NiSi JetMag Pro 82MAG Magnetischer Rückdeckel

Finally, a back cap that actually stays on without wiggling loose in my bag. The magnetic connection is strong enough that I can swap lenses without worrying about it falling off.

I was relieved to find a back cap that clicks on securely without any wobble, and the thin profile makes it easy to slide the filter into my pouch without adding bulk. Finally, no more worrying about scratching the rear element during a hike, and it keeps dust off between shots.

The magnetic snap is incredibly satisfying and holds the back cap securely every time, which gives me peace of mind when swapping filters in the field. It's a small detail, but it makes a big difference in keeping my kit clean and protected.
