PolarPro Helix MagLock 濾鏡專用 Helix 底座防護蓋

Finally, a cap that actually stays on securely when I toss the filter into my bag. The snug fit on the base plate gives me real peace of mind.

The magnet on this cap clicks into place with a satisfying snap, and it doubles as a front protector for my filters when I switch between setups. It’s a small thing, but having a dedicated cap that fits both roles means one less piece to lose in my bag.

After losing my original cap on a shoot, this replacement clicks on just as securely as the factory one and mates perfectly with the Base Plate. The threading is precise, so it spins on without any wobble. Glad to have the set complete again.
