Utilizing a modular, snap-on filter slot system, the LEE100 Filter Holder from LEE Filters can be quickly configured to hold up to one, two, or three separately available 100mm-wide, 2mm-thick filters along with a separately available polarizer filter.

Constructed for durability while remaining lightweight, use of the LEE100 Filter Holder is easily accomplished by first screwing a separately available LEE Filters adapter ring for a 100mm system filter holder onto a lens with corresponding front filter threads. After being fitted onto an adapter ring, the filter holder's pull-and-release locking knob helps to provide a reliable, yet adjustable connection that allows the holder to be rotated 360°, allowing the use of graduated neutral density and other filters that are enhanced by varied positioning. Featuring three user-selectable positions, the locking knob can be set to allow the filter holder to be rotated or removed from an adapter ring. By progressively turning the locking knob, the filter holder can be locked onto an adapter ring while it is rotated, or it can be locked onto an adapter ring with no rotation.

Three pairs of snap-on LEE Filters Filter Guide Blocks are included. When installed, a guide block pair creates one, two, or three slots for 100mm-wide, 2mm-thick filters and accommodates a separately available LEE Filters LEE100 Polarizer Filter. This filter can be snapped directly onto a LEE100 Filter Holder's guide blocks without occupying any of their filter slots. Alternatively, a separately available LEE Filters 105mm Polarizer Ring allows a separately available LEE Filters 105mm Landscape Circular Polarizer Filter to be adapted to the LEE100 Filter Holder without occupying any of its guide blocks' filter slots.
