NiSi JetMag Pro 82MAG 磁吸式後蓋

Finally, a back cap that actually clicks into place with a reassuring thud instead of feeling flimsy. The twist-lock mechanism is smooth and keeps my magnetic filters secure even when tossed in a bag.

Finally, a lens cap that actually stays put in my bag instead of popping off. The magnetic hold is strong enough that I don’t worry about it falling off mid-hike. Paired with the JetMag Pro system, swapping filters is genuinely quick.

The magnetic attachment is so satisfying—it clicks right on and stays put, no fumbling when I'm swapping filters in the field. This cap fits my JetMag Pro setup perfectly and keeps dust off the glass between shots.
