Spare Front Lens Cap - Tele 58mm + Wide 18mm + Macro 75mm, M-Series

Moment M-Series Front Lens Cap — a cheap backup for your original Moment lens mount

The gist: A replacement front lens cap machined to fit Moment's original M-Series mobile lens mount, worth stashing a spare of if you still shoot with M-Series glass on the road.

• Machined to fit snugly: Moment builds this cap specifically for the M-Series mount, so it seats securely rather than a generic universal cap that can pop off in a bag.
• Protects the front element on the move: Shields the lens glass from scratches, dust, and drops — the kind of damage that happens fast when gear gets tossed into a daypack between stops.
• Cheap insurance for older gear: M-Series lenses are Moment's earlier mount system, and this replacement cap keeps still-functional lenses protected without buying new equipment.
• Small and packable: Light enough that carrying two or three spares in a lens pouch costs you nothing in space or weight.

Moment's own product listing describes the M-Series front cap as machined to fit snugly over the lens front, protecting it from "drops, scratches, dust, and the occasional tumble" while traveling.

Best for: travelers still using Moment's original M-Series lens mount who want a spare cap. Skip it if: your lenses are the newer T-Series mount — this cap won't fit them. Runs ~$1-5 — check the current price before buying.
