LEE Filters 100LEK 100mm Foundation Kit Filter Holder with 77mm and 82mm Adapter Rings

The LEE Filters 100LEK 100mm Foundation Kit is a modular filter holder system that delivers rock-solid stability for square and rectangular filters in landscape, architectural, and long exposure photography. Precision-machined from high-grade aluminum, it holds 100mm wide filters with two slots as standard, expanding to three for stacking graduated NDs, solid NDs, and polarizers without vignetting on wide-angle lenses.

The included 77mm and 82mm adapter rings ensure compatibility with a wide range of lenses, while the screw-in design guarantees a secure, wobble-free mount. A dedicated pouch protects the holder and rings during transport.
