The Hitech Lucroit 165mm Filter Holder with Adapter for Nikon 14-24mm Lens and Grad ND 0.6 Hard Edge Filter Kit contains the essential components for using filters with your Nikon 14-24mm f/2.8G wide angle lens.
The 165mm Lucroit Filter Holder is able to hold 2 separate 165mm filters at a time as well as rotate a full 360°, permitting the use of graduated neutral density filters and other filters that are enhanced by varying positioning. Included with the filter holder is the adapter ring specifically designed for the Nikon 14-24mm lens which features no filter threads.
Also included with the kit is a 6.5 x 8" / 165 x 200mm hard-edged graduated 0.6 neutral density filter. This filter helps to darken skies and other bright areas of the image by placing a 2-stop density at the edge of the filter and tapering it towards the center of the filter plane. It is constructed from specially dyed CR-39 resin.
