Using the rotating 67mm Vario Neutral Density Filter from Heliopan, can reduce the exposure on your film or digital camera anywhere from 1.0 to 6.6 f/stops. When shooting with high ISOs, this filter can allow you to shoot under bright lighting conditions such as at the beach. This is also an ideal filter for creating long exposure special effects such as capturing the "blur" of running water. It also permits you to control your depth of field by helping isolate your subject from its background by using a wider aperture. A convenient index scale on the filter ring makes exposures repeatable and exact. Neutral density filters appear gray and have no effect on color.
The filter is thin enough (8.7 mm) to use with wide-angle lenses without vignetting (the darkening of the corners of the image). It has been tested on a Canon 16-35 "L" lens without vignetting down to f/16. Another advantage of this filter is that it saves you the expense of having to purchase individual neutral density filters. This, too, is a time saver since you won't have to search through your bag to find the filter you want. Just rotate the Vario Neutral Density until you achieve the degree of ND you desire.
The filter is made with world-renowned Schott glass that is supported by a rugged black brass filter ring that is less prone to jamming than traditional aluminum filter rings.
Heliopan has been a leader in the filter industry since 1949. They are known for their high-quality and production standards. Their slim mounts facilitate using them with wider angle lenses. Heliopan offers most of their filters with either their standard hard coating or with their industry leading SH-PMC 16 layer multi-coating that transmits over 99.5% of the light striking it on to the image plane for the lowest flare and greatest color saturation.

Comments about Heliopan 67mm Vario Neutral Density Filter:
I use it in a Sony E mount 18-200 mm lens with the Sony Nex Fs100. It works great but between the 18mm and 35 mm of the zoom the filter has a noticeable darker gradation at the diagonal borders of the image. So don´t expect to use wide angles. I´ve read this is a common problem of variable nd, I just expect that being 3 times more expensive than other variable nd filters this Heliopan would not have this problem, but it does, so I wonder if It should have buy one variable nd from a cheaper brand.
