The Heliopan 77mm Polarizer Filterhelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

The front and rear surfaces of the filter both feature a single anti-reflection coating. Each coating helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, they offer protection to the filter substrate while helping to keep the glass clean for longer than uncoated glass.

This Heliopan filter is constructed from Schott glass for increased optical clarity and color fidelity. It features a brass filter ring for durability as well as jamming prevention.

Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° from the sun.

Single coatings on both the front and rear offer protection to the glass and help to improve light transmission and image quality.

Constructed from Schott glass for optical clarity.

Brass filter ring helps to prevent jamming and provides additional strength.

Dual threading with 77mm front filter threads permits combining with other filters.

Q: 1. Does this filter have hard stops? Will it be OK for video use?

A: This filter does not have hard stops but turns smoothly. I have not tried it for video but believe it would apply appropriately.

Q: 2. Would this Heliopan Variable ND filter fit a sony lens?

A: Whether this filter would fit depends on which Sony lens you own.

Q: 3. will this fit a 35mm nikon 1.8 dx lens?

A: The Nikon AF-S DX NIKKOR 35mm f/1.8G Lens has a 52mm filter thread, so will be compatible with the Heliopan 52mm Circular Polarizer.

Q: 4. Mine has developed a haze between the two filters. Is there a way to take it apart and clean it?

A: 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.

Q: 5. Can this filter be safely used as a solar filter to film the upcoming solar eclipse?

A: What if one uses live view?

Q: 6. does this affect colors in any way? does it desaturate colors as those cheaper ND filters?

A: No, this filter does not affect coloration of the image.

Q: 7. What's the diameter of the lens cap to buy for the Heliopan 46mm variable ND filter? Trying not to remove the filter each time the camera is kept in the bag, thus a lens cap would be useful.

A: The filter can only be used with a push on lens cap. There are none that are specific for that filter. This one is very close but can at times slip off.

Q: 8. What if live view is used?

A: To my original answer, I should add that on a Leica M, the EXIF data will probably show a different aperture to the one on the lens.The Ms have no electrical connection between camera body and lens, so the camera infers aperture for EXIF by comparing light intensity metered at the shutter compared to the ambient light on the body. (That's what the small light meter hole on the front top of the body is for.)

Q: 9. 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

A: 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

Q: 10. Will this filter also cut out IR?

A: This filter does not offer IR cut capability.
