NiSi JetMag Pro 77mm-82MAG Magnetic Adaptor Ring

This adaptor ring threads into a 77mm filter thread and converts it to the NiSi JetMag Pro 82MAG magnetic mount. Screw it in once and leave it there: from then on filters snap on and off in a second, which is the whole point of a magnetic system on a run-and-gun or video shoot.

• Magnetic mounting: Snaps NiSi JetMag Pro 82MAG magnetic filters onto a 77mm lens thread instantly — no cross-threading, no fumbling in the dark.
• Ultra-slim profile: The ring adds almost no stack height, so it will not introduce vignetting on wide lenses.
• Knurled edge: A textured outer edge gives grip for threading the ring on and off with cold or gloved hands.
• Aviation aluminium: CNC-machined aluminium with a matte anodised finish that will not flare into the frame.
• Build a one-filter kit: Standardise the whole lens kit on one filter size and stop buying duplicate filters per thread.
