensor
- Clean Cap Regularly: Ensure the interior of the body cap is clean before attaching it.
- Minimize Exposure: When changing lenses or attaching the cap, perform the action quickly and in a clean environment if possible.
- Professional Cleaning: If dust persists, your camera sensor may require professional cleaning.
