PolarPro Helix Peter McKinnon Edition 4-Slot Filter Case

To use the PolarPro Helix Variable Neutral Density Filter (6 to 9 Stops) on the Nikkor Z 70-200mm f2.8 you will need to purchase this PolarPro Helix 77mm adapter ring separately. https://www.bhphotovideo.com/c/product/1767533-REG The Nikon NIKKOR Z 400mm f/4.5 VR S Lens has a 95mm filter thread and unfortunately the Helix adapter ring does not go to that size. Maximum they have is 82mm.

According to the manufacturer, the PolarPro Helix Variable ND Mist Filter (2 to 5-Stop) provides 1/8 diffusion. The same goes for the PolarPro Helix Variable ND Mist Filter (6 to 9-Stop), B&H # POPM69MIST.

PolarPro Helix Variable Neutral Density Filter (2 to 5 Stops) is not a 82 mm filter. The Helix Variable Neutral Density Filter from PolarPro is designed for the Helix magnetic filter system and provides an exposure reduction of 2 to 5 stops. Variable ND filters are not designed to be used with the lens hood attached and the front element has a different size than the filter thread.
