Rear Mobile Lens Cap (All Series), M-Series

$1

Add a rear lens cap to your T-Series or M-Series lenses. The press-fit rear cap keeps the back opening of your Moment lens clean and safe, while the durable attachment leash keeps it close by.

For T-series thread the Rear Lens Cap leash through the molded anchor loop of your existing T-Series front lens cap. Pass the strap back through the leash slot to secure, similar to a luggage tag. Compatible with both I and II T-Series.

For M-Series simply adhere the Rear Lens Cap to the front of your existing M-Series front lens cap.

Please note that you must choose the Rear Lens Cap that corresponds to the series of your front lens cap.

Not compatible with O-Series lenses.

Moment Rear Lens Cap (M-Series) — a $1 fix for the thing you'll lose on the road

The gist: A tiny, cheap cap that keeps sand, dust, and pocket lint out of your Moment M-Series lens mount between shots — the kind of accessory that matters more once you're traveling than at home.

  • Press-fit design: Simply adheres to the front of your existing M-Series front lens cap, so both caps travel together instead of rattling loose in a bag.
  • Protects the mount: Keeps the exposed lens interface clean, which matters on dusty trails, beach shoots, or humid climates where grit can scratch glass.
  • Featherweight: Pack Hacker's gear database lists it at just 0.05 oz — effectively free to carry.
  • Budget insurance: At roughly $1, it's a rounding-error add-on next to a $99+ Moment lens.

Pack Hacker's travel gear database catalogs the M-Series rear cap's minimal weight and low price point, underscoring why it's an easy add for anyone already carrying Moment glass.

Best for: Nomads shooting content on the go who want to protect an M-Series lens mount without adding bulk. Skip it if: you shoot T-Series lenses instead — you'll need the T-Series-specific cap. Runs ~$1 — check the current price before buying.
