This 6-stop, 67mm NanoPro Magnetic ND Filter with Adapter Ring from Haida provides a 6-stop reduction the amount of light passing through your lens. Increasing neutral density offers control in available shutter speeds or aperture settings for both still and video applications. Using a longer shutter speed makes it possible to increase motion blur to create special effects or convey a sense of movement. Increased density also makes it possible to shoot using wider lens apertures, helping to isolate a subject from the background by creating shallow depth of field without overexposing your image.
This magnetic filter attaches to an included adapter ring that screws onto the front filter ring of your lens, and can easily be swapped out.The adapter ring has both front and rear threads and accepts a standard threaded lens cap as well as a Haida magnetic lens caps, allowing you to leave the ring on your lens. The ND1.8 filter features glass optics with a top coating that protects against water, oil, dust, fingerprints, and scratches.
