Polar Pro 67mm (6-9 Stop) Variable Neutral Density Filter Peter McKinnon Edition

A must have product for amateur film makers who does a lot of run and gun. Highly recommend for individuals who has a lot of money to spend for a vario ND filter.

Nothing at all to dislike about this ND filter, yea I know its a bit pricey but its definitely worth it.

This is one of the rare moments where I have absolutely nothing bad to say about a product. It is perfect.

Love the filters! I have the 2-5 stop as well. No vignetting.

Worked great! No color cast and easy to take on and off.

As advertised very good quality

the item inside was not variable ND so i returned it with a refund. disappointing

I purchased the 82mm 2-5 stop version of this filter.Great IQ, hard stops, and accessories.But if you want to screw another filter or lens hood onto this filter, can't do it.No female threads.This little detail isn't mentioned ANYWHERE in reviews or marketing, so beware.If this isn't as important to you as it is to me, then DEFINITELY buy this filter!You will NOT be disappointed!UPDATE 5/14/19 - PolarPro's response to my female thread complaint explained they designed the filter to be very thin so as to not create vignetting in focal lengths as wide as 16mm.I'd still like to see a non low-profile, stackable version of this filter.
