NiSi released a new JetMag Pro 49MAG magnetic filter system that locks (compatible with M, Q, and D-Lux lenses). The new system is a slim ring that lives on the camera; filters snap on magnetically, and a short twist locks them so they cannot be knocked off. Orders are now open at:

Leica Q series compatibility
If you shoot with a Leica Q3, Q3 43, or Q3 Monochrom, this system is completely plug-and-play. Because the Summilux and APO-Summicron lenses on the Q series already feature a native E49 thread, you simply screw on the slim 49mm-to-49MAG adapter ring once, and your camera is immediately integrated into the magnetic ecosystem.
Leica M-mount compatibility
While the system is named 49MAG, it’s actually fed by a series of five adapter rings. In addition to the native 49mm ring, NiSi offers adapters for 39mm, 40.5mm, 43mm, and 46mm threads. This means a single set of 49MAG glass can seamlessly serve an entire shelf of classic M-mount lenses.
The most common complaint with magnetic filters is that they walk off the front of your lens the second they catch on a strap or brush against a bag. The JetMag Pro system solves this with a patented locking mechanism. The filter snaps on magnetically, but a short, deliberate twist locks the internal handle. Once locked, it cannot be knocked off. It takes about one second to swap a filter with one hand, without taking your eye off the EVF.
The NiSi JetMag Pro 49MAG magnetic filters also work with the Leica D-Lux 8 43mm thread via the 43mm-49 MAG ring.
The 49MAG range includes all of NiSi’s premium glass options:
