LEE Filters FHSS 100mm Foundation Filter Holder System

Out on a windswept coastline at dawn, a landscape photographer needs to swap graduated ND filters quickly without losing the shot. The LEE Filters FHSS Foundation Holder System provides a rock-solid platform for 100mm square and rectangular filters, allowing you to stack ND and graduated filters with confidence. Its modular two-slot design accepts standard 2mm thick filters and rotates a full 360 degrees for precise positioning, while the high-grade composite and aluminum construction keeps weight down without sacrificing durability. Smooth, reliable performance with minimal vignetting, even on wide-angle lenses, makes this holder an essential tool for long exposures and precise filter alignment.
