NiSi V6/V7 Protection Lens Cap

Finally, a cap that snaps on securely and fits flush against the adapter ring — no more worrying about it popping off in my bag. The precise fit really protects the threads when the filter holder is off.

After fumbling with loose caps for months, this one stays securely attached to the adapter ring even when jostled in my bag. It’s a simple accessory, but the snug fit gives me total peace of mind when the filter holder isn’t mounted.

I was a little worried about losing the adapter ring when the filter holder is off, but this cap clicks on snugly and stays put. It's exactly what I needed to keep dust off the ring between shoots.
