Moment Rear Lens Cap (T-Series I & II) — keeps your lens mount clean, once you get it on

The gist: A leashed rear cap that protects your T-Series lens mount from dust and grit on the road — worth the one-time fiddly install.

  • Leash-and-loop attachment: Threads through the molded anchor loop on your existing T-Series front cap, then loops back through its own slot like a luggage tag, so it can't fall out of your bag.
  • Compatible with both generations: Works with T-Series I and II front caps, so it travels with you if you upgrade lenses.
  • Protects the mount: Shields the lens interface from sand, dust, and moisture between shots — a real concern on beach or jungle trips.
  • Low cost, high protection ratio: At around $10, it's cheap insurance for lenses that run $99+.

Buyer feedback collected on Amazon's product listing for the T-Series cap flags the leash-through-loop assembly as fiddly the first time, though functional once attached.

Best for: Frequent travelers with T-Series glass who want mount protection between shoots. Skip it if: you'd rather skip the initial assembly hassle — budget 5 minutes to thread it correctly the first time. Runs ~$10 — check the current price before buying.
