The Landscape Kit is an excellent starting point for landscape photography, with a filter holder and one filter.The Landscape Kit contains both the LEE100 Holder and a 100 x 150mm Medium Graduated Neutral Density 0.6 Filter which is a useful first filter for landscape photography. This helps you balance the exposure between the bright sky and the darker land. The LEE100 Filter Holder features a modular, snap-on filter slot system that can hold up to three separate 100mm-wide, 2mm-thick filters and a polarizer filter. Its lightweight yet durable construction allows for easy use by attaching a LEE Filters adapter ring onto a lens with corresponding front filter threads. The filter holder's pull-and-release locking knob can rotate 360° and has three user-selectable positions, providing a secure and adjustable connection for various filter positioning. It can also be locked onto an adapter ring while being rotated or locked onto an adapter ring without rotation, depending on the preference of the user. The Kit includes three pairs of snap-on Filter Guide Blocks. These blocks create one, two, or three slots for 100mm-wide, 2mm-thick filters and can be used with the separately available LEE Filters LEE100 Polarizer Filter without occupying any of the filter slots. Alternatively, the LEE Filters 105mm Polarizer Ring and 105mm Landscape Circular Polarizer Filter can be adapted to the LEE100 Filter Holder without taking up any of its guide blocks' filter slots. Pouches are also included for storage and transport of the LEE100 Landscape Kit's components.
