Lens cap Calumet 55mm — protective front cap for 55 mm lenses

Calumet Lens Cap 55mm is a front protective cap designed to fit lenses with a 55 mm diameter. It protects the front element from dust, moisture and scratches when the lens is not mounted on a camera. The cap is suitable for use during storage and transport and provides a simple, reliable cover for lenses with a 55 mm threaded or snap-on front.

Advantages

The cap offers a compact, lightweight design that does not add bulk to your kit. Its secure fit prevents accidental detachment while remaining easy to remove when you need to shoot. The material resists everyday wear and provides basic protection against contaminants and minor impacts without interfering with lens filters or accessories when removed.

Suitable for

• Lenses with a 55 mm front diameter
• Storage of spare lenses in bags or cases
• Transport of lenses to shoots or events
• Quick protection between lens changes

Key specifications

• Front diameter compatibility: 55 mm
• Type: front lens cap (snap-on or threaded, depending on lens front)
• Material: durable plastic construction
• Weight: lightweight design for minimal added mass
• Finish: matte surface to minimise reflections

How to use

Align the cap with the lens front and press gently until it snaps into place or threads securely, depending on the lens mounting style. To remove, pinch the cap’s grip points (if present) or rotate gently to unthread, then pull away from the lens. Inspect the cap for dust or grit before fitting to avoid transferring particles to the lens surface.

Usage recommendations

Store the lens cap fitted during transport and when lenses are kept in bags or cases. Clean the cap periodically with a soft cloth to remove dust. For longer-term storage, keep a lens cloth between cap and lens if moisture control is required.
