Heliopan ships Vario ND variable filters in sizes from 55 to 82mm
Heliopan has started shipping variants of its Vario ND variable neutral density filters in sizes from 55 to 82mm, according to its US distributor, HP Marketing. The filters provide 1–6.6EV filtration and include numerical markings to allow you to precisely dial-in the desired density. The filters feature brass construction and are shallow enough to be used with lenses as wide as 16mm equivalent.
NEW HELIOPAN VARIO ND FILTERS NOW AVAILABLE IN SIZES UP TO 82MM
August 11, 2011: Heliopan has just begun shipments of their new Vario ND filter in 82mm size. Like the 52 to 77mm sizes it is adjustable from 1 to 6.6 stops of ND (0.3 to 2.0 density) by simply rotating the calibrated rim of the filter. The Heliopan Vario ND filter is totally neutral in color, it is mounted in a black anodized brass ring that is numerically calibrated for ease in repeating a desired density. The cali- bration scale has an index for added convenience and the adjustable range is hard stopped at each end to save time in set-up and use. The Heliopan Variable ND filter is very thin (8.7mm from the front edge to the front of the lens) to allow it to work on lenses as wide as 16mm without color shifts, vignetting or artifacts common in other variable ND filters.
The new Vario ND filter is now available in screw-in sizes from 52 to 82mm. The new Heliopan Vario ND filters are available from camera stores in the USA.
