Introduction
Thank you for choosing the K&F CONCEPT Magnetic Metal Lens Cap. This innovative 2-in-1 lens cap is designed to provide superior protection for your camera lens and filters. It features both magnetic and traditional thread-based attachment methods, ensuring quick and secure installation. This manual provides essential information on how to properly install, use, and maintain your lens cap.

Setup and Installation
The K&F CONCEPT Magnetic Metal Lens Cap offers two primary methods for attachment: magnetic and thread-based. It is crucial to note that the magnetic function is exclusively compatible with K&F CONCEPT magnetic filters.
Magnetic Attachment (for K&F CONCEPT Magnetic Filters)
- Ensure your camera lens is equipped with a K&F CONCEPT magnetic filter.
- Align the magnetic lens cap with the front of the magnetic filter.
- The cap will snap into place securely due to the magnetic connection. This method allows for quick installation and removal, preventing scratches to your lens filter.

Thread-Based Attachment (for standard threaded filters/lenses)
- If not using a K&F CONCEPT magnetic filter, the cap can be screwed onto any lens or filter with a matching thread size.
- Carefully align the threads of the lens cap with the threads on your lens or filter.
- Rotate the cap clockwise until it is securely fastened. Do not overtighten.


Operating the Lens Cap
The primary function of this lens cap is to protect your camera lens and any attached filters from dust, scratches, and impacts when not in use or during transport.
- Protection: When the cap is installed, it forms a robust barrier against external elements, safeguarding the delicate glass of your lens and filters.
- Quick Access: The magnetic attachment allows for rapid removal and re-attachment, ensuring you don't miss a shot while fumbling with traditional caps.


Maintenance
To ensure the longevity and optimal performance of your K&F CONCEPT Magnetic Metal Lens Cap, follow these maintenance guidelines:
- Cleaning: Wipe the cap with a soft, dry cloth to remove dust and fingerprints. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid abrasive cleaners or solvents.
- Storage: Store the lens cap in a clean, dry environment when not in use.
- Material: The cap is made of aviation-grade aluminum alloy, providing durability and effective protection.

Troubleshooting
- Problem: Magnetic attachment does not work.
- Solution: The magnetic function of this lens cap is specifically designed for K&F CONCEPT magnetic filters. If you are using a filter from another brand or a non-magnetic filter, the magnetic attachment will not function. In such cases, use the thread-based attachment method.
- Problem: Lens cap does not fit the lens/filter.
- Solution: Ensure you have selected the correct size lens cap for your lens or filter. The K&F CONCEPT Magnetic Metal Lens Cap is available in various sizes (e.g., 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm, 86mm, 95mm). Check the diameter marking on your lens or filter and compare it with the cap's size.
