The holder is the foundation of the LEE 100mm System and comes assembled with two filter slots. It fits to the lens via adaptor rings which enable the holder to be used across a wide range of lenses.
The holder is designed to be compatible with the standard LEE 100mm filters, including ND Grads, Stoppers and Polarizers. These can be combined for almost limitless creative options and precise exposure control.
Simply slide filters into the holder and position precisely where you need them. Crucially the holder can also be rotated to any angle, enabling the light to be controlled no matter where it's falling in the frame.
A range of accessories are also available to add extra filter slots and further increase the options.
