This 4 to 9-stop, 67mm Haida NanoPro NDFilter 67mm 4-9 Stop Variableprovides an exposure reduction of 4 to 9 stops. The 1.2 to 2.7 optical 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, helping you to predetermine the additional exposure length required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is also visually demarcated with dots that represent different density values and includes a rotation lever to further enable fast, as well as precise positioning of the front ring.

This filter is constructed from optical glass for clarity and color fidelity. To prevent internal ghosting and reflections, each glass surface includes 10 layers of anti-reflection coatings, which also offer greater protection to the filter substrate and help keep it clean for a longer period of time. The Nano coating associated with the Haida 67mm NanoPro Variable Neutral Density Filter provides an additional layer that results in an improved beading effect when the surface comes in contact with water or oil, allowing for more efficient cleaning.

Related Questions and Answers

Q: 1. Will the Haida magnetic vnd filters vignette on a 15mm lens? I have the Laowa 15mm f/4 macro.

A: The Haida 77mm NanoPro Magnetic Interchangeable Variable ND 2-Filter Kit could possibly cause slight vignetting using the 15mm lens.

Q: 2. does the canon lens cap the comes with a 77mm fit on this filter? the older Hoya I have I can not fit my canon lens cap on

A: No, like most variable ND filters, the lens cap that came with the lens will not fit on to the Hoya 77mm Variable Density II Filter.

Q: 3. What size Push-On lens cap do I need for this filter? The frame of the filter seems to be larger than 82mm

A: If you are planning on keeping the step ring on while you shooting yes you will have to buy an 82mm cap

Q: 4. is the level detachable? If so, can I still use the lens hood on my rf 24-105mm without the level?

A: The lever is detachable but the filter ring is too large to be used inside the Canon hood. A screw on hood could be used instead such as this: https://bhpho.to/35j7SrF

Q: 5. I've read and heard online that this filter effectively cuts some measure of IR. How true is this?

A: Syrp does not list any specifications on IR transmittance. Without a listed specification, this is subject to product variance. It is impossible to guarantee a specific IR attenuation.

Q: 6. How thick are these filters?

A: The Haida NanoPro Magnetic ND3.0 Filter (95mm, 10-Stop) is 3.1mm thick.

Q: 7. Will the filter fit into the leather pouch with the 7282 step up ring attached to it? It is hard to tell from the photos.

A: Yes the filter fits in the leather pouch with the 7282 step up ring attached or detached to it. I think you can even fit both step up rings into the leather pouch along with the filter. You could use a small microfiber cloth to separate them from the filter.

Q: 8. Does it have a hard stop at each side of the scale, so it won't rotate too much?

A: The Haida NanoPro Variable Neutral Density 1.2 to 2.7 Filter (77mm, 4 to 9-Stop) does not have a hard stop, but it's design allows for smooth transition between stops and stays in place.

Q: 9. Will the Haida magnetic filter (77mm) stick to a different brand 77mm magnetic ring?

A: Technically it should fit other brand rings. Note, it has not been tested with any ring but the one it is made for.

Q: 10. I see the filter does not protrude from the sides like most NDs. Can you use the original lens hood with this filter?

A: Most likely, yes, but it depends on the lens and the hood.
