This 3-stop, 67mm Heliopan 67mm ND Filter - 3 Stopprovides a 3-stop exposure reduction. Its 0.9 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image. By slowing your exposure time, you can create motion blur for special effects or to convey a sense of movement. Opening your iris allows you to create shallow depth of field, which can help isolate your subject. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

To prevent internal ghosting and reflections, each glass surface includes four layers of anti-reflection coating. Together, these eight coatings offer greater protection to the filter substrate and help it to stay clean for longer than with uncoated filters.

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

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. Will this filter also cut out IR?

Q: 6. 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.)
