The SW150 Mark II Holder fits to the lens via a lens Adaptor that needs to be purchased separately from the filter holder. Each Adaptor consists of a front ring, a compression ring and a locking ring that have been specifically designed for each particular lens. When fitted, they form a collar that remains on the lens at all times. Lee Filters' are working on Adaptors for additional ultra-wide-angle lenses so check back if your lens isn't yet listed. The Adaptor consists of a front ring, a compressor ring and a locking ring specifically designed for the Nikon AF-S Nikkor 14-24mm f/2.8G ED lens.
