This 4 to 9-stop, 52mm Haida NanoPro Variable ND Filter provides 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 52mm 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. Does this filter work with any other metal UV filter placed on the lens?

A: Unfortunately, the Haida NanoPro Magnetic Clear Night Filter (82mm) does not work with any other metal UV filter placed on the lens. It requires the Haida 82mm Magnetic Adapter Ring screwed onto the lens or the front of your UV filter if it has 82mm diameter filter threads and then you can use the Haida NanoPro Magnetic Clear Night Filter (82mm) over the adapter ring. https://bhpho.to/3xTA7FZ

Q: 2. So if I buy this set, would I be able to use it with my lenses 57mm all the way to 82mm in my R5 ?

A: Yes you could stack these and place an 82mm filter on a 37mm lens. You can also use them one at a time for a smaller change for example to use 62mm filter on a 58mm lens.

Q: 3. Does this cause vignetting when used on the Sony 16-35mm G PZ lens?

A: The H&Y Filters RevoRing 52-72mm Variable Adapter for 77mm Filters should not cause any vignetting when used with the Sony 16-35mm lens.

Q: 4. Will these work with a filter holder like a Nisi V6 or V7? That is, can I use the 82mm adapter to put the Nisi holder on a range of lenses?

A: The H&Y Filters RevoRing Variable Adapter Bundle (3 Adapters) are compatible with screw-in filters only.

Q: 5. 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: 6. Is this filter multi-coated?

A: Yes, the Haida 58mm NanoPro Magnetic Interchangeable Variable ND 2-Filter Kit would be multi-coated.

Q: 7. Can this be used with K&F magnetic rings?

A: The Haida NanoPro Magnetic Clear Night Filter can't be used with K&F magnetic rings.

Q: 8. I'm using a B&W 77mm KSM HTC polarizer. Will this filter thread on to my polarizer?

A: Your B+W High-Transmission Circular Polarizer would have a front thread to accept another filter like the K&F Concept ND8-ND2000 Nano-X Variable ND Filter with Multi-Resistant Coating (77mm).

Q: 9. I'm unclear. I have lenses 52-72mm. I assume I would need a RevoRing 52-72mm Variable Adapter...plus what exactly? Their kickstarter page is even more confusing.

A: This adapter fits on lenses with a 52-72mm filter thread in order to allow the use of 77mm filters on it.

Q: 10. I have 67mm polarized filter that i want to use on lenses that are smaller then 67mm(48-67) ..... which rovering to choose ? the 67mm or the 77mm ?

A: This H&Y RevoRing for 77mm filters will not work on your 67mm CPL filter. You should instead consider the H&Y RevoRing for 67mm filters, because that will work with your 67mm filter.
