82mm ND Filter From Heliopan
October 18, 2011
HP Marketing (Pine Brook, NJ, www.hpmarketingcorp.com) is now offering an 82mm version of the Heliopan Vario ND filter. The new filter is adjustable from 1 to 6.6 stops of ND (0.3 to 2.0 density); it is neutral in color and mounted in a black anodized brass ring that is numerically calibrated with an index for added convenience. To save time in set-up and use, the filter’s adjustable range is hard stopped at each end. The new filter accommodates a wide variety of lenses, including lenses as wide as 16mm, all without the color shifts, vignetting or artifacts that are common in other variable ND filters.
