Designed specifically for the Nikon 14-24mm f/2.8G ED, the Master Series 150mm Filter Holder from Benro uses a compression ring that fits tightly around your lens for quick mounting and unmounting. It holds up to three 150mm filters simultaneously, including a circular polarizer, and supports models as thick as 2mm. The product is made of precision-machined aluminum for increased durability. Included in the package is a 95mm mounting ring and a 95-77mm step-down ring, which allow you to use the holder with other lenses that have either of those front filter threads.
