The JJC 34mm lens cap (model SB1915) is a front protective cover designed for lenses with a 34 mm outer diameter or compatible 34 mm threaded filters.

The cap is lightweight and easy to attach or remove, offering a simple protective solution for routine storage and transport of compact lenses and filters.

Advantages

Its fitted design ensures secure placement on 34 mm threaded mounts or around a 34 mm outer diameter, minimizing the risk of accidental detachment. The cap is made from durable yet lightweight material that resists everyday wear and helps preserve optical performance by keeping the front element clean.

• Storage and transport in camera bags or pockets
• Protecting lenses during lens swaps or field use

Key specifications

How to use

Align the cap with the lens front or with a 34 mm threaded filter and press gently until it seats securely.

Regularly clean the cap interior and the lens front with a soft, lint-free cloth to prevent trapped debris from scratching the glass.
