This NiSi Filter Holder 180 is specially designed for use with the Canon EF 11-24mm F/4L USM and 180 mm square filters. It lets you mount large square or rectangular filters on a super wide-angle lens and shift the filter to match your scene. The holder supports common landscape workflows where you need to balance bright skies and shaded foregrounds.
The holder is made from aviation-grade aluminum, CNC machined for precise tolerances. NiSi applies a matte black frosted finish to the surface to reduce reflections. In addition, the screw accessories are copper with black nickel plating for durability. Together these features help reduce stray light and maintain image quality.
Square and rectangular filter systems solve problems that screw-on round filters often cannot. For example, one square or rectangular filter can work with many different lens sizes when you use the appropriate adapter rings. This reduces the need to buy multiple screw-on filters.
Rectangular filters are also ideal when the horizon or any transition in a scene is off-center. You can shift the filter up or down in the holder to blend the transition into the composition. As a result, adjustments are often imperceptible in the final image.
Graduated rectangular filters come with different transition types. Soft-edge graduates work well with wide-angle lenses, while hard-edge graduates are recommended for normal and longer lenses.

Landscape photographers often use this holder with graduated neutral density filters to balance a bright sky against a darker foreground. Because the filter can move within the holder, you can place the transition precisely where it belongs in your composition. Also, if you shoot with different lens sizes, you can adapt the same filters to other lenses using adapter rings.
