The Haida 150 Filter Holder for Sigma 14-24mm f/2.8 Art Lens is designed to enable the use of 150mm square filters on the ultra-wide Sigma Art lens without causing mechanical vignetting. It provides a stable mounting solution for landscape, architecture, and long-exposure photography.

Constructed from precision-machined aluminum alloy, the holder offers durability, secure filter installation, and compatibility with Haida 150 Series filters. It is ideal for photographers who require ND, graduated ND, or other creative filters while maintaining image quality across the frame.
