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

Moment Rear Lens Cap (M-Series) — cheap protection for your content-creation kit

The gist: A $1 cap that keeps your Moment M-Series lens mount clean and scratch-free between filming sessions — useful if mobile video is part of how you build your professional brand.

• Press-fit design: Adheres to the front of your existing M-Series front cap so the two stay together in your desk drawer or camera pouch.
• Protects the investment: Keeps dust and desk debris out of the mount, which matters if you're using the lens for LinkedIn video, webinars, or portfolio content.
• Negligible weight: Pack Hacker's gear listing puts it at 0.05 oz, so it adds nothing to a commute bag or desk setup.
• Low cost: At about $1, it's a trivial add-on to protect gear you're already relying on for a professional look.

Pack Hacker's gear database documents the M-Series cap's minimal weight and price, which explains why it's a common no-brainer add for Moment lens owners.

Best for: Remote professionals who use a Moment M-Series lens for video calls or content and want to keep the gear scratch-free. Skip it if: you own T-Series lenses instead — that needs a different cap. Runs ~$1 — check the current price before buying.
