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.

This 100 x 100mm LEE Filters Big Stopper ND Filter is a solid neutral density filter providing a 10-stop reduction in exposure. This 3.0 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

This filter is constructed from a high quality optical glass for high definition and clarity. It is compatible with the 100mm Filter System, which is designed for use with most lenses and camera types. This filter measures 3.9 x 3.9" / 100 x 100mm.

This 77mm Adapter Ring from LEE Filters is designed to enable the use of a LEE Filters 100mm System filter holder on a wide-angle lens while helping to prevent vignetting. It is compatible with lenses that feature 77mm front filter threads and features an aluminum-alloy construction for durability while remaining lightweight.

Keep your optical surfaces clean with the Sensei OC-CK Optics Care and Cleaning Kit. This kit contains a pack of lens tissues, a lens cleaning pen, bulb air blower, paint brush, lipstick brush, lens cleaning fluid, microfiber cleaning cloth, and see-through mesh travel case to put everything in. This kit can be used to clean a variety of different optics and glass. You can use the air bulb blower and any of the three supplied brushes to initially remove dust from the surface. Sensei recommends applying a small amount of the alcohol- and ammonia-free cleaning fluid directly to the lens tissue. Then, gently rub in small circular motions to remove stubborn smudges or fingerprints from the glass. For those more stubborn blemishes or smudges, the lens pen is very effective.
