O-Series Front Lens Cap - 18mm Wide, Fisheye 15mm, Tele 60mm, Macro

Moment O-Series Front Lens Cap — Scratch-Free Lenses Wherever You Land

The gist: A snap-on front cap for Moment’s original O-Series lenses that protects your glass investment from scratches, dust, and drops while packed into a travel bag or kit.

• Fits Fisheye 15mm, Tele 60mm, and Macro O-Series lenses: A single cap design works across Moment’s original lens lineup — one spare covers your whole O-Series kit.
• Protects coated front element: O-Series lenses use multi-layer glass coatings that a stray scratch can permanently degrade — the cap blocks dust, sand, and impact before it reaches the glass.
• Snap-on retention: Stays securely seated in a packed bag, jacket pocket, or lens pouch during transit, removing cleanly when you’re ready to shoot.
• Compact replacement or spare: New O-Series lenses ship with a cap; this is a direct replacement if the original is lost, or a spare to keep on whichever lens isn’t mounted.

Moment’s product page confirms the O-Series front cap fits the Macro, Fisheye 15mm, and Tele 60mm lenses, designed as a protective replacement for the cap included with new O-Series lens purchases.

Best for: O-Series Moment lens owners who need a replacement cap or want spares to protect unmounted lenses during travel. Skip it if: your Moment lenses are T-Series or M-Series — Moment makes separate caps for those series. Runs ~$1 — check the current price before buying.
