Lens Cap Voigtlander 39 mm — front protective cap for 39mm lenses

Voigtlander 39 mm lens cap is a front protective cover designed to fit lenses with a 39 mm filter/thread size. It shields the front element from dust, fingerprints, scratches and light impacts during storage and transport. The cap offers a compact, low-profile fit that preserves optical surfaces when the lens is not attached to a camera, and it is compatible with lenses that accept a 39 mm screw-in or push-on cap.

Advantages

The cap provides reliable protection for the lens front without adding significant bulk or weight. Its secure fit reduces the risk of accidental detachment while in a bag, and the simple attachment and removal process makes it convenient for frequent use. Made to match the size and profile of 39 mm lenses, it minimizes light leakage and contact with the glass surface.

Suitable for

• Protecting 39 mm filter-thread lenses during storage
• Transporting compact lenses in camera bags or cases
• Keeping front elements clean during lens swaps or maintenance
• Use with vintage or modern lenses that accept 39 mm caps

Key specifications

• Fit: front cover for lenses with 39 mm filter/thread size
• Type: front protective lens cap
• Material: durable lightweight plastic (non-abrasive contact)
• Attachment: snap-on / screw-fit compatible with 39 mm threads
• Finish: matte exterior to reduce reflections

How to use

Align the cap with the lens front and press gently until it snaps into place or turns smoothly if using a screw-fit variant. To remove, hold the lens barrel firmly and pull the cap straight off or rotate counter-clockwise for screw-fit types. Ensure the lens surface is free of loose debris before attachment to avoid trapping particles between the cap and the glass.

Usage recommendations

Store the cap on the lens whenever the lens is not mounted on a camera to protect the front element. Clean the cap occasionally with a soft, dry cloth and avoid harsh chemicals. If the cap collects grit or sand, rinse it with clean water and dry thoroughly before reattaching to prevent abrasion.
