Haida Magnetic Variable ND NanoPro Interchangeable Filter 77mm

The 77mm NanoPro Magnetic Interchangeable Variable ND 2-Filter Kit from Haida combines a pair of variable neutral density filters with a magnetic filter ring for a fast density adjustment range from 2 f/stops to 9 f/stops. The aircraft-grade aluminum ring screws onto the 77mm front filter thread of a lens, allowing either the 2-5 f/stop filter or the 6-9 f/stop filter to be attached or exchanged in just seconds. The filter ring features front filter threads, allowing it to stay on the lens and have a lens cap attached when not in use.
