Enjoy quickly swapping filters with the JetMagPro Magnetic Adapter Kit from NiSi. This kit features an adapter ring for lenses with 72 threads for compatibility with NiSi's magnetic 82MAG filters as well as a magnetic front lens cap to complete the system.
This 72-82mm JetMag Pro Magnetic Adapter Ring from NiSi is designed for use with their JetMag Pro magnetic filter system. Once screwed onto the 72mm front thread of your lens, this adapter allows you to magnetically attach the 82mm filters of the JetMag Pro system. This means you can swap filters quickly on the go to suit your needs or create your desired look. Its aluminum construction makes it highly durable, and the slim design prevents vignetting in your images.
The JetMag Pro 82MAG Magnetic Front Cap from NiSi is designed specifically for their JetMag Pro line of magnetic filters. This cap magnetically locks to the front of your filter, protecting it from dust, scratches, and moisture during storage or transport. Similarly, it allows you to keep your magnetic adapter ring attached to the front of your lens, saving you the time of screwing it on once you're ready to shoot. Just quickly swap the magnetic cap with one of the filters and you're ready to shoot. Its aluminum construction is both lightweight and durable for easy and safe carrying.
