This 2-stop, Bay 3 Heliopan 2-Stop ND Filter Bay 3is 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.

Q: 1. Can this filter be safely used as a solar filter to film the upcoming solar eclipse?

Q: 2. 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: 3. What's the actual filter weight (not package shipping weight) in grams. Looking for options for drone lens...?

A: Sorry, we do not have the actual weight on record and we cannot weigh it. I would subtract a few ounces to get at the weight you need to know.

Q: 4. I've got a few questions about this heliopan ND filter i was hoping i can get help on.1. Is this a multi-coated filter?2. Will it vignette with wide angle lenses (i.e. 16-35mm Canon f4L lens)?3. does it have front filter threads?

A: Not sure on the multi coating, but I believe they are at least single coated. This filter is relatively thin, so vignetting should not be a problem on that lens. Yes, they have front filter threads. With that said, I would recommend checking out the Firecrest ND filters. They are very thin, have front threads and they have great multi coating.

Q: 5. 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.
