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.

Helping to balance exposure when working in high-contrast situations, the 100 x 150mm Hard Graduated Neutral Density 0.6 Filter from LEE Filters is specifically designed to selectively control brightness in difficult lighting. The filter's design places the 0.6, 2-stop density at the top of the filter and then transitions to clear by the center of the filter for a gradual, natural appearance. The hard-edge transition between the density and clear areas is well-suited for photographing scenes with an even, distinct horizon line, as well as when working with long or telephoto lenses. This filter is constructed from optical resin that is both durable and helps to maintain high clarity, and is compatible with the LEE 100mm filter holder.

The LEE Filters 100 x 100mm Big Stopper 3.0 Neutral Density 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.

The LEE Filters 100 x 100mm Little Stopper 1.8 Neutral Density Filter is a solid neutral density filter providing a 6-stop reduction in exposure. This 1.8 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.
