Heliopan, our highest-quality filter, has now entered the Variable ND market with this excellent offering. It can vary from 1 to 6.6 stops of ND filter by simply rotating the outer ring.
It’s perfect for times when you aren’t sure how bright the light may be, and provides an alternative to carrying a set of several ND filters. It’s great for snow, white beaches, waterfalls—any time you may want a longer exposure.
