This 2-stop, Bay 2 Heliopan 2-Stop ND Filter Bay 2is a solid ND filter. This 0.6 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.

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.

A: Yes, the 60mm Heliopan variable ND filter attaches directly to the Leica 50mm Noctilux f/0.95. It is a great quality filter and easy to use. It is good not to need a step up ring and you can extend the built in Noctilux lens hood over the filter. However, same as BW filter, you can't use the Leica noctilux lens cap directly on it.

Q: 6. 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.
