The new Lee Filters SW150 MK II filter system compatible with the Nikon 14-24mm f/2.8 lens will be released in a month. The new version 2 has a light shield and option for Big Stopper and Square Polarizer. It also fits the new Sigma 24mm f/1.4 lens.
Lee Filter are also currently testing a version two of their SW150 system on the Canon 11-24mm f/4 lens that will probably be announced soon.
