Heliopan 77mm Variable Gray ND Filter
Key Features
  • 0.3-1.8 Variable Neutral Density Filter
  • Increase Exposure by 1 to 6 Stops
  • Brass Ring Construction
  • High Quality Schott Glass
The Heliopan 77mm Variable Gray ND Filter is a solid variable neutral density filter providing a reduction of about 1 to 6 stops. The 0.3 to 1.8 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. The degree of density is easily controlled by rotating the front filter ring, allowing you to previsualize the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image.

question

Hello, will this ND filter setup work with a Leica R lens? if so, which ones? I have a 50mm f2 Summicron, & a 24mm Elmarit f2.8. I need an ND filter that will work with both of these. Thanks very much!Julian Wayser
Asked by: Anonymous
There are many versions of the Leica 50mm f/2 Summicron-R lens. Early versions (1964-1976 black; 1964-1966 chrome) were a Series VI + 14160 (Series VI - E44 filter adapter) and later II models (1976-2009 black) are Internal thread for screw-in type filters E 55 size with a Built-in, telescopic hood. The 24mm f/2.8 Elmarit-R was a Series 8 and our records show some may have been an E60. 72mm to Series 7 Filter Adapter B&H # LEARS77282mm to Series 8 Filter Adapter B&H # LEARS88255mm NDs http://bhpho.to/1m7oEIA

question

Mine has developed a haze between the two filters. Is there a way to take it apart and clean it?
Asked by: Anonymous
I have exactly the same issue, haze inside the filter. I live in Thailand and after contacting Heliopan there seems to be no support whatsoever outside USA. It's a hugely expensive filter that basically for me is unusable. I asked for instructions to open it but they gave me none. Many ppl have the same issue with this vnd but there is no solution anywhere if you live outside US. I saved a long time to get this and am hugely disappointed.
