The Lee Foundation Kit is the basic element of the Lee filter holder System. This kit contains all the necessary components (including a small screwdriver) to construct a versatile holder which will take up to four filters. When assembled, the holder in it's standard form accepts three filters - 100mm (4") wide x 2mm thick and one additional 100 x 100mm (4x4") gelatin filter. It also holds 4x6" (100 x 150mm, 2mm thick) filters.
Lee makes a variety of standard and wide angle adapter rings in screw-in and bayonet sizes as well as accessory compendium shades. When mounted, this holder will rotate on the adapter ring for positioning a polarizer or a graduated filter. Optional "side-guides" and guide mounting screws in shorter/longer lengths are available for use with 1mm and 4mm thick filters.
Note! To use this holder, an optional adapter ring must be purchased
