NiSi makes a very high-quality filter system that is well engineered. NiSi has a more premium feel than LEE, but their system can take a little more time to become intuitive to assemble. Both are great systems, but NiSi is responding to photographers needs faster than anyone else in filters today. You can order the new NiSi 150mm Filter Holder For Sony FE 12-24mm f/4 G at Amazon.
